s Connection with the Extension Units q SCSI Connection The Digital Disk Recorder WJ-HD500A controls the extension units through the SCSI chain. 1. Connect the supplied SCSI cable between the EXT STORAGE port on the WJ-HD500A 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 WJHDE505 if a further extension unit is connected. Use WJ-HDE500 if the 3rd unit is located at the end of the SCSI chain. Up to 6 extension units can be added.
