the decoder. This probably indicates the transmitter is not set
correctly.

Indicates the RX interface module has failed to program a current
configuration parameter. If this fault occurs, contact
EFData Customer Support for assistance.
CONFIGURATION Receive interface configuration fault.
Indicates the RX interface module does not support a
programmed configuration parameter. This fault typically occurs
when the programmed configuration does not match the module
hardware. Ensure the programming of the RX interface hardware
matches the configuration parameters. Also, verify all jumpers
have been set correctly for currently programmed configuration
parameters.
