RUCTION

MANUAL

Connect the DC 12 V or the AC 24 V power

supply to the DC 12V/AC 24V terminals. To

prevent connection errors or a cable

disconnection, we recommend the use of lug

plates for the connections.

The following table shows the connection

distances and connection cables provided

that 2-conductor VVF cables (vinyl-insulated

vinyl sheath cables) are used.

Installing the ferrite core

To retain electromagnetic compatibility, use the ferrite cores provided when connecting to

the lens.

Notes:

• Install the ferrite cores within 50 mm of the camera-side connectors. (Fasten the ferrite

core with the wire clamp provided.)

• If the LENS cable is short, please connect the cable to the camera without winding the

cable around the ferrite core.

 Control signal cables

These cables should be connected only when

it is required to control the camera using the

RS-442A or RS-485 signals. The use of 0.65

4-conductor twisted pair cables is recom-

mended. With these cables, the maximum ex-

tension distance is 1,200 m.

Connect to the other

side in pairs like this.

 Genlock connection

With some systems, when the external sync

signal is a composite video or black burst sig-

nal genlocking by applying an external sync

input requires the horizontal phase (H

PHASE) and colour phase (SC COARSE) to

be adjusted.

MEMO

• Genlocking is not possible with a signal con-

taining too much jitter, such as a VCR or

videodisc playback signal.

•For details, consult a JVC authorized dealer.

MEMO

• If thin cables are used (i.e. with a high resistance), a significant voltage drop will occur when

the unit is at its maximum power consumption. Either use a thick cable to restrict the voltage

drop at the camera side to below 10%, or place the power supply near to the camera. If

voltage drop occurs during operation, the performance will be unstable.

• Attach the cable conductors so that they do not come into contact with the drop prevention

wires.

• Do not allow input from both a DC 12 V and AC 24 V power supply at the same time.

• When using a DC 12 V power supply, ensure that the polarities of the cable are correct.

• The AC 24 V power supply should conform to the following: Isolated power supply only

Power cable connect to the commercial

AC220V – 240V outlet

CAUTION:

When you use this camera, the socket-out-

let shall be installed near equipment so

as to disconnect easily.
