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.
