Notes:
29. C1.7 = Transmit Negative K28.5 (–K28.5+) disregarding Current RD.
The receiver will only output this Special Character if K28.5 is received with the wrong running disparity. The receiver will output C1.7 if −K28.5 is received with
RD+, otherwise K28.5 is decoded as C5.0 or C2.7.
30. C2.7 = Transmit Positive K28.5 (+K28.5–) disregarding Current RD.
The receiver will only output this Special Character if K28.5 is received with the wrong running disparity. The receiver will output C2.7 if +K28.5 is received with
RD−, otherwise K28.5 is decoded as C5.0 or C1.7.
31. C4.7 = Transmit a deliberate code rule violation to indicate a Running Disparity violation.
The receiver will only output this Special Character if the Transmission Character being decoded is found in the tables, but Running Disparity does not match.
This might indicate that an error occurred in a prior byte.
