3.2 Initial Installation—Radio and Data
Configuration
Below are the basic steps for setting up of the transceiver once it is
installed in the user’s product. In many cases, these steps alone are
sufficient to complete the installation. This procedure assumes the
TRM SB has been installed in your system/product and suitable
connections have been provided for a terminal interface and antenna.
3. Install the antenna and antenna feedline for the station. Preset
directional antennas in the desired direction of transmission and
reception.
4. Connect a terminal (computer with emulations software) to the
TRM SB through the user’s product interface. (async @ 38400
w/8N1)
5. Enable the configuration mode for the TRM SB radio. (Ground
Pin 11 of the radio transceiver’s

will appear on the terminal screen terminal once diagnostics
communication with the radio is established.
6. Review the existing essential TRM SB configuration parameters
through a series of terminal commands.

MODEM—Data Configuration
Response indicates:
Payload data rate (
BAUD)
Gaussian Bandwidth x Data Rate (
BT)
Channel Spacing (
BW)
For example:
9.6Kbps BT=.5 25KHz.
•
PWR—RF Power Output
Responses: H = 2 Watts, L = 0.5 Watts
7. Check and set the radio transmit and receive frequencies.
NOTE: The operating frequencies are typically not set at the factory.
Determine the transmit and receive frequencies to be used, and
follow the steps below to program them. The TRM SB must be
programmed for the frequencies for which you hold a valid
license and be within the radio’s operating band.
a. Set the transmit frequency with the
TX xxx.xxxxx command.
Press after the command.
