INSTALLATION

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.

Attach the active terminator to the OUT connector.

ENGLISH

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

Tighten until the dabs

are completely locked.

 

Pull the band tightly. Cut off any extra length.

1Fit 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’.

PRECAUTIONS BEFORE USE

Read the following before installing this drive in your Library for the first time.

To mount this drive on the MC-8100U/8200U/8600U in your Library, the firmware of the CD/DVD Library should be upgraded. Please change the ROM in the CD/DVD Library to the ROM provided with this drive.
