DATRAN XL4 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.
RTU Address
Every RTU has a unique site address so that a DATRAN base station can communicate
with it. When an RTU is installed at site, its address must be configured. Unlike older
model DATRAN RTUs, the address for the XL4 is configured using QTech Workbench.
The module address can be any number between 1 and 239.
Factory Defaults
From time to time it may be necessary for you 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.
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.

Supply Voltage: 12 Volts or 24 Volts
The DATRAN XL4 RTU can be supplied from 12-30V DC. The RTU comes factory
configured for a nominal 12V DC supply, unless otherwise requested. When configured
for 12V, the RTU will automatically shut itself down when the supply voltage drops to
10.5V.
