C.4 Signal Distribution Unit

CONNECTION TO MAIN BAY

The Distribution unit is supplied with a 3 m long (10 ft) multiconductor cable with 9-pin D-type connectors. Power to the unit is provided by the Allegiant's main bay using the supplied cable. The cable should not be extended so it is recommended that the unit be located close to the main bay.

DISTRIBUTION OUTPUTS

Only shielded twisted pair wire should be used between the Distribution unit and the camera site receiver/drivers. Connection to the Distribution unit is made to removable screw terminal type blocks. Each output is rated to handle up to eight receiver/driver loads as in a daisy chain configuration to a maximum of 1.5 km (5000 ft) using a 18 gauge wire (Belden 8760 or equivalent).

C.5 Receiver/Drivers

CODE INPUT

The code input is supplied by the shielded twisted pair cable from the Signal Distri- bution unit. This is connected to a removable screw terminal type block which has provisions for “looping” the code cable to another receiver/driver.

OUTPUT CONNECTIONS

All pan/tilt and lens connections will require multiconductor cable. Refer to the appropriate specification sheet for cable gage, number of conductors required, and maximum distances allowable. The lens cables and any pre-position cables should be kept shielded from other signal wires to minimize interference.
