RTX2-U2 LINK MODULE RTX2-U2 PROGRAMMING INTRODUCTION Using the RTX2-U2 PC programming cable and software gives access to all programmable functions and features. The RTX2-U2 programmer enables you to:
Input new settings, frequency data Customise RTX2-U2 radio to your own requirements Read the settings of an already existing RTX2-U2 and store these data as files. Clone channel and other important information from one radio to another Gain access to a range of other product features 2005.03.08. page-17-
RTX2-U2 LINK MODULE GETTING STARTED When you receive your RTX2-U2 PC programming kit, make sure the following items are included:
RTX2-U2 software (on 3.5" disk) Programming cable TO RUN THE RTX2-U2 SOFTWARE The programmer works on most IBM compatible PCs. However, the minimum software and hardware requirements you need to run RTX2-U2 successfully are:
DOS 3.0 or later 512K Bytes of memory One parallel port HARDWARE CONNECTION:
IMPORTANT! In order to access the programmer connentor, you need to take off the upper cover. To do so, unscrew the four upper mounting screws located on the upper cover of the radio. With the PC switched off, connect the programming cable /25-way D type connector/ to a vacant parallel communication port on the PC /typically on to the PC printer port /, and the 5-
poled end of the programming cable to the programming socket of the RTX2-U2 transceiver. For a smooth performance we suggest installing the RTX2-U2.exe directly onto the computer's hard disk. It will require approximately 400K of disk space. Running software from hard disk :
The programming of the equipment is to be done while it is switched off. / without external Power Supply /
Start running the RTX2-U2. exe . PROGRAMMING A RADIO The programming screen consist of the following:

RTX2-U2 LINK MODULE SETTINGS CHANNEL DATA You can set 16 transmitter-receiver frequency-pairs in the 440-470 MHz band. Selection of channels: with the up/down arrows. You can select TX power either High: 2W or Low: 0.5 W for each of the channels. 2005.03.08. page-19-
RTX2-U2 LINK MODULE PARAMETER RX/TX in
/ PTT /
A: the transmission starts on low level /0 V/
B: the transmission starts on high level /+5V/
Where:
Low level: <1V High level: >3.5V-15V SCAN :
FREE CHANNEL BUSY CHANNEL NONE Starting from channel 1 / or which has the lower channel number/
it will search for a free channel among the preset channels. preset channels: where both TX and RX frequency are set. Starting from channel 1/ or which has the lower channel number/ it will search for a busy channel among the preset channels. The receiver will use the channel data, which is set by the DIPswitch. BUSY CHANNEL LOCKOUT If selected, you can only start sending a message if there is no present busy signal in the given channel. 2005.03.08. page-20-
RTX2-U2 LINK MODULE RASTER 5 kHz 6.25 kHz The preset channels are located on a 5 kHz raster The preset channels are located on a 6.25 kHz raster TX TIME OUT DROP OUT Limits the amount of time that the user can continuously transmit
/can be set from 10 seconds to 990 second /
In SCAN FREE and SCAN BUSY CHANNEL mode the drop out time of the presence or absence of the busy detect signal can be set between 4-510 msec. /drop out time as result, the equipment will step on the next channel. /
PROGRAMMING PORT SETTING Here you can select which computer-port to connect the programming cable to. /LPT1.2, 3/

RTX2-U2 LINK MODULE LOAD WRITE READ This command programs the radio according to the above parameters. Note: On programming a radio, all the information previously contained in the RTX2-U2 will be lost. The preset values/data can be checked or read from the settings of an already existing RTX2-U2. /for cloning/
