Terminal Mode Commands MN/KST2000L.IOM
7.3 System Configuration Commands
The commands and responses for setting the basic system parameters of uplink and
downlink frequency and attenuation, for making an adjustment on the internal reference,
and for disabling the RF output. Commands are included for setting and selecting
programmed frequency and attenuation values, for locking out changes in settings, and
for reading the status of settings.

Status
Response >add/UCF_nnnnn.n'cr''lf']

steps)
Up Converter

Command
Response
Status
Response >add/UCA_nn.n'cr''lf']
>add/UCA_nn.n'cr''lf'] Where nn.n = 0.0 to 20.0 (in dB, variable in 1.0 dB steps)
Note: No decimal point when AGC is Off.
Down Converter
Attenuation Command
Response
Status
Response >add/DCA_nn.n'cr''lf']
>add/DCA_nn.n'cr''lf'] Where nn.n = 0.0 to 20.0 (in dB, variable in 1.0 dB steps)

Command
Response
Status
Response >add/RFJ_nnn'cr''lf']
>add/RFJ_nnn'cr''lf'] Where nnn = 0 to 255 (full range is ~5000 Hz, nominal frequency
is ~10 MHz)
RF Output Command
Response
Status
Response >add/RF_xxx'cr''lf']
>add/RF_xxx'cr''lf'] Where xxx = ON, WRM, OFF, default = OFF
The OFF command will keep the RF output turned off under all
conditions. The WRM command is a conditional ON command
telling the RF output to come on after the unit is warmed up and
meets the stability requirements. The ON command is an override
instructing the output to be on and ignores the warm start.
