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.

Installation and Configuration Changing Internal Jumpers Some of the settings on the 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. 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.
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 to locate the various components and jumpers on the PCB.
Installation and Configuration Basic Setup Procedure - This procedure can be used as a quick reference for those familiar with the configuration requirements for the installed in the DC power supply. For those who want more information, each step refers to more detailed procedures located in subsequent sections.

Installation and Configuration Configuring for Ethernet or RS-232 This interface card can be configured for RS-232 the instrument will be configured for 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.
Ethernet Communications Ethernet Connection There are two options for controlling your XFR power supply via Ethernet 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.
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: ______________________________ 2. Insert the Xantrex XFR Ethernet Software Utilities CD into your CD drive.
Configuring Ethernet Bridge Ethernet/RS-232 Interface 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.
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 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.
RS-232 Communications RS-232 Connection Use an approved RS-232 connector and null modem cable when connecting the connector uses the 9 pin mating connector on the rear panel. shows the pinouts for the RS-232 connector. Refer to on the rear panel subplate. Figure 2-5 RS-232 Connector Pinouts TM-XR9B-01XN WARNING...
Installation and Configuration Baud Rate Selection Serial transmission sends and receives data in bit streams at fixed bit rates. Both the computer and the interface must have the same bit rate setting for proper communication. The default baud rate is 9600. We recommend that you do not change this setting.
Flow Control Selection Flow control signals regulate data flow for proper communication. To enable or disable the flow control, change the J2 FLW jumper according Table hardware protocols to control flow rates. You will need to remove the cover to change any jumpers. See page 2–8.
Installation and Configuration Remote/Local Operation Remote/Local Mode Startup The power supply can be set to start-up in remote or local mode. To change this setting, the PON REM jumper must be adjusted according to Table 2-9. You will need to remove the cover to change any jumpers. See “Changing Internal Jumpers”...

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.
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.
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 Ethernet/RS-232 Interface information on how to use over voltage protection and TTL shutdown. OVP Selection Over voltage protection (OVP) on the the factory for remote software operation.
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 shutdown is activated by a TTL signal to Pin 1 of the user lines connector on the interface subplate.
Installation and Configuration User Signals User Lines Connector Auxiliary User Lines connector, located on the 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.
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.

Command Format and Parameters The device-dependent language for the 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.
