• “.” - A period indicates that the modulator or demodulator is reporting status normal.
• F - Indicates that the modulator or demodulator is reporting failure status.
• ? - Indicates that the status monitor for a channel on the DDS20 is either missing or
malfunctioning. If this symbol appears on one channel, check to see that the Data Switch Module
is inserted correctly for that channel. If this symbol appears on all the channels, verify the cable
connection between the DDS20 and the RCU20.
IMPORTANT
When a channel is configured for linked switching, either a modulator fault or a
demodulator fault will report both modulator and demodulator faults to the RCU20.
