■ Connection with the Extension Units
● SCSI Connection
The Digital Disk Recorder WJ-HD500B controls
the extension units through the SCSI chain.
1. Connect the supplied SCSI cable between
the EXT STORAGE port on the WJ-HD500B
and the EXT IN port on the 1st extension
unit.
2. Connect the supplied SCSI cable between
the EXT OUT port on the 1st extension unit
and the EXT IN port on the 2nd extension
unit.
Repeat connections in the same manner for
all additional extension units.
3. The 3rd extension unit must be a WJ-
HDE505B if a further extension unit is con-
nected. Use WJ-HDE500B if the 3rd unit is
located at the end of the SCSI chain.
Up to 6 extension units can be added.
● Switch Setting
Data termination and SCSI number settings are required, as
shown below.
1. Set the MODE switch #2 on the rear of the WJ-HD500B
to ON when connecting with an extension unit.
2. Set the SCSI ID number for each unit by pressing the
[–] or [+] button on the rear of the Extension Unit.
0 to 5 are applicable to the extension units.
Note: SCSI ID 6 and 7 are reserved for WJ-HD500B
Disk Recorder.
3. Set the termination switches on the rear of the Extension
Units to ON or OFF.
ON: Is applied to the extension unit located at the end
of the SCSI chain.
OFF: Is used for units other than the end unit.
