About This Manual

Purpose

This Operating Manual is for the XFR 1.2kW and 2.8kW Ethernet/RS-

232 Interface Option; a microproces sor-controlled option card for all

models of XFR Seri es DC output power supplies. This manual provides
you with specifications, user options, and configuration instructions for
the interface, along with a command set whic h allows you to control
your power supply from a computer console. Error messages and
calibration proc edures are also included.

Scope

This Operating Manual covers the inter face only. Refer to your power
supply manual for install ation, configuratio n, an d operating procedures
for your power supply.

Audience

This manual is de signed for t he user who is fami liar with bas ic el ectrica l
theory especiall y as it applie s to the operation of power supplies. This
implies a recognition of C onstant Voltage and Constant Current
operation modes and the control of input and output power, as well as
the observance of safe techniques while effecting supply or pin
connections and any changes in switch settings. The user should also
have experience with networ k-based communications software and
protocols.

Important Safety Instructions

WARNING: High Energy and High Voltage

Exercise caution when using a nd calibrating a power supply.
High energy le vels can be stor ed at the output volta ge te rminals
on a power supply in normal operation. In addition, potential ly
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. Filter capacitors sto re potentially dangerous energy
for some time aft er po w er is rem ov ed .

CAUTION

Operate the power supply in an environment free of flammable
gases or fumes. To ensure that the power supply’ s safe ty
features are not compromised, use the power supply as specified
in this manual and do not substitute parts or make any
unauthorized modifications. Conta ct the service technician for
service and repair help. Repairs must be made by experienced
service technicians only.

Description

Features

The Ethernet/RS-232 Interface is a microprocessor-controlled
option card for all models of the XFR series of DC output power
supply. Installed internally, the interface card allows you to
remotely control your power supply through your existing
network, or via a direct connection to your computer. It features
an auto-sensing 10/100Base-T network interface that provides fast
programming and readback utilizing an extensive command set.
You are able to select between Ethernet (factory default) or RS-

232 control by adjusting internal jumpers on the interface card.

Introduction

Configuration

The Ethernet/RS-232 Interface is usually installed at the factor y. Your
local distributor or service center can also install the interface,
especially for use in a previously-purchased supply already on site. You
must then configure the Inter f ace-enhanced supply for your system
using the “Basic Setup Procedur e - Ethernet” on page 2–10, or the

“Basic Setup Procedure - RS-232” on page 2–11.

To use this product, you must have the following equipment:

• a Xantrex XFR DC output power supply

• computer-based communications software package

Installation and Configuration

Also, depending on your specific configuration, you will need additional
items.

For Ethernet (via network):

• CAT 5 network cable to connect XFR to your network

• computer connected to the network

For Ethernet (direct to computer):

• CAT 5 crossover cable to connect XFR directly to your computer

• computer with network interface card (NIC)

For RS-232:

• null modem serial cable (cross over)

• computer with an RS-232 interface (serial/COM port)

Initial Inspection

On first receiving your unit, perform a quick physical check.

• Ensure each package contains a power supply with its Ethernet/RS-

232 Interface board installed, and manuals for the power supply and

the Ethernet/RS-232 Interface. Any additional parts shipped with the
power supply will be identifie d in the supply's documentation.

• Inspect the unit for any signs of physical damage such as scratches,

cracks, or broken switches, connectors, or displays.

• Check the printed circuit boa rd and components if you suspect

internal damage.

If the unit is damaged, save all packing materials and notify the carrier
immediately. For additional information, plea se see the section titles,
“Returning Power Supplies to the Manufacturer” in the manual shipped
with your complete unit.

Initial Inspection

CAUTION

If you remove the unit's cover, use proper static control
techniques to avoid damage to static-sensitive components on
the printed circuit board.

CAUTION

Use proper static control techniques to avoid damage to static­sensitive components on the printed circuit board.

Installation and Configuration

Changing Internal Jumpers

Some of the settings on the Ethernet/RS-232 Interface card are user
selectable by way of jumpers on the print ed circuit board. The procedure
for changing the jumpers varies depending on if you have a 1.2kW XF R,
or a 2.8kW XFR.

CAUTION

If you remove the unit's cover, use proper static control
techniques to avoid damage to static-sensitive components on
the printed circuit board.

Procedure for 1.2kW XFR

Ensure that the input power connection has been disconnected and the
unit is powe red off before you attempt to remove the top cover. Remove
all the screws holding down the top cover and then remove the cover. The
printed circuit boa rd that you need access to is upside down (component
side down), so you must remove all the screws that a re holding it in place .
Refer to Figure 2-4 to see which screws should not be removed.
