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

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 CRW8424S is
the last device on the internal SCSI chain. If the CRW8424S is not the last device
on the internal SCSI chain, the shunt on the Terminator jumper switch should
be removed.
n
By factory default, the Terminator switch is set to “ON.”
