JVC TK-C1480B Manuel D'instructions page 17

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)

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.

CAUTION:
When you use this camera, the socket-out-
let shall be installed near equipment so
as to disconnect easily.
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.
