LPOD-R Outdoor Amplifier / Block Up Converter (BUC) MN-LPODR
Introduction Revision 3

1.4.6 Monitor and Control (M&C)
The LPOD-R includes a microprocessor-based system that provides monitoring
and control of the essential parameters of the unit. You interface with the unit
through the M&C system via the remote control/discrete communications port.
The unit is capable of Ethernet remote communication, while EIA-232/485 is
optional on the PS 1 and PS 1.5 packages. A discrete mute control and relay
status output is also available on the PS 1 and PS 1.5 packages.
The M&C system monitors the fan speed, unit temperature, all power supply
voltages, power transistor currents, output power, etc. Should a critical
monitored parameter fail, the unit will mute the RF signal and report a fault. The
details of the fault can be accessed via remote communication.
The LPOD-R PS .5 features a Light-Emitting Diode (LED) Indicator. Figure 1-3
shows the location of this feature, on the signal output side of the LPOD-R PS .5
housing, next to the ground lug. This LED provides you with visual cues to the
operational, online, and offline status of the system. See Chapter 2 for complete
details about interpreting LED operation.
