Install the ferrite cores within 50 mm of the camera-side connectors. (Fasten the ferrite
core with the wire clamp provided.)

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.

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:
TK-C1480BE Isolated power supply only
TK-C1481BEG (AC230V)
Power cable connect to the commercial
AC230V outlet
CAUTION:
When you use this camera, the socket-out-
let shall be installed near equipment so
as to disconnect easily.
