RF-Baton! Transmitter Controller without GPS Receiver (Option X594)
The RF-B! transmitter controller, integrated with the transmitter, decodes the signals sent from
the RF-C! controller. The RF-B! transmitter controller is a 19-inch, rack-mounted module that
is two EIA rack units high (3.5 in.). Besides decoding the incoming information sent from the
RF-C! controller, the RF-B! transmitter controller performs secondary voice processing for
InFLEXion protocol, accepts remote software downloads, and transfers software downloads
to the OCM.
A laptop computer interfacing with the RS-232 FIPS port on the RF-B! transmitter controller
can be used to program transmitter parameters and run diagnostic traces. The RF-B!
transmitter controller must be connected to an external GPS receiver for time synchronization.
The software is set up to handle the Trimble Accutime II GPS Receiver.
RF-B! Transmitter Controller with GPS Receiver (Option X179)
This option is the same as Option X594, but includes the Motorola GPS receiver. The GPS
receiver detects the signals from the U.S. Department of Defense NAV STAR GPS satellites.
The GPS receiver is used for time synchronization and optimal simulcast performance.
Battery Revert (Option X649)
The battery revert option includes the batteries, cables, and tray. This option provides power
to operate the RF-Baton! transmitter controller and network modems in the event of a power
failure for up to 6 hours.
RF-O! Transmitter Peripheral Options (Option X263)
Several transmit filtering options are available to minimize interference with communications
equipment located within transmission range. Included in this package is an integrated
external wattmeter with a feedback loop to the exciter for additional power control
capabilities. Filtering requirements are determined by site and customer system requirements.
