Important ! Some functions are duplicated by
both, the JUMPER and DIP-Switches. One or the other should be used per function. DO NOT set both
locations to the same function. (i.e. If you set dip switch 1 to ON and install a jumper on pins 5-6, the drive
will be set to SCSI ID 5).
SCSI ID selection (Switch or Jumper)
| SCSI-ID | SW-3 | SW-2 | SW-1 |
|---|---|---|---|
| ------- | J5-6 | J3-4 | J1-2 |
| 0 | Off | Off | Off |
| 1 | Off | Off | ON |
| 2 | Off | ON | Off |
| 3 | Off | ON | ON |
| 4 | ON | Off | Off |
| 5 | ON | Off | ON |
| 6 | ON | ON | Off |
| 7 | ON | ON | ON |
DDS-Pass Through Mode - Hardware Compression settings
DDS-Pass Through Mode (hardware compression) is enabled or disabled by either SW-6 or jumpers 9-10.
The default is DDS pass through mode disabled (SW-6 = OFF, jumpers 9-10 = OFF).
If using the DIP switch to set DDS-Pass Trough mode, remove jumper from pin 9-10.
| SW-6 = ON | enable pass through |
|---|---|
| Data Compression disabled. | |
| SW-6 = OFF | disable pass through |
| Data Compression enabled. |
Media Recognition and Parity Checking
Media Recognition System (MRS) setting and Parity configuration must be set using the DIP-switches.
The SW-4 switch enables/disables the MRS-mode. The default is MRS disabled (SW-4 = ON).
If MRS is disabled (SW-4 = ON), the drive read/writes to MRS and non-MRS media.
If MRS is enabled (SW-4 = OFF), the drive will write to MRS media only.
The SW-5 enables/disables parity checking. Default parity is disabled (SW-5 = OFF).
