1.2.4 Remote Maintenance Monitoring System
The integral Remote Maintenance Monitoring (RMM) system operates in conjunction with the Local Control Unit and
Portable Maintenance Data Terminal (PMDT). It consists of the various embedded sensors, internal monitoring points,
microcomputers and built-in test equipment to remotely monitor, control, record and certify proper operation of the
Marker Beacon subsystems.
In addition to local access to the RMM system through the built-in RS-232 port, and remote RMM access through a dial-
up telephone line and the Portable Maintenance Data Terminal (PMDT), the Remote Control and Status Unit (RCSU)
computer and modem may be utilized for dial-up access to the RMM system.
All components of the RMM subsystem meet the requirements for Class A computing devices in accordance with
subpart B, Part 15, and certification in accordance with subpart J, Part 2 of the FCC Rules and Regulations.
1.2.5 RMM Functions
The RMM system provides the following key functions:
a. System control.
b. Adjustment of transmitting parameters on the Marker Beacon system. For security, this feature is available only at
the respective station by default. Each station may be optionally configured to allow adjustment from a remote
location.
c. Monitoring of system performance and certification parameters. Compares the outputs of each of the monitoring
devices to determine alarm and alert status by comparing the monitored values to pre-determined limits.
d. Adjustment of all alarm and alert monitoring limits. For security, this feature is available only at the respective
Localizer or Glideslope station by default. Each station may be optionally configured to allow adjustment from a
remote location.
e. Monitor Certification.
f. Storage of monitor alert and alarm data.
g. System Fault Diagnostic routines with result storage and reporting for Localizer and Glideslope systems. On-Air
diagnostic routines for the Localizer and Glideslope stations may be initiated either locally at the station or remotely.
Diagnostic routines which require the respective station to be NOTAMED out of service must be run locally at the
station by default. Each station may be optionally configured to allow all diagnostic routines to be run from a remote
location.
h. Monitoring of routine maintenance parameters including voltages and currents and VSWR.
i. Monitoring of environmental parameters (when optional sensors are installed).
j. Monitoring of primary AC power applied to the system.
k. Monitoring of standby battery voltage and current.
l. Printing of menus and all display/parameter values.
