11. Example of a SCSI Cable Connection
When interconnecting the JVC CD/DVD Library and the host computer with a SCSI cable, use a high-impedance,
shield cable with two clamp filters fitted near both connectors.

● An operational error may occur when the total length of the internal and external SCSI cables exceed 3 meters
(with SCSI-2, 10 Mbytes/sec. sync). When the SCSI bus is used as SCSI-2, 5 Mbytes/sec. async, the total length of
the cables can be extended to up to 6 meters.
● Regarding the length of the provided SCSI cable is approx. 1 m (3.3 feet).
● The length of the SCSI cable inside the JVC CD/DVD Library refer to "CONNECTING SCSI CABLES AND POWER
CORD" in the operation manual for the main unit.
● Be sure to lock the connectors of the external SCSI cable once they are connected.

INSTALLATION PROCEDURE

1
Fit the clamp filter around the cable.
Signal disturbance may occur if a high-impedance, shielded SCSI cable is not used. Also, the above clamp
filters are necessary for the JVC CD/DVD Library in order to comply with EMI Standard 'EN55022 Class A'.
