The CM9760-CDU-T code distribution unit is a 16-channel RS-422
transmit-only (two data wires and ground) data distribution unit. It
can be used with any system that uses RS-422 serial
communications. The CDU is used to install pan/tilt and dome
receivers in a “star,” or “home run,” configuration.
The unit is rack/wall mountable and is only 6 inches (15.2 cm) deep.
In addition to the 16 lines available for output with one unit, eight
CDUs may be daisy-chained. This allows 128 receivers (that support
128 address settings) to be connected on a single SERCOM port.
The remote devices can be located as far as 4,000 feet (1,219 m)
away from the controller, depending on the physical parameters of
the connection.
The unit is ideal for use on larger switching systems where it
becomes desirable to “home run” the RS-422 data lines for
controlling pan/tilt or dome receivers.
