Pelco Manual C2915M-E (08/05) [ 13 ]

Service Connection

The service connector allows a video monitor to be connected locally to the camera using a 2.5 mm plug to

composite video BNC cable.

Figure 6. Service Connector

NOTE: Inserting the plug into the service connector disconnects video from the composite BNC connector

on the rear panel of the camera.

To send composite video through the RJ45-10 connector:

1. Connect composite video out to pin 3.

2. Connect composite video ground to pin 2.

Manual Color/B-W Switch

The camera can be switched between color and black-white operation manually using an external switching

device. The remote switch should be connected to pin 4 and pin 7 and the switch must be connected in parallel

with a 10 kΩ resistor as shown in Figure 4. The cable length must be no more than 1,000 feet (300 meters).

Unshielded Twisted Pair (UTP)

Pins 5 and 6 allow video to be transmitted over unshielded twisted pair (UTP) wiring to equipment fitted with a

suitable receiver. Ensure that connection polarity is observed in relation to the connected twisted pair receiver.

To implement UTP, you must use 5-pair unshielded twisted cable, Cat5e, or an equivalent. The camera has a

built-in transmitter for UTP. However, you must provide a UTP receiver. Your maximum cable distance depends

on whether you install a passive or active receiver. When outputting composite video through the BNC or RJ45-

10, do not send UTP output to a passive UTP receiver. However it is acceptable to use an active UTP receiver

for UTP output in combination with the other video connections.

To send UTP video through the RJ45-10 connector:

1. Connect UTP+ video output to pin 6.

2. Connect UTP- video output to pin 5.

24 VAC/12 VDC Power Connection

Pins 8 and 9 allow connection to a power supply of 10.8 to 13.8 VDC (12 VDC -10% +15%) or 20.4 to 27.6 VAC

(24 VAC ±15%) at 50/60 Hz. Correct connections and polarity must be observed.

WARNING: When powering the camera via the RJ45-10 connector, ensure that the power

connections to the screw terminals on the rear of the camera are not used. The power supply

must be a UL Listed Class 2 isolated type.
