Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
WARNIN
WARNIN
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance
equipment must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must
ensure that the output power lines are labeled properly as to the safety hazards and that any
inadvertent contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary
sales organizations can accept any responsibility for personnel, material or inconsequential injury,
loss or damage that results from improper use of the equipment and accessories.
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.

FEATURES, FUNCTIONS, AND
1.1 INTRODUCTION
This manual covers the M130 and M131 Remote Programming Ethernet Interface
Options for the DLM600 Series and the DCS Series power supplies. The M130
(master interface configuration) and M131 (slave configuration) options enable you
to operate your Sorensen power supply from a computer via Ethernet IEEE-802.3 or
RS-232 communication protocols, or with SCPI-compatible language, allowing full
remote programming control and monitoring of your power supply. The M130 can
control up to 30 auxiliary (slave) power supplies
SECTION 1
SPECIFICATIONS
In addition to controlling power supplies configured with the M131 (Ethernet) slave
option, the M130 master can control power supplies configured with the M85
(GPIB/RS232) slave option, which uses the same RS485-based Extended Interface
Bus (EIB) for master/slave control; whereas, a GPIB master (M9x) can control only
GPIB slaves (M85). This means that a single Sorensen DLM600 or DCS power
supply configured with the M130 option, can control any Sorensen power supply
(DLM600, DCS 1k, DCS 1.2k, DCS 3k), in any combination of M131 and/or M85
slave configuration options, up to as many as 30 power supplies total.
A final important point is that the M130 / M131 Ethernet options are
eXtensions for Instrumentation) class C compliant. LXI™ is an instrumentation
platform based on industry-standard Ethernet technology designed to provide ease
of integration by modularity, flexibility and performance.

SECTION 2
CONFIGURATION
The M130 is installed into the supply at the factory. Use the Setup Procedure described below
to configure the M130 for your system and application.
2.1 SETUP PROCEDURE
There are four methods of setting the IP address of the unit, each of which is
described in the subsections that follow:
• Set an IP address through DHCP (Primary default).
• If DHCP is not available, the unit can assign itself an IP address in the Auto-IP
(dynamic link local addressing) range (Secondary default).
• Use the serial communications port to manually assign an IP address.
• Set the IP address through the Web page interface.
NOTE: The M130 Ethernet Option has been designed and tested to be fully compatible
with Microsoft Internet Explorer 6.0. This is the only browser supported by Elgar
Electronics Corporation (EEC) in its Ethernet-based products. Earlier versions of
Explorer (or browsers by other companies) may or may not work correctly, and as
such, are not supported by EEC.
2.1.1 M130 NETWORK SETUP USING DHCP
Before beginning this procedure, get access to the DHCP server or see the network
administrator to get the IP address assigned to the power supply.
NOTE: The power supply is VXI-11 compliant, so even without access to the DHCP
server, it is still possible to discover the IP address assigned to the power supply
with programs such as Agilent’s I/O Library Suite or National Instrument’s NI-VISA.
1. Start with the power supply in the power-off state.
2. Connect a RJ-45 network cable from the power supply to the network with the
DHCP server.
3. Power on the power supply and allow the power supply to perform its
initialization.
M130/M131 Programming Manual 2-1
Configuration Sorensen Ethernet Option
4. Identify the IP address assigned to the power supply by accessing the DHCP
server, asking your network administrator, or discovering it with a VXI-11
compliant discover program.
5. The M130 Ethernet hardware is now configured. Open your Web browser and
enter the IP address of the power supply to view the Home page of the power
supply.
Figure 2-1. Power Supply’s Home Page (DLM600 Series shown here)
2.1.2 M130 (MASTER) NETWORK SETUP USING AUTO-IP
For this method, use a VXI-11 compliant discovery program such as Agilent’s I/O
Library Suite or National Instrument’s NI-VISA to discover the IP address assigned to
the power supply. The power supply will assign itself an IP address in the IP address
range from 169.254.0.1 to 169.254.255.254 with a subnet mask of 255.255.0.0.
NOTE: When connecting your Sorensen Master unit to a network, Elgar strongly
recommends using Linksys® hubs or switches, which have undergone extensive
compatibility testing with the M130 interface.
1. Start with the power supply in the power-off state.
2. Connect a crossover cable from the power supply directly to your PC.
3. If the PC is already configured to obtain an IP address automatically, skip to
Step 4. Otherwise:

2.4 PROGRAMMING VIA ETHERNET
2.4.1 COMMUNICATION METHODS
With the M130 option, there are four basic methods to communicate with the power
supply from a PC:
• raw socket interface, sending delimited strings (default delimiter is
<LineFeed>)
• application program that utilizes VXI-11 Discovery protocol
• Web browser and the internal Web server, with scripting of Java applets
enabled
• RS232C serial interface
2.4.2 RAW SOCKET INTERFACE
The essential components of communicating via a raw socket interface are the
socket number, IP address and command delimiter. The default values are: socket =
9221, IP address = 192.168.0.200 (when static IP is enabled), and delimiter = line
feed <LF>. All of these items may be changed either via the Web browser (see
CONFIGURATION, p.
2-16) or RS232C interfaces (see SCPI command section).
IP
For convenience and to comply with the proposed LXI™ standard, the VISA
resource name is available on the home page of the power supply’s Web server.
2.4.3 VXI-11 PROTOCOL
With programs such as Agilent’s I/O Library Suite, or National Instrument’s NI-VISA,
the VXI-11 protocol allows the power supply to be easily configured in a test system.
2.4.4 WEB SERVER
To communicate with the power supply via the built-in Web server, open a supported
Web browser (Internet Explorer 6.0 or higher) and type the IP address of the power
supply in the “Address” field. Tap the
Ethernet Web page interface.
Note: To ensure proper functionality on your Web browser, Sun Microsystems’ Java
Runtime Environment must be installed on your PC. Visit www.java.com to
download. Also, set your Web browser’s Security to enable scripting of Java
applets. (In the Tools menu, select Internet Options… and click the Security

Ethernet Web Pages, Overview
The layout of each of the Web pages includes the banner with the heading,
“Sorensen DLM (or DCS) Power Supply Interface” along with the device name
below and a LOGIN button to the right. Below the banner are six tabs, each linked
to its corresponding page. On each page is a title line (title matches tab name). In
the title line is an area that frequently displays informational messages as you use
the Web interface.
When navigating to the Ethernet Web pages by clicking their tabs, you will find
that only two of the pages may be accessed without logging in: HOME (default)
and SLAVE INFO; you must log in (click LOGIN) before tabbing to the other
pages, which allow access by permission only: FULL (Administrator), RW
(Read\Write), or R (Read).
• FULL permissions users have access to all pages and all channels and
may configure the interface, set and change security settings, allocate
channels, control the output of the power supply, send commands, etc.
• RW permissions users may access all pages except SECURITY, and may
read and control the output of the power supply for only the channels
allocated to them. They are not authorized to make changes on the IP
CONFIGURATION page.
• R permission users may read information related only to the channels
allocated them, and cannot make any changes or control the output.
Once you have logged in, the LOGIN button becomes a LOGOUT button.
Note: There are few differences between the DCS interface and the DLM
interface: their titles and device names in the banner (see
Figure 2-13), their specifics in the Home page (see Figure 2-15 and Figure
2-16), and the front panel lockout button in the Settings page (see

you select Obtain an IP Address Automatically and
you check Auto IP Enabled in TCP/IP Primary
Configuration, the system will not try the Secondary
Configuration.
To enable: Click in the box to check; click again to uncheck so
that it is no longer enabled.
Example TCP/IP Configurations:
Primary: Use a Static IP Address
Secondary: Obtain an IP Address Automatically (DHCP)
At power-up the power supply will assign itself the configured static IP address. If
no other device is using the IP address, the power supply continues with that
static IP address. If some other device is using that address, the power supply
will move to Secondary and attempt to acquire an IP address from a DHCP
server repeatedly until it gets an address.
Primary: Use a Static IP Address
Secondary: Obtain an IP Address Automatically (DHCP) and AutoIP
Enabled
At power-up the power supply will assign itself the static IP address. If no other
device is using the IP address, the power supply continues with that static IP
address. If some other device is using that address, the power supply will move
to secondary and attempt to acquire an IP address from a DHCP server. If it
cannot find a DHCP server to assign an address, it will assign itself a link-local
address. If no other device is using that link-local address it will use it for 5
minutes minimum. At that time, if it is already in communication with some other
device, it will hold onto that link-local address until the communication is finished
and then retry DHCP. Then, if DHCP is not available, the power supply will revert
to the last successful link-local address for another 5 minutes minimum.

2.4.5 TROUBLESHOOTING
Resetting IP Configuration
Either press and hold in the IP reset switch (S2) on the rear panel until the green
NET LED flashes (this could take 5 or more seconds), which resets the Primary
configuration to DHCP and AutoIP Enabled (and ignores Secondary
configuration), or send the SCPI command, SYST:NET:IP xxx.xxx.xxx.xxx
through one of the following: the RS-232, the Server, or VXI-11. This sets the
primary configuration to Static IP, and the secondary configuration is left where it
presently is.
Cannot Establish Communication
Use RS232 port. Note 19.2k baud rate at J6.
Query IP address with the SCPI command, SYST:NET:IP?
Query the MAC address with the SCPI command, SYST:NET:MAC?
For Slave (M131) communication issues, check the slave unit address switch
setting.
Communication Established, but No Power Supply Response
Check SCPI string for errors (use the command SYST:ERR? to check response
from unit)
Web Page Does Not Come Up
Check IP address; validate your SUBNET Mask.
Verify that both your computer and the power supply are on the same network.
If using a direct connection with a crossover cable, verify the PC is set to static IP
address on the same network.
Observe the indicator LED on Ethernet port (J11) for activity. The NET LED (at
rear panel center, near IP reset switch) will be lit when communication is
established.
Lost/Forgot Password
If you are a user, contact the Administrator of the power supply network to modify
your password.
If you are the administrator, the only way to recover is to press and hold the IP
reset switch on the rear panel until the Green NET LED blinks (this could take
five or more seconds). The administrator User Name and password will be
restored to factory defaults, as will the IP Address, the IP Addressing Mode, Ping
Enable, SUBNET Mask, Host name, and Description String. All other defined
user names and passwords are not affected by the reset operation.

3.1 INTRODUCTION
The following sections describe the operation of the M130 by remote
programming using the M130 IEEE-488.2 and SCPI command sets. The supply
IEEE488.2 and SCPI command sets provide programming, query, and status
commands that facilitate remote control of the power supply.
SECTION 3
IEEE 488.2 AND SCPI
COMMAND OPERATION
3.2 IEEE-488.2 REGISTER DEFINITIONS
The M130 supports the IEEE-488.2 and SCPI 1995.0 status reporting data
structures. These structures are comprised of status registers and status register
enable mask pairs. The following sections describe these pairs.
3.2.1 SCPI STATUS BYTE
• To read the SCPI Status Byte status register, either send the *STB?
command or issue a GPIB or Ethernet serial poll. To clear the Status
Byte status register, send the *CLS command.
• To configure the supply to request service from the Ethernet controller,
set the appropriate bits in the Service Request Enable (SRE) register.
The SRE register has the same bit pattern as the SCPI Status Byte.
• To modify the SRE register, use the *SRE <mask> command; to read it,
use the *SRE? command. For example, if the SRE register is set to 0x10
(MAV), then when the supply has a message available, the Status Byte
register will contain 0x50 (RQS and MAV). See
Table 3-1.

Not used.
Protection Event Status flag. Indicates the selected protection
event occurred.
Error/event queue message available. Set when any error/event is
entered in the System Error Queue. It is read using the
SYSTem:ERRor? query.
Questionable Status flag. Indicates the quality of the current data
being acquired. This bit is not used.
Message available (MAV). Indicates a message is available in the
GPIB or Ethernet output queue. Cleared after the GPIB or Ethernet
output buffer is read.
Standard Event Status Register (ESR). Summary bit for the ESR.
Set when any of the ESR bits are set and cleared when the ESR is
read.
Request Service flag (RQS) for serial polling or Master Summary
Status (MSS) in response to *STB? If service requests are enabled
(with the *SRE command), this bit represents the RQS and will be
sent in response to a serial poll, then cleared. If RQS is not
enabled, the bit represents the MSS bit and indicates the device
has at least one reason to request service. Even though the device
sends the MSS bit in response to a status query (*STB?), it is not
sent in response to a serial poll. It is not considered part of the
IEEE-488.1 Status Byte.
Operation Status flag. Indicates the current operational state of the
unit. This bit is not used.
3.2.2 STANDARD EVENT STATUS REGISTER (ESR)
• To read the Standard Event Status Register (ESR), use the *ESR?
command.
• To clear the ESR, either read this register or issue the *CLS command.
• To enable corresponding ESR bits to be summarized in the summary bit
of the SCPI Status byte, issue the *ESE (Standard Event Status Enable
Register) command.

5 0x20 Command Error (e.g., syntax error)
6 0x40 User Request - not used
7 0x80 Power On
3.2.3 PROTECTION CONDITION AND PROTECTION EVENT STATUS REGISTERS
These two registers have the same bit meanings, but they differ in function.
• To read the Protection Condition, use the STAT:PROT:COND?
command. This command gives the present status condition of the
power hardware, so the data is not latched. It is a polling register.
• To read the Protection Event Status, use the
STATus:PROTection:EVENt? command. To clear the Protection Event
Status Register, either read this register with the *RST command, or
issue the *CLS command.
• To set bits in the Protection Event Status Register, you must first set the
corresponding bit in the Protection Event Status Enable Register and the
corresponding event must occur.
• To set the Enable Register, issue the STATus:PROTection:ENABle
<mask> command. The status is then latched and will remain in that
state until it is read or cleared due to some command action. Then use
the STATus:PROTection:ENABle? query to read the Enable Register.

3.2.4 OPERATION STATUS AND QUESTIONABLE STATUS REGISTERS
The Operation Status and Questionable Status Registers will always return 0
when queried. The Operation Status Enable and Questionable Status Enable
Registers can be programmed and queried to allow SCPI compatibility but have
no effect on the Operation Status and Questionable Status Registers.
3.2.5 ERROR/EVENT QUEUE
The supply maintains an Error/Event Queue as defined by SCPI. The queue
holds up to 10 error events.
To view the error events, use the SYSTem:ERRor? Query command, which
reads in a First In/First Out (FIFO) manner. The read operation removes the
entry from the queue. The *CLS command clears all entries from the queue.
The following error codes are defined in the SCPI 1995.0 specification and are
supported by the M130. Error codes are in the range of [-32768, 32767]. SCPI
reserves the negative error codes and 0, while error codes greater than 0 are
device-specific errors.

Isolation relay must open first
An attempt to change the state of the polarity relay was made while the
isolation relay was closed. First open the isolation relay; then change the
state of the polarity relay.
Voltage sign mismatched polarity relay state
The algebraic sign on the voltage of a voltage programming command,
such as SOUR:VOLT <volt>, did not match the state of the polarity relay,
so the voltage command was ignored. For example, if the polarity relay is
in the positive voltage position (normal output voltage position), the
command SOUR:VOLT –5 will cause this error. Conversely, if the polarity
relay is in the negative voltage position (inverted output voltage position),
the command SOUR:VOLT 5 will cause this error.
Note that programming Over Voltage Protection with a mismatched
algebraic sign also can cause this error.
No channels setup to trigger
An attempt was made to trigger the M130 using the TRIG:TYPE <1|2|3>
command when there are no armed trigger settings. This error is not
generated when the GET is received, even when there are no armed
trigger settings.
GPIB or Ethernet GET not allowed during message
The GPIB or Ethernet G(roup) E(xecute) T(rigger) multiline command was
errantly generated by the system computer while or very shortly after a
message is or was sent. Give a few milliseconds after a message is sent
before attempting a GET; and never send a GET during a message
transfer over the GPIB or Ethernet.

GPIB or Ethernet IFC caused warm boot
This error relates to the GPIB or Ethernet IFC signal, and is available only
in association with a proprietary command.
Hardware watchdog warm boot
Caused by a hardware fault either in the power supply proper, or on the
M130. One possible explanation might be that the mains power to the
supply was interrupted for a short but sufficient time to cause the M130
processor to reset and re-boot. Also, it might be possible to generate this
error by a very momentary power-off through the front panel power switch.
Foreground watchdog warm boot
The internal firmware on the M130 found an internal error condition that
halted processing; to force resumption of processing, a warm boot is
required.
Unexpected warm boot
The M130 GPIB or Ethernet-side processor experienced a warm boot that
was unexpected, and it may indicate an internal crash of the M130
processor.
Incompatible unit type
This error is not used. It cannot occur.
Incompatible unit version
This slave does not support user defined initialization values nor ramping;
its firmware is too old a version to do so. Slave #n provides its firmware
version number as the last number on the response from the *IDN[n]?
query command.
Incompatibility error
This error is not used. It cannot occur.
No error
The error queue is empty.
Syntax error
An unrecognized command or data type was encountered.
Parameter not allowed
More arguments than expected were received.
Invalid string data
Incorrect password. Manufacturer, model, or serial number string was
more than 16 characters. Invalid mnemonic.
Invalid block data
The expected number of data values was not received.
Execution error
An error/event number in the range [-299,-200] indicates that an error has
been detected by the instruments execution control block. The occurrence
of any error in this class shall cause the execution error bit (bit 4) in the
Event Status Register to be set. An execution error can be the result of:
• A <program data> element out of range, such as programming 35 volts
in a 33 volt device.
• A command could not be executed due to the current condition of the
device.
Command protected
Attempted to store calibration values to EEPROM without unlocking.

Queue overflow
The error queue can contain up to 10 entries. If more than 10 error/event
conditions are logged before the SYSTem:ERRor? query, an overflow will
occur; the last queue entry will be overwritten with error -350. When the
queue overflows, the least recent error/events remain in the queue and the
most recent error/events are discarded.
Communication error
Communication to a channel was disrupted.
3.2.6 SERIAL POLL OPERATION
Performing a serial poll will not modify the Status Byte other than to clear the
RQS (bit 6) for a supply requesting service. Queries affecting the Status
Registers and subsequent serial poll are described below:
• *STB? clears the Status Byte
• *ESR? clears the ESR and bit 5 of the Status Register
• SYSTem:ERRor? clears bit 2 of the Status Register if the queue is empty

3.3.3 CONVENTIONS
SCPI uses the conventions where optional commands and parameters are
enclosed by “[ ]”. Additionally the shorthand version of a command is indicated
by capital letters. The optional parameter “[n]” selects the auxiliary channel
number (power supply) being commanded. If “[n]” is not specified, the default
master channel 1 is automatically selected. Channel 1 selects the master unit
and channels 2-31 select an auxiliary unit attached with the M131 option.
Selecting the global channel 0 is allowed only for the TRIGgerred[n] commands.
For example,
SOURce[n]:VOLTage[:LEVel][:IMMediate][:AMPLitude] 120.0
can be written as
SOURce[n]:VOLTage 120.0 // for any channel
or
SOUR:VOLT 120.0 // for default master channel 1
3.3.4 QUERIES
The query syntax is identical to the command syntax with a “?” appended and
no additional parameters/arguments following. For example, to query the
programmed voltage, send the string: SOURce:VOLTage?. A subsequent
device read will return a value such as “33.000”. For Ethernet, all queries are
terminated with a carriage return. For GPIB controllers that require termination
characters, all queries are terminated with a carriage return and line feed (0x0D
0x0A). When the supply has nothing to report, its output buffer will contain two
ASCII characters: a carriage return and linefeed (in decimal the values are:
<13><10>).

*Note: For DLM600 Series firmware versions 1.07 and later, the algebraic sign of the
voltage value must match the state of the polarity relay, otherwise an error message
will be generated, and the voltage command will be ignored. If the voltage value
entered is positive, then the polarity relay must be in the NORM state (query the
state of the polarity relay using the OUTP:POL? query command). If the voltage
value entered is negative, then the polarity relay must be in the INV state. For
DLM600 Series firmware versions 1.06 and earlier, the algebraic sign caused the
3-20 M130/131 Programming Manual
Sorensen Ethernet Option IEEE 488.2 and SCPI Command Operation
polarity relay to change automatically to the matching state. This automatic change
in the polarity relay state is no longer supported in firmware versions 1.07 and later.
To change the state of the polarity relay, use the OUTP:POL <INV | norm>
command (when the isolation relay is open). For DCS Series supplies, the polarity
relay still automatically follows the algebraic sign.
3.8.3 THE RAMP FUNCTION
The ramp function allows the user to transition from one voltage or current to
another linearly in a specified time period (100 ms - 99 sec with 100 ms
programming resolution). The ramp-upon-trigger function may be used to
program different ramping parameters for several units then trigger them all to
begin their ramps at the same time. A unit may ramp only voltage or current, not
both at a given time. For example, SOUR:VOLT:RAMP:TRIG 1 1 followed by
SOUR:CURR:RAMP:TRIG 2 2 will cause the unit to ramp only the output
current to 2 amps in 2 seconds upon the TRIG0:RAMP command.
Voltage ramping to a higher voltage requires a programmed current of at least
20% of the full scale value. Settings less than 20% will significantly lengthen the
ramp time due to charging of the large capacitance in the output section of the
power supply.
Voltage ramping to a lower voltage requires an appropriate resistive load. The
discharge rate of the large capacitance in the output section of the power
supply, plus other user capacitance, significantly lengthens the ramp time.
Current ramping requires an appropriate resistive load.
Note: On DCS and PRO-T models, the Reading of Voltage or Current during Ramping will
extend Ramp Time.

SYST[N]:LOCAL <ON|OFF> is a special
purpose programming command that may be
used to cause source [N] to be set to the local
state or to the remote state. This command has
two noteworthy circumstances under which it
may prove necessary. The first case involves
using RS232 to communicate with the supply,
since the normal GPIB or Ethernet mechanisms
for transition between local and remote and
back again do not exist when using RS232. The
other case is when the REMOTE/LOCAL switch
S1-1 is placed in the ON position—thereby
disabling the GPIB or Ethernet mechanism for
transition from remote to local. The
SYST[N]:LOCAL ON command provides a
means for the system computer to force source
[N] to the local state. Also, the
SYST[N]:LOCAL? query command is available
to examine the local-remote state of the supply.
And the command SYST[N]:LOCAL OFF may
be used to force supply [N] to the remote state.

Description
The SYST[N]:LOCLOUT <0|1|OFF|ON>
command provides a means of controlling the
local lockout functionality that is an alternative to
the low level GPIB or Ethernet LLO command. A
source number may be specified with this
command, thereby allowing selective disabling
of the front panel of a selected source.
In contrast, using the GPIB or Ethernet LLO low
level command causes the master supply, and
all attached online M131 slaves, to be placed
into the local lockout state. To place the master
and all online M131 slaves into the local lockout
state using the SYST[n]:LOCAL:LOCKOUT
command, specify the source number of 0.
To place only one slave into the local lockout
state, specify that slave in the command. For
example, if the slave is source 3, use the
command: SYST3:LOCAL:LOCKOUT 1.
Returns the baud rate for the slave.
Forces slave to jump to its boot loader.

CALIBRATION
WARNING
Please refer to the power supply manual for further information before performing
calibration procedures. Qualified personnel who appropriately deal with attendant
hazards must perform calibration. If calibration is not performed properly,
functional problems could arise, requiring that the supply be returned to the
factory.
4.1 INTRODUCTION
The supply is calibrated to adjust internal signal levels to correspond to the expected
supply output signal levels. You must perform the calibration procedures if the power
supply’s programming or readback performance falls out of specification due to
component aging drifts. Refer to your power supply manual to find the required
calibration interval. The supply also is calibrated for output voltage programming,
output current programming, output overvoltage protection programming, voltage
readback, and current readback. There are 10 calibration factors (four measurement
and six output).
The calibration procedures in the following sections are designed to be performed at
ambient temperature of 25°C +
load for at least 30 minutes.
The following test equipment is required in addition to the computer system to
complete the following calibration:
• 6-digit digital voltmeter (DVM)
• current shunt rated for 110% of full output current
5°C, after the unit has had a stable output and a stable

10. Once calibration is completed, new values for Last Calibration Date and Next
Calibration Date may be entered. See Section
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 on power supplies that are rated at 60V and over. Filter
capacitors store potentially dangerous energy for some time after power is
removed.

OPERATION WITH M131 OPTION
5.1 INTRODUCTION
The following sections describe the operation of the power supply with the M131
option and how to configure the option for your application.
The M131 option enables you to use your power supply as an auxiliary unit. The
master unit would be a power supply with the M130 interface option. The auxiliary unit
or units share the Ethernet address or RS-232 interface with the master unit. Up to 30
auxiliary units can be controlled by the master unit.
This option can be used with the DLM600 and DCS 1kW and 3kW supplies and
supports the SCPI language.
SECTION 5
5.2 CONFIGURATION
The S1 DIP switch is accessible from the rear panel. It allows configuration of the
M131 for auxiliary operation.
DLM600 and the DCS 3k power supplies with the M131 option, configured as an

Note: Channel numbers 0 and 1 are invalid for any auxiliary device, because the M130
implementation of the SCPI language reserves channel 0 for the “global” address to
address all channels, and it reserves channel number 1 as the default number for the
master channel.
Set channel number for unit in binary:
Binary 1 ON
Binary 2 ON
Binary 4 ON
Binary 8 ON
Binary 16 ON
(Channels 0 and 1 see note below.)

Binary 4 OFF
Binary 8 OFF

5.3 SYSTEM INSTALLATION
Follow the steps below, illustrated in Figure 5-3, to install the configured M131 into
your system:
1. Configure the M131 as described in the Configuration section above.
2. Connect the master unit’s RS-485 output connector, J2, to the auxiliary unit’s RS485 input connector, J1, using the modular cable.
3. If there are additional auxiliary units, connect the installed auxiliary unit’s RS-485
output connector, J2, to the additional auxiliary unit’s RS-485 input connector, J1,
using the modular cable.
4. Connect the 120 ohm resistive termination assembly to the last auxiliary unit’s J2
connector.
5. Connect power to the system, power it up, and verify that the green REMOTE
LED on the front panel is ON.
6. Test the link by communicating with the auxiliary unit from the master unit, using
the *IDN[n]? command. Note that [n] is the channel number—for example,
*IDN2? calls channel 2. (In response to this string, the system returns the power
supply model number and the firmware version.)
NOTE: The slave baud rate is 9600.

5.5 PROGRAMMING THE M131 UNIT (EXAMPLE)
The following example programs the M131 unit to:
• Turn on
• Initialize to 2 VDC, at 1A
• Set overvoltage protection level at 3 VDC
• Verify proper power-on initialization
• Save and store changes.
// Use SYST:ERR? after each command to verify no programming errors.
// turn on the unit.
*CLS // clear the unit to its power on default settings.
*RST // reset the unit.
CAL[n]:INIT:CURR 1.0 // set power-on initial current to 1.0A.
CAL[n]:INIT:CURR? // confirm power-on initial current setting.
CAL[n]:INIT:VOLT 2.0 // set power-on initial voltage to 2.0V.
CAL[n]:INIT:VOLT? // confirm power-on initial voltage setting.
CAL[n]:INIT:VOLT:PROT 3.0 // set power-on initial overvoltage protection to 3.0V.
CAL[n]:INIT:VOLT:PROT? // confirm power-on initial overvoltage protection setting.
CAL[n]:UNLOCK “6867” // unlock nonvolatile memory for calibration value storage.
CAL[n]:STORE // store the calibration values in nonvolatile memory.
CAL[n]:LOCK // lock nonvolatile memory for calibration value protection.
// cycle power to unit.
// note voltage is initialized to 2.0 VDC via front panel.
SOUR[n]:CURR? // confirm power-on initial current setting.
SOUR[n]:VOLT? // confirm power-on initial voltage setting.
SOUR[n]:VOLT:PROT? // confirm power-on initial overvoltage protection setting.
