Quick Start Guide

DATRAN XL4 DNP3 RTU – Quick Start Guide – v1 – May 2012

Configuring the XL4

The XL4 is configured using software called “QTech Workbench”. Connection to your PC
is via a USB cable (Type A to Type B). The configuration software is available for
download from the QTech Website.

Factory Defaults

From time to time it may be necessary to reset the XL4 back to factory defaults. There are
two ways of doing this.

1) There is a jumper on the XL4 main processor board labelled “INIT”. It is normally
open, but if the RTU is started up while the jumper is installed it will cause the RTU
to restore the factory default settings.

2) The factory default settings can also be loaded back into the RTU using the ‘Factory
Default’ button at the bottom of the QTech Workbench screen when the Overview
branch is selected.

Status LEDs

ON: This LED is always on when the XL4 RTU is powered.
OK : This LED flashes on a 1 second cycle to show the CPU has not locked up.

If it is on solidly or stays off, then the XL4 RTU needs attention.

IP : This LED indicates that the XL4 RTU is currently sending comms out its

IPB port to communicate with I/O expansion modules.

MU : The MUTE signal from the Radio. This indicates the radio is currently

receiving an RF signal.

RX : The RTU modem is receiving and decoding data from the radio. This LED

will usually appear to “flicker”
KY : This indicates the RTU is attempting to key on the radio transmitter.
TX : The RTU is transmitting data through the radio. This LED will usually

appear to “flicker”
ER : This is the Error Indication LED. The LED will flash a certain number of

times to indicate any error messages the XL4 RTU has been configured to

display.
