Parity Check

This function detects vertical parity in the data output on the data output lines (OD0 to OD15) and outputs the
parity status. If the number of bits that are ON in the data output lines is even, then the parity output is OFF. If
the number of bits that are ON in the data output lines is odd, then the parity output is ON. The parity check is
performed for output data on the cable communications between the host device and the ID Flag Sensor. The
parity check can be used to effectively perform simple checks for disconnected cables or wiring.
The parity check cannot be used in Trigger Mode 2 or Auto Mode 2. The ID Flag Sensor indicates a Setting Error.
