CONNECTION/INSTALLATION

Installing the ferrite core

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

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

Wire clamp

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.

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.

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.

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.
