This command gets the Orion Reader system line loss value. Table 6-163 and Table 6-
164 list the command and response data.
Set Uplink Source Control
The protocol-dependent Set Uplink Source Control command is used if the RF uplink
needs to use the RF downlink frequency, that is, Title 21 while running step-lock.
There are four uplink frequencies available. If more than four frequencies are needed,
then the Uplink Source Control command must be used to provide the remaining
needed frequencies with downlink frequency capability. Table 6-165 and Table 6-166
list the command and response data.
