7.2 Installation of Sony Cameras
Sony VISCA controlled cameras can either be connected using a RS-232 or
RS-422 serial connection and are selectable on the bottom of each camera with
dip-switches. With a RS-232 connection, the maximum cable length can be
extended to 15 meters (50 feet), while the RS-422 connection extends this further
to 1200 meters (4000 feet). It is important to set the baud rate of each camera to
9600 bps, for both a RS-232 and a RS-422 connection, this is also selectable on the
bottom of each camera with dip-switches.
There are no COM ports out of the Broadcast Pix Server, a 4/8 port USB extender
(Edgeport) is required to control cameras serially. Sony PTZ cameras also support
daisy chain as well as star configurations using a USB to Serial Edgeport. If using the
USB extender (Edgeport) ensure that the port flags are set to RS-422, as described in
section 6.5.2.
You may either loop cameras to each other in a 422 daisy chain, have all cameras
connect to the Server with several serial ports using a star configuration, or have a
combination of both scenarios.
Below is the wiring diagram needed for serial cables connecting Sony Cameras to the
RS-422 COM ports.
