5.How to Attach the SCSI Cable

If required two SCSI bus channels may be used by adding the provided SCSI cable. If the DVD-R is recorded intermittently due to an insufficiency in the recording transfer rate on the SCSI bus, the recording quality may deteriorate and playback malfunc- tions may occur.

1.While holding the two blind plates, remove the four screws on the SCSI connector installa- tion section at the rear of the JVC CD/DVD Library in order to remove the two blind plates.

2.Insert the provided SCSI cable through the installation hole from the back side of the rear panel and secure it with the four screws.

Remove the connector cap of the SCSI cable for installation.

Be sure that the SCSI connector is inserted in the correct direction. (It should be the same as the direction of the SCSI connector “SCSI-A”.)

3.If you are not connecting the SCSI cable to the OUT side of the SCSI connector “SCSI-D”, place the connector cap over it.

6.How to Connect Cables to the DVD-R Drive

Also refer to the corresponding sections in your Library Instructions Manual.

1. Connect the power supply cable, control cable and SCSI cable to the connectors at the rear of the DVD-R Drive.

When using the MC-8100U, the No. of the cable must always correspond to the No. of the drive bay to which it is being connected. If the cable with the wrong number is connedted, it will lead to the equipment malfunctioning.

When using the MC-8200U/8600U, connect power supply and control cables, which lead from the side of the DVD-R

drive bay to the drive.3

Insert all connectors firmly.

SCSI cable

Internal SCSI cable (additional)

•Up to two DVD-R drives can be connected

SCSI connector

SCSI-D(F)	OUT 2		Connect an active terminator.
SCSI-C(E)	IN	2	To be connected with host computer's SCSI host adapter No.2
SCSI-B	OUT 1		Connect an active terminator.
SCSI-A
	IN	1	To be connected with host computer's SCSI host adapter No.1

Internal SCSI cable (Standard)

•Up to 6 drives can be connected

(• Up to 4 drives in the case of MC-8100U)

SCSI cables should be connected as a daisy chain connection. Each connector may be connected to the drive posi- tions as illustrated in the diagram.

Terminate the physical end of the SCSI bus. For information on how to set the built-in terminator, refer to the item 1 “TERM” of “7. How to Set the DIP and Slide Switches”.

For an external terminator we recommend that an active SCSI terminator is used with the JVC CD/DVD Library.
