TRANSCEIVER OPERATION (Continued)
1. Set-up Tab
This screen is used to set the PC Serial Port to interface with the MiniLink Data 900
or 2400 MHz Transceiver. The parameters in this tab must match the PC Serial Port
Parameters for communication to be established.
2. Com Test Tab
This screen is used to test the MiniLink Data transceiver and monitor
communications once the two transceivers are both set to match the parameters of
your system.
Running a Com Test: (See Notes and instructions on the CTU Software below before testing)
1. Two Data transceivers must be in RS-232 mode, powered up, and antennas attached in
order to communicate with one another.
2. One transceiver must be connected to a PC or laptop using the 9-pin DBP Serial Cable
to the PC’s Com Port A, with the CTU Software loaded and running. The other unit must
have pins 2 and 3 grounded with a paper clip.
3. Click on the “Com Test” tab & click “Start”. Test results should appear on the screen
(Either “Good” or “bad”). You can click “Stop” when you like. Click “Clear Results”
and switch the units to make sure they pass the test as a transmitter and as a receiver.
3. Configuration Tab
This screen is used to configure the MiniLink Data 900 or 2400 MHz Transceiver parameters.
• To establish communication between the MiniLink Data Transceiver and the
MiniLink-CTU Software, click on the configuration tab, and select “Show Advanced
Set-up” then click on the “Get Parameters Using Com Port A” tab. The AT
command mode, Sleep, Radio Set-up and Network field will populate if the Baud
Rate on the “Set-up” tab and the Baud Rate of the radio match. (Factory set to 4800).
If the fields do not populate, check the Com Port A setup parameters and retry.
• To change parameters, click on the field or drop down arrow you wish to change and
enter the desired value. Click “Program Module” to send the new parameters to the
MiniLink Data Transceiver. In most cases, only the Baud Rate will need to be
changed.
• To verify that the radio is now configured to the desired parameters, click on the
“Set-up” tab and set all applicable fields to the new setting and click on the
“Configuration” tab. Then click on “Get Parameters Using Com Port A” and all
fields should populate and represent your desired settings.
