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/use r 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.

The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.

FEATURES, FUNCTIONS, AND

1.1 INTRODUCTION

This manual covers the M130 and M131 Remote Programming Ethernet I nterface
Options for the DLM600 Series and the DCS Series power supplies. The M130
(master interface configuration) and M131 (slave configuration) opt ions enable you
to operate your Sorensen power supply from a computer via Ethernet IEEE-802.3 or
RS-232 communication protocols, or with SCPI-compat ible 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 ar e
eXtensions for Instr um ent ation) class C compliant. LXI™ is an instrum ent at ion
platform based on industry-standard Ethernet technology designed to provide ease
of integration by modularity, f lexibility and perform anc e.

SECTION 2

CONFIGURATION

The M130 is installed into the supply at the factory. Use the Setup Procedur e described below
to configure the M130 for your system and applicat ion.

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 ass ig n it s elf 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 correct ly, 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 t he 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 t he 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 Sorens en Master unit to a network, Elgar strong ly

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 com municate 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 comm unicat ing via a raw socket interface are the
socket number, IP address and c om m and delimit er . 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 item s m ay be chang ed eit her via the Web browser (see IP
CONFIGURATION, p. 2-16) or RS232C interfaces (see SCPI com m and sec t ion) .

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 Libr ar y Suite, or Nat ional 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 s er ver, open a suppor ted
Web browser (Internet Explorer 6.0 or higher) and type the I P address of the power
supply in the “Address” field. Tap the
Ethernet W eb page interface.

Note: To ensure proper functionality on your Web browser, Sun Microsystems’

Java Runtime Environment must be installed on your PC. Vis it
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 tab. At the bottom of the Security window click Custom
level…; in the Reset custom settings drop-down, select Medium and click
Reset and then OK).
