Important Safety Instructions  
WARNING: High Energy and High Voltage  
Exercise caution when using and calibrating a power supply.  
High energy levels can be stored at the output voltage terminals  
on a power supply in normal operation. In addition, potentially  
lethal voltages exist in the power circuit and on the output and  
sense connectors of a power supply with a rated output greater  
than 40 V. Filter capacitors store potentially dangerous energy  
for some time after power is removed.  
CAUTION  
Operate the power supply in an environment free of flammable  
gases or fumes. To ensure that the power supply’s safety  
features are not compromised, use the power supply as specified  
in this manual and do not substitute parts or make any  
unauthorized modifications. Contact the service technician for  
service and repair help. Repairs must be made by experienced  
service technicians only.

Installation and Configuration  
Changing Internal Jumpers  
Some of the settings on the Ethernet/RS-232 Interface card are user  
selectable by way of jumpers on the printed circuit board. The procedure  
for changing the jumpers varies depending on if you have a 1.2kW XFR,  
or a 2.8kW XFR.  
CAUTION  
If you remove the unit's cover, use proper static control  
techniques to avoid damage to static-sensitive components on  
the printed circuit board.  
Procedure for 1.2kW XFR  
Ensure that the input power connection has been disconnected and the  
unit is powered off before you attempt to remove the top cover. Remove  
all the screws holding down the top cover and then remove the cover. The  
printed circuit board that you need access to is upside down (component  
side down), so you must remove all the screws that are holding it in place.  
Refer to Figure 2-4 to see which screws should not be removed.  
During service, do not  
remove these screws

Changing Internal Jumpers  
Once that is complete, turn the board over and, if necessary, remove the  
short ribbon cable connected to J64 on the interface card to get access to  
the under side of the PCB. You can now scan the board and refer to Figure  
2-3 to locate the various components and jumpers on the PCB. Once you  
have made the necessary changes, reconnect the ribbon cable, screw the  
PCB back in place, and screw the top cover on.  
Procedure for 2.8kW XFR  
Ensure that the input power connection has been disconnected and  
the unit is powered off before you attempt to remove the top cover.  
Remove all the screws holding down the top cover and then remove  
the cover. The printed circuit board that you need access to is right  
side up (component side up), so refer to Figure 2-3 to locate the  
various components and jumpers on the PCB. Once you have  
located the jumpers and made the necessary changes, return the top  
cover to its proper position, and screw it back in place.

Installation and Configuration  
Configuring for Ethernet or RS-232  
This interface card can be configured for Ethernet communication, or for  
RS-232 communication, but not both simultaneously. From the factory,  
the instrument will be configured for Ethernet communication. Therefore  
you should only need to follow these instructions if you are switching  
over to RS-232, or back to Ethernet. To switch between the two  
configurations, you must change internal jumpers on the interface card.  
See “Changing Internal Jumpers” on page 2–8. Also refer to Table 2-2  
and Figure 2-3 on page 2–6 to locate the corresponding jumpers.

When you have finished changing the jumper positions, ensure that the  
baud rate, flow control, and power-on state are configured properly for  
your new setup. These settings are also changed by adding or removing  
jumpers, so it is best to perform this adjustment, if necessary, while the  
interface card is accessible. Refer to “Baud Rate Selection” on page 2–18,  
“Flow Control Selection” on page 2–19 and “Remote/Local Mode  
Startup” on page 2–20 for more detailed information on how to  
reconfigure these settings.  
Note: If you are switching the interface card back to Ethernet it is  
recommended to set the baud rate to 9600, turn flow control off, and  
have the unit power-on in remote mode (these are the default settings).

Ethernet Communications  
Ethernet Communications  
Ethernet Connection  
There are two options for controlling your XFR power supply via  
Ethernet - "Connecting to a Network" or "Connecting Directly to your  
Computer." The first option is to connect the power supply to a network,  
and control the unit from your computer which is also connected to the  
network. The second option is to connect the XFR directly to your  
computer's network interface card (NIC). This bypasses the need for an  
existing network.  
Connecting to a Network  
All that is required to connect your XFR to a network is a straight through  
CAT 5 network cable and an available network port.  
Connecting Directly to your Computer  
To connect your XFR directly to your computer you will need a cross-  
over CAT 5 network cable. You will also need to check your network  
settings on your computer to ensure that you are using a static IP address.  
Check with your IT department for assistance.  
TM-XR9B-01XN  
2–13  
 
Installation and Configuration  
Locating the Power Supply on Your Network  
1. Record the MAC address for your power supply. This will be visible  
at the back of the XFR, on the interface card subplate. For example,  
MAC Address  
00429D 22EF45  
MAC Address:  
______________________________  
2. Insert the Xantrex XFR Ethernet Software Utilities CD into your CD  
drive.  
3. If the CD does not start automatically, double-click the My Computer  
icon, double-click the CD icon and then double-click  
autorun_main.htm.  
4. When the menu appears, click Xantrex Device Discovery to install  
and run the application. This application will find and list all XFR’s  
with an Ethernet/RS-232 Interface card on your network.  
5. You can now scan the list and locate your new XFR by its MAC  
address.  
6. If your network uses a DHCP server and DHCP was enabled on the  
XFR, your new instrument will already have an IP address. If not, you  
will have to configure an IP address manually. Refer to steps 2 and 3  
in “Configuring Ethernet Bridge” on page 2–15 for more information.  
7. Write down the IP address so that you can access the instrument via  
its web server, and for when you start communicating with the power  
supply.

TM-XR9B-01XN  
 
Ethernet Communications  
Configuring Ethernet Bridge  
The Ethernet/RS-232 Interface card has an Ethernet Bridge that converts  
the ethernet packets to serial data signals for processing by the embedded  
microcontroller. The Ethernet Bridge must be properly configured for  
serial communications with the microcontroller. For example, settings on  
the Bridge, such as Baud Rate and Flow Control, must match the jumper  
settings on the interface board.  
There are two ways to gain access to the configuration menu for the  
Ethernet Bridge. One is to run the Setup program that is available on the  
Software CD. This program will find your instrument and allow you to  
configure it by clicking on the instrument’s IP address. You will then need  
to enter the correct username and password to be able to configure the  
device.  
Default Username: root  
Default Password: dbps  
The other method is to open up a web browser like Internet Explorer, and  
type in the IP address for the instrument. Again, you will be asked for the  
username and password. Once you have accessed the configuration page,  
follow these steps for proper setup.  
1. Click Configuration > Serial Port, and ensure that the following  
settings have been selected:  
Baud Rate:  
Data Bits:  
Parity:  
Stop Bits:  
Flow Control:  
9600  
8
None

None  
Click Apply once you have finished adjusting the above settings.  
2. Now click Configuration > Network. If your network uses a DHCP  
server (ask your IT department) you should select Obtain IP address  
automatically using DHCP and then click Apply. If your network  
doesn’t use a DHCP server, select Use the following IP address: and  
enter an appropriate IP address, Subnet Mask and Default Gateway. .  
3. Ask for assistance from your IT department to obtain an appropriate  
IP address, Subnet Mask, Default Gateway, Name Server, and  
Domain. Once you have made the appropriate changes, click Apply. If  
this changed the setting, the device will reboot, so you will have to  
renew your connection to its configuration webpage for any further  
configuration changes.

Installing and Using RealPort®  
Background  
RealPort® software allows you to keep using your existing applications  
that rely on COM ports and RS-232 links for communication purposes,  
instead of having to develop TCP/IP based network applications. Installed  
on a network-enabled PC, RealPort® creates a virtual COM port. As  
such, your application still thinks it is working with a real serial port, such  
as COM1. When the application sends data to this serial port, RealPort®  
ships the data across the network to the Ethernet Bridge in your power  
supply. By doing this, the network is transparent to your existing  
application.  
Installation  
RealPort® can be installed on any PC running Windows NT 4.0,  
Windows 2000, or Windows XP.  
1. Insert the Xantrex XFR Ethernet Software Utilities CD into your CD  
drive  
2. If the CD does not start automatically, double-click the My Computer  
icon, double-click the CD icon and then double-click  
autorun_main.htm.  
3. When the menu appears, click Digi RealPort®.  
4. Follow the on-screen instructions for proper installation.  
Note: RealPort® drivers for UNIX systems are available. Contact your  
Xantrex representative to obtain these drivers if necessary.  
Using RealPort®  
Once you have installed the RealPort® driver for your power supply,  
using it is as simple as running your existing application (such as  
HyperTerminal, or a custom RS-232 application) and setting the COM  
port to be the one created by the RealPort® driver for your instrument.

With the PON REM jumper open, the power supply will start up in  
remote mode. The green REM LED on the front panel will be lit,  
signaling that the power supply is under the control of the digital interface  
card. The output of the power supply is active on startup. To promote load  
safety, power ON defaults are zero for the output voltage and current  
limit, and 110% of maximum output voltage for the OVP trip point. See  
Table 2-10. Refer to “Operation” for more information about the interface  
commands listed in the table.  
If the PON REM jumper is closed, the power supply will power up in  
local mode. Power supply control is at the front panel. During an  
operating session, you can toggle between local mode and remote mode  
by using the front panel LOCAL button or sending commands as  
described in Table 2-10.  
Note: The default setting for this jumper is open. If you require it to be closed  
(PON in local mode) you can obtain a spare jumper by removing the one that  
connects pins 11 and 12 on J2 as these pins are unused.

Remote Mode Operation  
While in remote mode, use the interface commands to control the output  
of the power supply from a computer. See “Operation” for a complete list  
of device-dependent commands available with this interface.  
From remote mode, change to local mode operation by pressing the front  
panel LOCAL button or by sending either the GTL command or the  
REN OFF command. You can disable the LOCAL button by using the  
LLO command. For an example of how to use Local Lockout, see “Local  
Lockout (LLO) Command” on page 2–23.  
To return to remote mode, ensure that the REN command is set to ON and  
then send any valid device-dependent command. Since the remote mode  
output settings may be different from the local mode settings, the output is  
programmed to protect the load by turning off when you toggle from local  
to remote mode during a session. Check your remote settings and then  
send OUT ON to restore the output.

Installation and Configuration  
Local Mode Operation  
In local mode operation, you set the voltage and current output levels and  
the OVP trip level with controls located on the front panel. Refer to the  
operating manual for a description of the functions available at the front  
panel.  
While in local mode operation, you can change power supply control to  
remote mode by ensuring that REN is ON, then sending any software  
command and OUT ON to restore the output. Return to local mode by  
pressing the front panel LOCAL button, unless Local Lockout is in effect.  
If LLO is in effect, use the GTL command to send the power supply into  
local mode, or use the REN OFF command to turn off LLO and return the  
power supply to local mode.  
Example:  
Press the LOCAL button  
Id?  
Set unit to local mode  
Put the unit into remote mode  
(Use any command to do this.)  
Press the LOCAL button  
Return to local mode.  
Remote Enable (REN) Command  
You can use the Remote Enable command to toggle between local mode  
and remote mode. The default setting at startup is REN ON. With the  
remote enable command set at REN ON, you can return the power supply  
to remote mode whenever you send any command from the computer.  
Any time that you change from local to remote mode during a session, the  
output is programmed to turn off, since the remote mode settings may be  
different from the local mode settings. Send the OUT ON command to  
restore the output.  
You can turn off Remote Enable and move power supply control to the  
front panel by sending the REN OFF command. If the Local Lockout  
condition is in effect, sending the REN OFF command will turn off the  
LLO condition before sending the unit into local mode.  
To check whether the power supply is remote enabled, use the REN?  
query command.  
Example:  
REN ON  
Enable the power supply to be sent into  
remote mode  
VSET 10;ISET 2  
Put the unit into remote operation mode  
(Use any command to do this.)

Power Supply Settings  
Local Lockout (LLO) Command  
Use the Local Lockout command to disable the LOCAL button on the  
power supply front panel. With LLO in effect, you cannot return to local  
control by pressing the front panel LOCAL switch. You can still return to  
local mode by sending the Go to Local (GTL) command. However, to turn  
off LLO and return the power supply to local mode, send the REN OFF  
command. Only the REN OFF command will remove the LLO condition.  
Example:  
LLO  
GTL  
Set Local Lockout  
Return the power supply to local mode.  
Local Lockout is still in effect  
REN OFF  
Turn off Local Lockout and return the  
power supply to local mode  
Power Supply Settings  
For serial communication, the computer and the Ethernet/RS-232  
Interface must share the same communication settings. Make sure that the

Installation and Configuration  
Additional User Options and Settings  
You can customize remote operation settings for OVP (over voltage  
protection) control and TTL shutdown by changing jumper positions on  
the Ethernet/RS-232 Interface card. Refer to the operating manual for  
information on how to use over voltage protection and TTL shutdown.  
OVP Selection  
Over voltage protection (OVP) on the Ethernet/RS-232 Interface is set at  
the factory for remote software operation. When operating the power  
supply in remote mode, you control the OVP trip level using the OVSET  
software command. If you return the power supply to local operation by  
using the REN software command or the front panel LOCAL switch,  
control of the OVP trip level changes from software control to the front  
panel OVP potentiometer. The default OVP trip level is set as 110% of the  
power supply's rated output voltage. See Table 2-10 on page 2–21 for a  
complete list of remote power ON default settings.  
You can isolate the location of OVP control by changing the positions of  
the Local OVP Control jumper J65 and the Remote OVP Control jumper  
J103, both on the Ethernet/RS-232 Interface PCB. The default jumper  
settings allow control of OVP to depend on the operating state of the  
power supply. By physically changing the jumper settings, you can isolate  
the location of OVP control to software control only or front panel control  
only. Table 2-12, “OVP Control Mode Selection” on page 2–24 shows a  
table of jumper settings and OVP programming selection. Refer to Figure  
2-3 on page 2–6 for the location of the jumpers on the Ethernet/RS-232  
Interface PCB. You will need to remove the cover to change any jumpers.  
See “Changing Internal Jumpers” on page 2–8.

TTL Shutdown Polarity  
You can use the Shutdown function to disable or enable the supply's  
output. Disabling the supply using TTL shutdown allows you to make  
adjustments to the load or to the power supply without shutting down the  
power supply. With the Ethernet/RS-232 Interface installed, TTL  
shutdown is activated by a TTL signal to Pin 1 of the user lines connector  
on the interface subplate. The shutdown user line uses a 0-5Vdc TTL  
input with a high signal range of 2.2-5.0Vdc. The current range of the  
shutdown line is 1-10mA. See Figure 2-6, “User Lines Signal Connector  
Circuit Block Diagram” on page 2–27 for a schematic of the user lines  
connector containing the shutdown user line.  
You can select the logic level of the TTL input by changing the J93  
connector on the Ethernet/RS-232 Interface PCB. Table 2-13 shows the  
TTL signal levels for the J93 jumper settings. See Figure 2-3 for the  
location of the J93 jumper on the printed circuit board. You will need to  
remove the cover to change any jumpers. See “Changing Internal  
Jumpers” on page 2–8.

User Signals  
User Lines Connector  
Auxiliary User Lines connector, located on the Ethernet/RS-232 Interface  
rear panel, provides several signals to increase your operating control of  
the supply. These signals are dependent on the operator's design and uses.  
The operation of the user lines connector signal requires that you provide  
external Vcc and ground. Use a standard 8-position telephone jack and  
data cable to connect to the user lines connector. To locate the connector,  
refer to the Ethernet/RS-232 Interface subplate drawing in Figure 2-2 on  
page 2–5. See Table 2-14 for pin descriptions. The user lines connector  
outputs can sink a current of 5mA each. Figure 2-6 on page 2–27 shows  
the portion of the option board schematic which contains the user line  
connector. Use the schematic as a reference when making input or output  
connections.

Installation and Configuration  
User Lines Cable Connection  
Use a standard 8-position telephone jack and data cable to connect to the  
user line connector. Add a ferrite block to reduce radiated emission. The  
one inch square ferrite block with built-in housing clip is packaged and  
shipped with the power supply interface card.  
To install the ferrite block:  
1. Position the block no more than 5 cm (2 in.) from the power supply  
end of the user line connector cable.  
2. Open the ferrite block housing.  
3. Loop the cable through the ferrite block. See Figure 2-7, “User Lines  
Cable with Ferrite Block” on page 2–28.  
4. Close the housing clip.  
The ferrite block ensures that the power supply system meets radiated  
emission requirement 89/336/EEC for CE mark approval. See the power  
supply's operating manual for noise specifications.

Introduction  
This section covers Ethernet/RS-232 Interface programming, including  
an extensive set of device-dependent commands, error codes, and status  
and fault register information.  
 
Operation  
RS-232 Operation  
When the Ethernet/RS-232 Interface card is configured for RS-232 you  
can send and receive data between your power supply and computer,  
relying on bit serial communication. You can use the computer controller  
to issue commands to the power supply for programming, queries,  
calibration, or status. The power supply responds to the complete  
command set of device dependent software commands shown in  
“Command Reference” on page 3–9.  
Ethernet Operation  
When the card is configured for Ethernet, you can send and receive data  
between you power supply and computer via your network. The same  
command set is used for RS-232 and Ethernet. The only difference is  
medium and protocol used.  
Command Syntax  
Manual Conventions  
The manual uses these conventions when displaying command  
information. These characters are not part of the command but are used to  
denote parameters used with the command.  
< > (angle brackets)  
Angle brackets enclose a parameter. Do not include  
the angle brackets in the command line you send to  
the computer.  
/ (slash)  
Separates two alternative parameters. When a slash  
separates two parameters, you can use either  
parameter to achieve the same result.  
Example: <1/ON>  
Entering 1 or ON will achieve the same result.

Command Syntax  
Command Format and Parameters  
The device-dependent language for the Ethernet/RS-232 Interface  
consists of commands and parameters. A command is a one word code  
which either gives instructions to the interface or asks for information  
from the interface. A command may be followed by one or more  
parameters, a short code that changes the state of the power supply or the  
state of the bit register. Table 3-1, “Command Parameters” on page 3–4  
lists the parameters that affect the command set.  
Format:  
COMMAND or  
COMMAND <parameter> or  
COMMAND <parameter>,<parameter>  
You can enter commands in upper or lower case lettering.  
Example: MASK FOLD = mask fold  
Do not further abbreviate command names or parameters.  
Example: MASK FOLD MK FOLD  
MASK FOLD MASK FD  
Use a space between the command and the first parameter. Any  
number of consecutive spaces is treated as one space. Numeric data  
may contain leading spaces. Embedded spaces between digits or  
between a digit and a decimal point are not accepted.  
Example: MASK FOLD = MASK  
VOUT 3.4 = VOUT  
FOLD  
3.4  
4
VOUT 3.4 VOUT 3.  
Use commas between parameters in those commands with more than  
one parameter, and between mnemonic parameters as in the MASK  
and UNMASK commands. Only one comma is allowed and it may be  
preceded or followed by any number of spaces.  
Example: MASK CV, OV, FOLD

Command Syntax  
Command Strings  
If you send more than one command line, separate the commands with a  
semicolon. The semicolon may be preceded or followed by spaces.  
Example:  
ISET 2.0A; VSET 5V  
ISET 2.0A; VSET 5V  
Command Terminators  
Terminators indicate the end of a command string and tell the power  
supply to execute the command. The termination character is CR  
(Carriage Return).  
Format:  
COMMAND <parameter>; COMMAND <parameter>,  
<parameter><CR>  
Order  
You may send commands in any order, keeping in mind that only those  
commands received after a HOLD and before a TRG (trigger) will be  
released by the TRG command. In addition, only these commands  
received after a supply disable (OVP or foldback protection) and before a  
RST (reset) or OUT ON command will be released by the RST command  
or the OUT command. Commands are executed in the order they are  
received.

Table 3-7 Command Reference  
ASTS?  
Asks for the supply’s accumulated status register. The accumulated status register  
stores any bit that was entered in the status register since the accumulated status  
query command (ASTS?) was last used, regardless of whether the condition still  
exists. The accumulated status register has the same bits, weights, and conditions  
as the status register. A bit in the accumulated status register will be set at 1 if the  
corresponding bit in the status register has been 1 (TRUE) at any time since the  
register was last read. See “Accumulated Status, Status, and Fault Registers” on  
page 3–17. The ASTS? query clears the status register.  
Response: ASTS <status mask> where status mask is the decimal equivalent of the  
total bit weights for the operating conditions as listed in the status register.  
AUXA <1/ON>, Controls the AUXA output signal level at rear panel connector Pin 7. Active low.  
<0/OFF>  
Initial value: AUXA 0  
AUXA?  
Asks for the present set value of the AUXA output signal.  
Response: AUXA 0 (OFF) or AUXA 1 (ON)  
AUXB <1/ON>, Controls the AUXB output signal level at rear panel connector Pin 8. Active low.

AUXB?  
Asks for the present set value of the AUXB output signal.  
Response: AUXB 0 (OFF) or AUXB 1 (ON)  
CLR  
Initializes the power supply to its power ON condition. If issued while in local  
mode, CLR will force power supply settings to register default values as in but  
these default settings will not come into effect until the power supply is switched to  
remote mode operation. The CLR commands will clear faults from the fault  
register. CLR will not reset CMODE.  
CMODE<1/ON>, CMODE ON places the power supply into calibration mode for processing  
<0/OFF>  
calibration commands.  
Initial value: CMODE OFF or CMODE 0  
CMODE?  
Asks for the power supply’s calibration mode status.  
Response: CMODE 0 (disabled)  
CMODE 1 (enabled)  
TM-XR9B-01XN  
3–9  
 
Operation  
Table 3-7 Command Reference  
DLY <seconds> Sets a programmable time delay employed by the supply before reporting fault  
conditions. The power supply uses the time delay after receiving a new output  
voltage or current setting via VSET or ISET, or after receiving RST, TRG, or OUT  
ON commands. During the time delay, the power supply disables CV, CC, and  
FOLD conditions from generating faults, preventing possible nuisance foldback if  
the supply momentarily switches modes while changing an output setting.  
Range: 0 to 32 seconds, with 32ms resolution  
Initial value: 0.5 second  
DLY?  
ERR?  
Asks for the setting of the programmable time delay before the supply reports fault  
conditions.  
Response: DLY <seconds>  
Asks for the most recent remote programming error. When the power supply  
detects a programming error, it lights the ERR LED and sets the ERR bit in the  
accumulated status and fault registers. If the error bit has been masked using the  
MASK command, then the ERR bit in the registers will not set. Once an error is  
detected, the remaining portion of the command line is discarded. An error query  
clears the ERR bit in the accumulated status register. See “Error Codes” on page 3–  
19.  
Response: ERR <error number> Example: ERR 0 (if no error)  
FAULT?  
Asks for the state of the fault register. A bit is set in the fault register when a fault  
arises for that condition. Lists the conditions which activate a fault bit. You can use  
the MASK command to disable bits from being set in the fault register.  
When a bit is set in the fault register it also asserts a signal on the Pin 4 user signal  
line. You can tie the Pin 4 fault line signal to the power supply's own External  
Shutdown user line, Pin 1, so that the shutdown signal goes low (active) in the case  
of a user-defined fault.  
The FAULT? query clears bits in the supply's fault register and fault line.  
Response: FAULT <fault mask> where fault mask is the decimal equivalent of the  
total bit weights for the operating conditions as listed in the fault register. See  
“Accumulated Status, Status, and Fault Registers” on page 3–17.  
FOLD  
Sets foldback mode for the supply. Foldback protection disables the power supply  
<2/CC>, <1/CV>, output when the output enters the fold condition. Reset with the RST command.  
<0/OFF>  
Example: Specify FOLD 1 or FOLD CV (Constant Voltage) when you want the  
supply to operate in Constant Current mode and have foldback protection disable  
the output if the supply switches to Constant Voltage mode.  
Initial value: FOLD 0/OFF  
3–10  
TM-XR9B-01XN  
 
Command Reference  
Table 3-7 Command Reference  
FOLD?  
Asks for the supply’s present foldback setting.  
Response: FOLD <mode> where mode is:  
0 (OFF) or  
1 (CV or Constant Voltage mode) or  
2 (CC or Constant Current mode)  
GTL  
Go to local. Returns the power supply to local control. See LLO (Local Lockout).  
See also“Remote/Local Operation” on page 2–20.  
HOLD <1/ON>, Enables or disables voltage/current setting hold mode for the supply. When  
<0/OFF>  
HOLD ON is specified, hold mode is enabled so that all voltage and current  
settings which would normally be implemented by the supply are held until a TRG  
(trigger) command is received. This feature allows you to synchronize the  
operation of several supplies.  
Initial value: HOLD OFF or HOLD 0  
HOLD?  
ID?  
Asks for the present hold mode setting.  
Response: HOLD 0 (OFF or disabled) or HOLD 1 (ON or enabled)  
Asks for the power supply model and the master EPROM version.  
Response: ID <model name><version>  
IDATA  
<Ilo>,<Ihi>  
Calculates and records the slope and offset for programmed current using ILO and  
IHI data. Set CMODE ON before using this command. See also the calibration  
procedures in Chapter 4.  
<Ilo> and <Ihi> are in <current> format.  
IHI  
In response to this command, the power supply sends a programmed current value  
to the output terminal. This value is at the high end of the power supply’s current  
range and is read by an external device connected as part of the calibration  
procedure. Refer to this value as IHI and record it to use as input with the IDATA  
command. Set CMODE ON before using this command. See also the calibration  
procedures in Chapter 4.  
ILO  
In response to this command, the power supply sends a programmed current value  
to the output terminal. This value is at the low end of the power supply’s current  
range and is read by an external device connected as part of the calibration  
procedure. Refer to this value as ILO and record it to use as input with the IDATA

Accumulated Status, Status, and Fault Registers  
Accumulated Status, Status, and Fault Registers  
The Ethernet/RS-232 Interface card uses three separate registers which  
are always active. They are the accumulated status, status, and fault  
registers. You can use the status commands shown in Table 3-6, “Status  
Commands” on page 3–8 to activate the registers. The bit register has  
twelve conditions, each assigned a bit weight. When querying a register,  
the controller returns a response which is the sum of the weights of all  
relevant conditions.  
Example:  
ASTS?  
Query the Accumulated Status register.

WARNING  
Exercise caution when using and servicing power supplies.  
High energy levels can be stored at the output voltage terminals  
on all power supplies in normal operation. In addition,  
potentially lethal voltages exist in the power circuit and the  
output connector of power supplies which are rated at 40V and  
over. Filter capacitors store potentially dangerous energy for  
some time after power is removed.  
Diagnostic LEDs  
This section describes the diagnostic LEDs found on the Ethernet/RS-232  
Interface.  
Computer Operating Properly (COP) LEDs  
The Ethernet/RS-232 Interface provides three diagnostic LEDs, located at  
CR167, CR166, and CR89 on its PCB. Refer to Figure 2-3, “Ethernet/RS-  
232 Interface PCB” on page 2–6, for their locations. At present, these  
LEDs turn on to signal COP events for the interface's microprocessors.  
Issue a RST (reset) command to turn off the diagnostic LEDs.  
The green COP LED at circuit designation CR167 indicates that the  
Ethernet/RS-232 Interface microprocessor successfully recovered from a  
timeout error due to a communications bus error. The event is transparent  
to the RS-232 communications line which continues to function normally.  
The red COP LED at CR166 indicates that a transparent restart caused by  
noise in the master processor circuitry has occurred.  
The red COP LED at CR89 indicates that a transparent restart caused by  
noise in the slave processor circuitry has occurred.

Introduction  
WARNING  
Exercise caution when using and servicing power supplies.  
High energy levels can be stored at the output voltage terminals  
on all power supplies in normal operation. In addition,  
potentially lethal voltages exist in the power circuit and the  
output connector of power supplies which are rated at 40V and  
over. Filter capacitors store potentially dangerous energy for  
some time after power is removed.  
You can calibrate the interface in either Ethernet or RS-232 mode by  
adjusting the signal levels on the interface card so that they correspond  
to the expected signal levels on the power supply's main assembly. You  
may need to recalibrate the interface if you replace parts either on the  
interface board or on the main power supply board, or if the unit falls  
out of specification due to component aging drifts.  
 
Calibration  
You can calibrate the Ethernet/RS-232 Interface for:  
Voltage program  
Voltage readback  
Current program  
Current readback  
Overvoltage protection  
The following equipment will be required to accurately calibrate your  
unit:  
Digital Voltmeter, 5 1/2 digit, 0.1% accuracy or better, with test leads  
Current sensing shunt resistor, rated for 150% of maximum output  
current, 0.25% accuracy or better  
Connection wires rated for the unit's maximum output current and  
voltage  
A network ready, or RS-232 equipped computer to send the  
calibration commands to the unit  
Calibrate the unit according to the following procedures, referring to  
“Command Reference” for more information about the calibration  
commands used.  
The calibration procedures in this section are designed to be performed at  
an ambient temperature of 25°C ± 5°C.

1. Disconnect all loads from the power supply.  
2. Ensure that jumper J65 on the interface PCB is CLOSED to enable  
remote OVP calibration (Jumper J65 is closed at the factory). See  
Figure 2-3, “Ethernet/RS-232 Interface PCB” on page 2–6 for the  
location on the PCB of jumper J65.  
3. Activate calibration mode by sending command CMODE ON or  
CMODE 1 to the power supply.  
4. Send the command OVCAL to the power supply. The ADDR LED  
will light during OVP calibration. Calibration is complete when the  
ADDR LED turns off. This may take a few minutes.  
5. Use the OVSET, OVSET?, and VSET commands to trip the OVP  
level, confirming that the calibration was successful. When you trip  
the OVP level, the red OVP LED will light and the voltage will drop  
to zero. Send the command RST to clear the OVP condition. Refer to  
the OVP program accuracy specification in Appendix A.  
6. Turn off calibration mode by sending the command CMODE OFF or  
CMODE 0 to the power supply.
