Set/Request receiver unlock time-out delay
-
This command provides a user settable time out that will mask an unlock (holdover) condition from causing a
GPS REF module failure until the time out elapses. The time out is set in hours and days and if the STI is
requested while the GPS REF module is locked, the response will contain the user setting. However, if the GPS
REF module is in holdover, the STI responds with the user set timeout and the current minutes, hours and days
left for the timeout to elapse. If the timeout elapses, the GPS REF module will indicate a failure.
