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 f or 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 corre sponding jumpers.

Jumper positions for Ethernet or RS-232

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 setti ngs are also changed by adding or removing jumpers, so it is best to perfor m this adjustment, if necessar y, while the interface card is accessible. Refer to “Baud Rate Selec tion” on page 2–18,

“Flow Control Selection” on page 2–19 and “Remote/Local Mode Start up” on page 2–20 for more detailed information on how to

reconfigure these settings.

Note: If you are switching the inte rface 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 Connection

There are two options for controlling your XFR power supply via

Ethernet - "Connect ing to a Network" or "Connecting Dire ctly 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 con nect the XFR directly to your computer's networ k interface card (NIC). This bypa sses the need for an existing networ k.

Connecting to a Network

All that is requir ed to conn ect your XFR to a net work is a straig ht thr ough CAT 5 network cable and an available network port.

Connecting Directly to your Computer

Ethernet Communications

To connect your XFR dire ctly to your com puter 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 addr ess. Check with your IT department for assistance.

4. When the menu appears, click Xantrex Device Dis covery to in stal l and run the application. This application will find and list a ll 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 inst rument wi ll already ha ve an IP a ddress. If not, y ou will have to configure an IP address manually. Refer to steps 2 and 3 in “Configuri ng Ethernet Bridge” on page 2–15 for more information.

7. Write down the IP address so that you can acc ess the instrument via its web server, and for when you start communicating 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 packets to ser ial data signals for processing by t he embedded microcontroller. The Ethernet Bridge m ust 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 clic king on th e i nstrument ’s IP address. You will then need to enter the correct username and password to be able to configure the device.

Default Usernam e: 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 i nstrument. Again, you will be asked for the username and password. Once you have accessed the configuration page, follow these steps for proper setup.

Ethernet Communications

1. Click Configuration > Seri al Port, and ensure that the following

settings have been selected:

• Ba ud Rate: 9600

• Data Bits: 8

• Pa rity: None

• Stop Bits: 1

• Flow Control: None Click Apply onc e 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 automaticall y using DHCP and then click Apply. If your network doesn’t use a DHCP s erv e r, select Use the following IP addr ess: and enter an appropriate IP address, Subnet Mask and Default Gateway. .

3. Ask for assistance from your IT department to obtain a n appropriate

IP address, Subnet Mask, Default Gateway, Name Server, and Domain. Once you have made the a ppropria te ch anges, clic k Apply. If this changed the setting, the device will reboot, so you will have to renew your c onnection to its configuration webpage for any further configuration changes.

Installation and Configuration

Installing and Using RealPort®

Background

RealPort® software al lows you to keep using your existing appli cations that rely on COM ports and RS-232 links for communication purposes, instead of ha vi ng to de velop TCP/IP based network appl ications. Inst al led on a network-enabled PC, RealPor t® cre ates a virtual COM port. As such, your applic ation stil l thinks it is wor king with a real s erial por t, suc h 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 exi sting application.

Installation

RealPort® can be installed on any P C 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 automatica lly, double-clic k the My Computer icon, double-cl ick the CD icon and then double-click

autorun_main.htm.

3. When the menu appears, click Digi RealPort®.

4. Follow the on-scr een instructions for proper installation.

Note: RealPort® driver s for UNIX systems are availa ble. Contact your

Xantrex repre sentative 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 applicati on (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.

Additional User Options and Settings

You can customiz e remote operation settings for OVP (over voltage protection) control and TTL shutdown by changing jumper posit ions on the Ethernet /RS-232 Interface card. Ref er 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/R S-232 In terface 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 com mand or the front pane l LOCAL switch, control of the OVP trip level changes from sof tware control to the front panel OVP potentiometer . The default OVP trip level is set as 110% of the power supply's rat ed output voltage. See Table 2-10 on page 2–21 for a complete list of remote power ON defaul t 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 changi ng the jumper se ttings, you can i solate the location of OVP c ontrol to so ftware co ntrol on ly or f ront panel control 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 enabl e the supply's output. Disa bling 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 a ctivated 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 c onnect or , loc ated on th e Ethernet/R S-232 Inter face rear panel, provide s 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 pr ovide external Vcc and ground. Use a standa rd 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 Ta ble 2-14 for pin descript ions. 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.

Introduction

Operation

This section covers Ethern et/R S- 2 3 2 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 powe r supply and computer, relying on bit serial communication. You can use the computer cont roller 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 confi gu re d 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 use s these conventions when displaying command information. These charact ers are not pa rt of the command but are used to denote parameters used with the command.

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

/ (slash) Separates two alternative parameters. W hen a slash

the angle brackets in the command li ne you send to the computer.

separates two para me ters, you can use either parameter to achieve the same result. Example:

Entering

<1/ON>

1 or ON will achieve the sam e result.

3–2 TM-XR9B-01XN

Command Format and Parameters

The device-dependent language for the Ethernet/RS-232 Interfa ce 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 c ode that changes the stat e 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

Command Syntax

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 mne monic parameters as in the MASK and UNMASK commands. Only one comma is all owed and i t may be preceded or followed by any number of spaces.

Example: M A SK C V, OV, FOL D

Command Strings

If you send more than one command line, separate the commands with a semicolon. The semicolon may be prece ded 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 ter mination character is CR (Carriage Return).

Format:

COMMAND <parameter >; COMMAND <parameter>, <parameter><CR>

Command Syntax

Order

You may send commands in any order, keeping in mind that only those commands received after a HOLD and before a TRG (trigge r) 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.

Operation

Table 3-7

Command Descrip tion

Command Reference

DLY <seconds> Sets a programmable ti me delay employed by the su pply before reporting fault

conditions. The power supply uses the time delay after receiving a new output voltage or curre nt 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 pos sible nuisance foldback if the supply momenta rily switches modes while changing an out put setting. Range: 0 to 32 seconds, with 32ms resolution Initial value: 0.5 second

DLY? Asks for the setting of the programmable time delay before the suppl y reports fault

conditions. Response: DLY <seconds>

ERR? Asks for the most recent remote programming error. When the power supply

detects a program ming error, it lights the ERR LED and sets the ERR bit in the accumulated sta tus and fault registers . If the error bit has been masked using the MASK command, then the ERR bit in th e r egisters will not set. Once an error is detected, the re maining 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 sta te of the fault register. A bit is set in the faul t r egister when a fault

arises for that condition. Lists the conditions whi ch 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 faul t register it also assert s a si gnal 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 co nditions as listed in the fault regist er. See

“Accumulated Status, Status, and Fault Registers” on page 3–17.

FOLD <2/CC>, < 1/CV> , <0/OFF>

Sets foldback mode for the supply. Foldback protection disables the power supply output when the output enters the fold condition. Reset with the RST command. Example: Specify FOLD 1 or FOLD CV (Constant V oltage) when you want the supply to operate in Cons tant Current mode and have foldback protection disable the output if the supply sw itches to Constant Voltage mode. Initial value: FOLD 0/OFF

See als o“Remote/Local Operation” on page 2–20.

HOLD <1/ON>, <0/OFF>

Enables or disables voltage/current setting hold mode for the supply. When HOLD ON is specified, hold mode is enabled so tha t all voltage and current settings which would normally be implemented by the supply are held until a TRG (trigger) command is rec eived. This feature allows you to synchr onize the operation of severa l supplies. Initial value: HOLD OFF or HOLD 0

HOLD? Asks for the present hold mode setting.

Response: HOLD 0 (OFF or disabled) or HOLD 1 (ON or enabled)

ID? Asks for the power supply model and the mast er EPROM version.

Response: ID <model name >< vers ion>

IDATA <Ilo>,<Ihi>

Calculates and rec ords the slope and offset for programmed current using ILO and IHI data. Set CMODE ON before using this command. See also the calibratio n procedures in Cha pter 4. <Ilo> and <Ihi> are in <current> format .

IHI In response to this command, the power supply s ends a programmed current value

to the output terminal. This value is at the high end of the power supp ly’s current range and is read b y 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 Cha pter 4.

ILO In response to this command, the power supply sends a programmed current value

to the output termi nal. This value is at the low end of the power supply’s current range and is read b y an external device connected as part of the calibration procedure. Refer to this value as I LO and record it to use as input with th e IDATA command. Set CMODE ON before using this command. See also the calibration procedures in Cha pter 4 .

Command Descrip tion

Command Reference

VRHI The power supply outp uts a voltage value to an external voltmeter connected as

part of the calibration procedure and records a voltage readback value internally. These values are at the high end of the programmed voltage range. Refer to the output val ue a s VRHI and record it to use a s input with the VRDAT command. Set CMODE ON before using this command. See also the calibration procedures in

Chapter 4.

VRLO The power supply outp uts a voltage value to an external vol tmeter connected as

part of the calibration procedure and records a voltage readback value internally. These values are at the low end of the programmed voltage range. Ref er to the output value as VRLO and reco rd it to use as i nput with t he VRDAT command. Set CMODE ON before using this command. See also the calibration procedures in

Chapter 4.

VSET <voltage> or VSET <-voltage>

Sets the power suppl y’s output voltage in volts (default) or in millivolts. This programmed voltage is the actual output in CV (constant voltage) mode or the voltage limit in CC (constant current) mode. If you enter a negative volta ge value, the power supply wil l assert a signal on Pin 4 of the us er signal line. You can use the user signal to trip external relays to switch the output polarity. Range: 0 to m o d e l m ax i mum ou t put vo l tage (VMAX) Initial value: 0 volts

VSET? Asks for the power supply’s present output voltage setting. Does not apply to

voltage settings which are being held. See HOLD command. Response: VSE T <voltage>

Accumulated Status, Status, and Fault Registers

The Ethernet/RS-232 Interface card uses three separate registe rs 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 regist ers. The bit register has

twelve conditions, each assigned a bit weight. When quer ying a regi ster, 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 Controll er response. 771 = 512 + 256 + 2 + 1 = PON + REM + CC + CV

The accumulated status register shows that PON, REM, CC and CV have all been active sin ce the la st acc um ul at ed stat us reg ister q u ery.

T able 3-8 shows the mnemoni cs an d bit we ight s which corre spond to eac h

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

Introduction

Calibration

WARNING

You can calibrate the interfa ce in eit her 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 suppl y board, or if the unit falls out of specification due to component aging drifts.

Calibration

You can calibrate the Ethernet/R S-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 calibra tion

commands used. The calibration procedures in this secti on are designed to be performed at

an ambient temperature of 25°C ± 5°C.

Over Voltage Protection (OVP) Calibration

We recommend that you perform OVP calibration eve ry six months. Connecting a digital voltmeter as in “Voltage Calibration Setup” is optional.

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 minute s.

5. Use the OVSET, OVSET?, and VSET commands to trip the OVP

level, confirming that the calibra tion 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.
