8. CODE DISTRIBUTOR FOR CONTROL OF AMERICAN DYNAMICS RS-422
DOMES
A. 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.
B. 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.
C. 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.
D. 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.
E. 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.
