Operation RF-Baton! Transmitter Controller Installation and Operation
5-14 6880497G01-B June 1999
Operation Modes
The RF-B! transmitter controller has three operation modes:
Normal paging mode
Trace mode
Test-data mode
Note: The trace mode, and test-data mode are test modes that can interfere with normal transmitter
operation. These modes are for advanced diagnostics only and may require assistance from a
Motorola service representative.
Normal Paging Mode
This is the normal and default mode of operation for the RF-B! transmitter controller. Upon
any type of reset, the RF-B! transmitter controller control software returns to paging mode
after GPS and Simulcast initialization. While operating in this mode, all RF-B! transmitter
controller functions are available, and input message data is transferred to the transmitter.
Paging with GPS
During normal paging operation, the RF-B! transmitter controller simulcast manager monitors
GPS lock. While operating with GPS lock, the station time is synchronized with GPS time.
Paging with FREERUN
The RF-B! transmitter controller can temporarily operate in FREERUN, a condition when the
simulcast manager has lost GPS lock. During this time, the RF-B! transmitter controller
simulcast manager maintains normal paging operation while attempting to reacquire GPS
lock. If GPS lock is reacquired within the FREERUN time-out value, the RF-B! transmitter
controller simulcast exits FREERUN and continues operation with GPS. If GPS lock is not
reacquired, paging operation is disabled until GPS lock is re-acquired.
Note: The FREERUN timeout value is programmable. The factory default is 96 minutes.
