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.

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.

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-C1480U Class 2 only

TK-C1480E Isolated power supply only

TK-C1481EG (AC230V)

Y/C OUT
