Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2

This command cancels a previously issued ASSIGN command and the SV channel reverts to automatic control (the same as ASSIGN AUTO).

Message ID: 29

Abbreviated ASCII Syntax:

UNASSIGN channel [state]

Input Example:

UNASSIGN 11

Issuing the UNASSIGN command to a channel that was not previously assigned by the ASSIGN command has no effect.

For dual antenna receivers:

  • On the primary antenna, the SV channel is from 0 to N-1, where N is the number of channels in the primary antenna channel configuration.

  • On the secondary antenna, the SV channel count is from at N to N+(M-1), where M is the number of channels in the secondary antenna SV channel configuration.

  • Even though L-Band channels cannot be configured with ASSIGN or UNASSIGN, they are included when determining N.

The ASSIGN and UNASSIGN commands are not accepted for L-Band channels. The ASSIGNLBANDBEAM command should be used for L-Band channels.
