5.1General

Code Merger units are supplied in an indoor rated enclosure designed to fit a standard EIA 19" rack. Install the unit in the rack using appropriate mounting hardware (not supplied).

Input connections to a Code Merger are made to any of its 9-pin D-type connectors. The pinouts of the supplied 2-meter (6 feet) data cables can be connected directly to the control code output connector of an Allegiant Series Matrix Switcher system. Remember to tighten all connector attachment screws at each connection point.

If the control code sources are beyond the length of the cable, or are not Allegiant systems, the data cables must be adapted as necessary, for connection to the control device. If desired, a user-supplied 9-pin D-type connector may be used for interfacing to the Code Mergers. Pinouts for the 9-pin connectors are described within this manual.

Connect shielded twisted pair cable (Belden 8760 or equivalent) between the camera site receiver/driver locations, and any of the 32/64 outputs provided on the rear panel of the Code Merger unit. The same data is generated from all outputs, thus it is irrelevant which one is used.

Eight (8) pairs of removable screw terminal blocks are provided, each having four (4) connection groups per block. Typically, a single camera site receiver/driver or AutoDome is connected to each output, but the biphase output of these units is rated to handle up to eight (8) devices, when connected in a daisy chain configuration, to a maximum of 1.5 km (5000 ft).

In a daisy chain connection, the cable is looped through each AutoDome camera or receiver/driver along the way. Only the last unit in the daisy chain connection must be terminated. The remaining receiver/drivers must have the terminating resistor removed when the looping cable is connected.

Select and maintain a wire color convention to avoid confusion at the various camera sites.

Example: White to "+", Black to "-", and Shield to "S".

Follow the standard installation instructions, provided with the AutoDome Camera or Allegiant Series Receiver/Driver unit, for setting device address and connecting the data cable to the unit.

Connect the AC power cord to an appropriate power source. The green Power LED on the code merger unit front panel should illuminate when power is applied.

5.2Camera Address Offset Feature

(effective May 2003, Date Code 0314)

Code Merger units contain an optional feature that can be used to offset the camera addresses for data being received by code merger inputs 2, 3, and 4. Input 2 can be set to offset addresses by 16, input 3 by an offset of 32, and/or input 4 by an offset of 48. This feature allows code mergers to be used in multi-device systems where some of the control devices do not support offset camera addresses of the data being generated. Refer to sample configuration diagrams for additional details.

The cover of the Code Merger must be removed to access the dip switch used for configuration of options. Follow the instructions below to set the camera address offset.
