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 simultane ously. From the factory,

the instrument wil l be configured for Ethernet communication. Therefore you should only need to follow these instr uctions if you are switching over to RS-232, or back to Ethernet. To switch between the two configuration s, you must change internal jumpers on the interfac e card. See “Changing Internal Jumpers” on page 2–8. Also refer to Ta ble 2-2 and Figure 2-3 on page 2–6 to locate the corre sponding jumpers.

Table 2-5

Jumper RS-232 Ethernet

J3 1-2 2-3 J4 1-2 2-3 J5 1-2 2-3 J6 1-2 2-3

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 Selectio n” on page 2–18,

“Flow Control Selection” on page 2–19 and “Remote/Local Mode Startup” on page 2–20 for m ore detailed information on how to

reconfigure these settings.

Jumper positions for Ethernet or RS-232

Note: If you are switching the interface card back to Ethernet it is

recommended to se t the baud rate to 9600, turn flow control off, and have the unit power-on in remote m ode (these are the default settings).

2–12 TM-XR9B-01XN

Ethernet Communications

Ethernet Connection

There are two options for controlling your XFR power supply via

Ethernet - "Connecting to a Networ k" 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 inte rface card (NIC). This bypasses the need for an existing network.

Connecting to a Network

All that is requir ed to connect your XFR to a network is a straig ht 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 crossover 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.

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 inst ru ment will al ready have an IP addr ess. If not, y ou 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 tha t you can access the instrument via its web server, and for when you start communi cating with the power supply.

2–14 TM-XR9B-01XN

Configuring Ethernet Bridge

The Ethernet/RS-232 Interface card has an Ethernet Bridge that converts the ethernet pa ckets to serial data signals for processing by the embedded microcontroller. The Ethernet Bridge must be properly configured for serial communicati ons with the microcontroller. For example, settings on the Bridge, such as Baud Rate and Flow C ontrol, must match the jumper settings on the interfa ce board.

There are two ways to gain access to the configuration menu for the Ethernet Bridge. One is to run the Setup program tha t is available on the Software CD. This program will find your instrument and allow you to configure it by clickin g on th e instr ument ’ s I P ad dress. You will the n n eed 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 ope n up a web browser like Internet Explorer, and type in the IP addr ess for the instrument. Again, you will be asked for the username and password. Once you have accessed the configuration page, follow these steps for prope r setup.

1. Click Configuration > Serial Port, and ensure that the foll owing

settings have been selec ted:

• Baud Rate: 9600

• Data Bits: 8

• Parity: None

• Stop Bits: 1

• Flow Control: None Click Apply onc e you have finished a djusting the above settings.

Installation and Configuration

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 ha ving t o de velop TCP/IP based ne twork applic ations. Inst alle d on a network-enabled PC, RealPort® cre a tes a virtual COM port. As such, your applica tion still thi nks it is working with a real s erial port, such as COM1. When the application sends data to this ser ial 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 appe ars, click Digi RealPort ®.

4. Follow the on-screen instructions for proper installation.

Note: RealPort® drivers for UNIX syst ems are available . Contac t 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® drive r for your instrument.

Additional User Options and Settings

You can customize rem ote operation settings for OVP (over voltage protection) contr ol 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 pro tection and TTL shutdown.

OVP Selection

Over voltage protection (OVP) on the Ethe rnet/RS-232 Interface is set at the factory for remote soft ware 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 outpu t 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 posit ions 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 contr ol of OVP to depend on the operating state of the power supply. By physically ch anging th e jumper sett ings, you can i solate the location of OVP contr ol to soft ware contr ol on ly or fr ont panel con trol only. Table 2-12, “OVP Control Mode Selection” on page 2–24 shows a table of jumper settings and OVP programmin g selection. Refer to Figure

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 ac tivated by a TTL signal to Pin 1 of the user lines connector on the interface subpla te. 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, “Us er Lines Signal Connector

Circuit Block Diagram” on page 2–27 for a schematic of the user lines

connector contain ing the shutdown user line. You can select the logic level of the TTL input by changing the J93

connector on the Ethernet/RS-232 Int erface PCB. Table 2-13 shows the TTL signal levels for the J93 jumper set tings. See Figure 2-3 for the location of the J93 jumper on the printe d circ uit 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 c onnector, located on the Ethernet/RS-232 Inte rface rear panel, provides sever al 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 subpla te 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 sche matic which contains the user line connector. Use the schematic as a reference when making input or output connections.

Introduction

Operation

This section covers Ethe rnet /RS-232 Interf ace programming, including an extensive set of device-dependent commands, er ror codes, and status and fault register inf ormation.

Operation

RS-232 Operation

When the Ethernet/RS-232 Interface ca rd is confi gured for RS-232 you can send and receive data between your power supply and computer , relying on bit serial co mmunication. You can use the computer controller to issue com mands to the power supply for programming, queries, calibration, or status. The power supply responds to the complet e command set of device dependent softwa re commands shown in

“Command Reference” on page 3–9.

Ethernet Operation

When the card is config ured 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 protoc ol used.

Command Syntax

Manual Conventions

The manual uses these conventions when displaying command information. These ch aract ers are not par t of the command but are us ed to denote parameters used with the command.

< > (angle brackets) Angle brackets enclose a parameter. Do not include

/ (slash) Separates two alternative parameters. When a slash

separates two para meters, you can use either parame ter to achieve the s ame result. Example:

Entering

<1/ON>

1 or ON will achieve the same result.

3–2 TM-XR9B-01XN

Command Format and Parameters

The device-dependent language for the Ethernet/R S- 2 32 In terface consists of commands and parameter s. A command is a one word code which either gives instr uctions 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>,<pa rame ter>

• 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 paramet er. 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 FOLD

VOUT 3.4 = VOUT 3.4 VOUT 3.4 ≠ VOUT 3. 4

• 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 a ll owed and it may be preceded or followed by any number of spaces.

Example: MASK CV, OV, FOLD

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

T erminators 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.

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 registe r, the controller returns a response which is the sum of the weights of all relevant conditions.

Example:

ASTS? Query the Accumulated Status register. ASTS 771 Controller response. 771 = 512 + 256 + 2 + 1 = PON + REM + CC + CV

The accumulated sta tus register shows that PON, REM, CC and CV have all been active since the last accumu l ated statu s regist er q uery.

T able 3-8 shows the m nemoni cs and bi t we ights whi ch correspond to each

register condition. You can select conditions you want to monitor in the fault and status regis ter by using the MASK and UNMASK commands.

Introduction

Calibration

WARNING

You can calibrate the interface in either Ethernet or RS-232 mode by adjusting the signal le vels on the interface card so that they corres pond to the expected signal leve ls on the power supply's main assembly. Y ou 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 specificati on due to component aging drifts.

Calibration

You can calibrate the Ethernet/RS-232 Inte rface 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% accura cy 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 accor ding to the following procedures, referring to

“Command Reference” for more information about the calibration

commands used. The calibration procedures in this section ar e designed to be p erf ormed at

an ambient temperature of 25°C ± 5°C.
