Section 9: Control and monitoring
This section describes control and monitoring of the XR12 transmitter. This section includes the
following topics:
• Controls
• Alarm definitions
• Remote control circuits and alarms - see page 9-6
• Remote performance monitoring - see page 9-11

Controls
The XR12’s graphic user interface (GUI) lets you control a number of transmitter functions and set
parameters and schedules. (For detailed information about the GUI, refer to the
XR12 Operating and
Maintenance Manual .) In addition, you can control the on/off status, the active (A/B) exciter, the preset
RF power level, the power level adjustment, and system alarm reset remotely by means of a
conventional remote control interface (see
“Remote control circuits and alarms” on page 9-6 or a
LAN, using the optional NxLink module (see “LAN interface (NxLink)” on page 9-12 ).
