7.5 Detailed Command Descriptions and System Responses
This section defines each of the command codes and the associated parameters.
FL - Load Frequency
Description: Loads the frequency for the specified module.
Parameters: Desired frequency in MHz, in the form XXX.XXXX. Leading zeros are optional, but not required. The
decimal point and four trailing characters are required. Valid input frequencies are between 53.0000 MHz and
857.0000 MHz. Valid trailing characters are multiples of 0.0125 MHz, all others will be denied.
857.0000 MHz. Valid trailing characters are multiples of 0.0125 MHz, all others will be denied.
Example:
*999<sp>A<sp>FL<sp>800.0625<sp>CRC<cr>
Response: OK or MOD or ERR or CRC
AI - Set IF Attenuation
Description: Sets the IF attenuation for the specified module.
Parameters: Desired IF attenuation in dB, in the form XX.XX. Leading zeros are optional, but not required. The
decimal point and two trailing characters are required. Valid attenuation values are between 0 dB and 31.75 dB in
0.25 dB steps. Valid trailing characters are 00, 25, 50 or 75.

Response: OK or MOD or ERR or CRC
ITS - Set IF Threshold
Description: Sets the IF thresholds for the specified module.
Parameters: Desired IF thresholds in dB, in the form X.X<sp>-X.X. Leading zeros are optional, but not required. The
decimal point and trailing character is required. The first parameter is the positive threshold and can range between
4.0 and 0.0 dB. The second parameter is the negative threshold and can range between 0.0 and -4.0 dB. The
trailing character can range between 0.0 and 0.9.
4.0 and 0.0 dB. The second parameter is the negative threshold and can range between 0.0 and -4.0 dB. The
trailing character can range between 0.0 and 0.9.
