Product Manual
NOTE: Use the commands in the same way you invoke the status screen; type “:” then the
appropriate letter for the desired command followed by a carriage return.
Command functions (front port only):
:? Show Status
To get current module status, type “:”; then “?”; then press enter.
This command will display the current status of the module
:V Show Version
To get module version info, type “:”; then capital “V”; then press enter.
This command will display the Module part number, firmware revision, build date, and other
version information.
:L Test LEDs
To check LED status and run lamp test, type “:”;L then press enter.
This command invokes a lamp test routine.
:a Show Attenuation
To check current attenuator value, type “:”; small “a”, then press enter.
This command displays the current attenuator setting.
:A<atten> Set Attenuation
To set the attenuator, type “:”; capital “A” then 3-digit attenuator setting 0-255 then press enter.
This command allows adjustment of the output level. The valid setting range is 0-255, 0 having
the maximum RF level and 255 having the lowest. The typical value will be around 190 to
achieve the proper nominal level. The RF output can be adjusted to work with a +17dBm mixer
as well as today’s 12dBm output level.
:X Set OCXO
To set the free-running OCXO frequency, type “:”; capital “X” then the setting.
This command allows adjustment of the free running OCXO. Meaning if the external reference
is not present and the module is equipped with the internal oscillator the tuning port voltage can
be adjusted to compensate the frequency of the internal oscillator. This acts as the hardware
potentiometer adjustment used in OEM models. The typical value will be between 690 and 850
to achieve the proper RF frequency.
