2 Parity Check

The parity check is used for error correction during data transmissions. If parity-
checking has to be disabled, the shunt on the Parity jumper switch should be
removed.

Parity ON (Default)

Parity OFF

Normally leave this
setting alone.

By factory default, the Parity switch is set to “ON” and should normally be left in
this state.

3 Termination

Terminators prevent SCSI signals from being reflected off the last device in the
chain. The SCSI terminator switch should be set to “ON” if the CRW8824S is the
last device on the internal SCSI chain. If the CRW8824S is not the last device on
the internal SCSI chain, the shunt on the Terminator jumper switch should be
removed.
