➁Parity 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.

Note

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

➂Termination

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 CRW2200S is the last device on the internal SCSI chain. If the CRW2200S is not the last device on the internal SCSI chain, the shunt on the Terminator jumper switch should be removed.
