Sensor slit
•Beware of damage
1. Insert the DVD-R drive from the rear of the JVC Library.
Ⅵ Pay attention not to damage the sensor slit.
Ⅵ Always insert the DVD-R Drive correctly.
Ⅵ Check that cables connected on the rear of the unit are not caught
or pinched when inserting the DVD-R Drive.
2. Insert the DVD-R Drive slowly until the screw installation hole located
on the side of the DVD-R Drive and the screw installation hole lo-
cated on the drive locking section are aligned.
3. Lock the DVD-R Drive in place by using the drive locking screw on
the door panel side of the drive.

INSTALLATION
5. How to Attach the SCSI Cable
SCSI cable
Ⅵ
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.
Blind plate
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.
SCSI-D
SCSI-C
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.
SCSI-B
SCSI-A
Ⅵ Remove the connector cap of the SCSI cable for installation.
Ⅵ 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”.)
Connector cap
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
Ⅵ 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.
Ⅵ 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.
Ⅵ 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.
Ⅵ Insert all connectors firmly.

Ⅵ 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.
Ⅵ 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.

INSTALLATION
7. How to Set the DIP and Slide Switches
ⅥAlways turn OFF the power of Library when you set the dip switch modes.
1. TERM This selects the use of the built-in terminator.
ⅥTerminate the SCSI bus at the position where it physically terminates.
ⅥWhen using the built-in terminator, set theTERM for the drive located at the physical end of the SCSI bus to ON,
and the TERM for the other drives to OFF.
ⅥWhen not using the built-in terminator, attach an external terminator to the OUT side of the SCSI connector.
ⅥWhen using an external terminator, set TERM of all the drives to OFF.
ⅥTo improve the stability of SCSI bus communications, it is recommended to use an active external terminator.

ⅥSet the SCSI ID No. between 0 - 7 using only a ID No. that is not being used by other SCSI devices.
ⅥNote that the default SCSI ID of the Library is 0 and the SCSI card is 7.
ⅥFor the details on default factory settings, please refer to the section “SCSI ID No. SETTING” of the instructions
for the JVC Library.
ⅥBe sure to set the slide switch to N for use. (The position W is provided for use in servicing.)
8. How to Reattach the Drive Storage Cover
Ⅵ Always reattach the drive storage cover before switching ON the JVC Library.
1. Fasten the panel with the screws that were removed in procedure (refer to “2. How to Open the Drive Storage Cover” on
page 4).
9. How to Close and Lock the Door of the JVC Library
Ⅵ Always close and lock the door before switching ON the JVC Library.
1. Close the door and lock the key cylinder.
10. Automatic Drive Detection Mode
Ⅵ Please also refer to the corresponding sections in the CD/DVD Library instructions.
Ⅵ If using the CD/DVD Library MC-8100U/8200U/8600U, be sure to execute the auto drive detection mode after in-
stalling, adding, exchanging or removing drives, to prevent any malfunction.
1. While holding the “8” key on the control panel, turn on the power of the Library.
2. When the LCD display shows “DRIVE DETECTION COMPLETED”, turn off the power of the Library.
3. Turn the Library on again.
Ⅵ The DRIVE DISPLAY of the CD/DVD Library displays this drive as a “DVD-RAM”.
Ⅵ Before you install, add, remove or replace drives, and/or change the SCSI ID No., turn OFF the power of the host
computer. Remember to turn it ON again after completing the necessary operations.

INSTALLATION
11. Example of a SCSI Cable Connection
Ⅵ 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

Press the clamp filter against the connector
and fasten it with a provided band.
Tighten until the dabs
are completely locked.
Pull the band tightly.
Cut off any
extra length.
Fit the clamp filter around the cable.

Ⅵ 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
Ⅵ Read the following before installing this drive in your Library for the first time.
Ⅵ 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.
Ⅵ For the ROM replacement method, consult your dealer or nearest JVC-authorized service agent.
