Code distributor for control of American Dynamics RS-422 domes.
The code distributor shall provide a minimum of 16 RS-422 outputs, configured in groups of four. Each group must be independent of one another and provide a means for setting blocks of address ranges without accessing internal switches or jumpers. Each group shall provide all of the camera site information, including pan, tilt, focus, iris, zoom and auxiliary information, for up to 99 camera sites and conform to American Dynamics RS-422 protocol.
Each output must be capable of transmitting and receiving over two, 22 gauge shielded twisted pairs (STP) of conductors up to 10 domes in a daisy-chain configuration. The total distance from the code distributor to the last dome in a daisy-chain shall be at least 1000 meters (3280 feet). In addition, each group must be capable of connection to full duplex RS-422 fiber optic transceivers.
The input to the code distributor shall be provided by any one of a variety of matrix switcher/controller systems and be either a 125 kbps high-speed data or an AD Manchester control code output. For ease-of-connection, a looping pair of BNC connectors shall be provided for the high-speed data line and a removable “euro-style” terminal strip for the AD Manchester control code line.
The code distributor shall provide quick-connect screw terminals and diagnostic LEDs facilitate efficient installation and service. The LEDs shall provide visual indicators for confirmation of power, alarm, and control code status. The code distributor shall be capable of mounting to the front or rear of equipment racks, or flat on a wall or horizontal surface.
The code distributor shall be capable of receiving up to four alarms from each remote dome. Receipt of such, shall be from the same two shielded twisted pairs that are utilized for transmitting and receiving camera site information. No additional cabling from the domes shall be required. The code distributor shall be capable of transmitting the dome alarm information in simple ASCII format with a 1200, 2400, 4800, or 9600-baud selective baud rate to a matrix switcher/controller system via an RS-232 output. The code distributor shall provide Form C relay outputs and an Alarm LED that activate when an alarm input is active on any dome connected via the respective code distributor.
An RS-232 input shall also be provided for cascading multiple code distributors and/or alarm interface units. For ease-of-connection, a pair of 8-pin modular RJ-45 connectors and associated cables shall be provided. The RS-232 output shall be compatible with three wire, 18 AWG, shielded-wire for a distance of up to 300 meters (1000 feet).
The code distributor shall be capable of storing up to 16 presets for suitably equipped SpeedDome Ultra or SpeedDome Optima programmable camera domes.
The code distributor shall be an American Dynamics AD2083-02B (120 VAC), ADS2083 02B-1 (230 VAC) or equivalent.
