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

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

containing too much jitter, such as a VCR
or videodisc playback signal.

• For details, consult a JVC authorized

dealer.
