Broadcast Pix Slate 1000G Installation Planning Guide - 2012
Page
For installations needing longer runs you may also use an RS-422 configuration, which extends
the maximum length to 1,200 meters (4,000 feet). Note, not all Sony VISCA cameras
support RS-422 communication. When using an RS-422 connection, there are 3 configuration
options, and depending on installation needs, you may connect cameras in a daisy
chain, star or star/daisy chain combination.
The single camera or daisy chain configuration, (option # 811) includes a DB 9-pin RS-232 to
screw terminal RS-422 converter, which plugs into the workstation in either COM 1 or COM 2.
From the screw terminal you may connect your first camera using the 9-pin connector plug
provided with the camera. From the same connector you may loop communication to the
rest of your cameras. See below for wiring diagram.
If controlling more than one camera, there is an optional 4 or 8 port Edgeport serial extender,
(option #814 or #818) to accommodate either star or star/daisy chain configurations. This
method is useful when needing to run long home run to various studios, from which you can
then daisy chain. Depending on your installation needs, this may save in cable runs.
