M204.0508 Invalid control unit selection character: x'hexValue'
This message is issued during initialization (IODEV processing) when the high-order half of the DVADD parameter does not specify the hexadecimal equivalent of a valid control unit selection address. Model 204 continues, but addressing errors will occur and the control unit will eventually be dropped from polling. The hexadecimal appendage contains the invalid control unit selection address.
System manager response: Correct the DVADD parameter in the CCAIN parameters, and rerun Model 204.
Operator response: Notify the system manager.
