Cause and Effect
Cause—This message is output by the MCU
when it loses communication with the station.
This may occur if there is a fault in the page
line, if the station is powered-down, or if there
is some fatal malfunction within the station.
Effect—The MCU continues to attempt
communication with the station. When
communication is resumed, a restore message is
sent to the MCU.
Cause—This message is the same as the
"Polled device" fault, except that the affected
station has been defined as an end-of-line
station in the MCU configuration.
Effect—When this fault occurs, the red EOL
FLT LED on the PPI bezel lights. When
communication is resumed, the LED
extinguishes and a restore message is sent to the
MCU.
