Coaxial cable

Connecting a RG-59coaxial cable.

If a RG-11coaxial cable is used it cannot be con- nected directly to the terminal board. To use such a cable, connect a RG-59cable to the camera and then connect the RG-11cable to the RG-59cable.

Treat the extremity of the coaxial cable as shown below before connecting it.

Fold back the mesh wires and secure them with insulation tape in order to prevent them from becoming loose and thus causing a short circuit.

The figures inside the brackets ( ) are the dimensions

when the coaxial cable is distributed from the side of the cover. (Unit : mm)

If the cable is extended, the signal attenuation is increased, the resolution drops and the noise increases. Should it be required to extend the cable, use a thicker cable or a ca- ble length compensator.

To lead the coaxial cable through the cap on the side of the cover, change the positioning of the cable plate as shown below.

Maximum applied voltage: 30 V DC or 24 V AC

Maximum applied current: 2 A

Contact life: 200,000 times of operation

•The ALARM 2 and ALARM 3 ter- minals output open-collector sig- nals insulated by photocouplers.

The terminal is ON in the alarm sta- tus.

As these terminals are provided with polarity, make sure that the voltage at the + terminal is higher than that at the – terminal.

Do not apply inverse voltage to pre- vent damage of these terminals.

Strip the coating of each cable by about 4

mmbefore inserting it. After connecting all of the cables, turn the screws on the side to fasten the connectors.

It is recommended to use a 4-core (a pair) twisted pair cable (0.65) or a twisted pair cable of category 3 or higher which is used for a Ethernet.

Cables with a thickness between 16 AWG and 26 AWG can be used. Connect the control signal cables so that the TX+ and TX- signals form a pair and the RX+ and RX- signals form another pair.
