RGB/YUV output connector — Connect an RGB (RGBHV, RGBS, RGsB) or YUV
component (R-Y, Y, B-Y) display device to this female 15-pin HD connector. RGB or YUV
color space is available on this buffered output.
g
Audio output connector — Connect an audio device to this female 5-pole 3.5 mm
captive screw connector for balanced or unbalanced analog audio output. Wire the
connector as shown below.
Do not tin the wires!

Audio Output Connector Wiring
CAUTIONS:
•
The length of the exposed wires in the stripping process is critical.
The ideal length is 3/16 inches (5 mm). If the exposed portion is
longer, the wires may touch, causing a short circuit between them.
If
the exposed wires are shorter, they can be easily pulled out, even if
tightly fastened by the captive screws.
•
Do not tin the wires. Tinned wire does not hold its shape and can
become loose over time.
•
For unbalanced audio, connect the sleeves to the ground contact.
DO NOT connect them to negative (–) contacts.
h
RS-232 connector — Connect a host device such as a computer or touch panel control
system to the Tx, Rx, and _ (ground) pins of this 5-pole captive screw connector for
serial control of the DVC by SIS commands (see “
on the next page for information on wiring this port). The first and second pins of this
connector are not used. The default protocol for this
port is 9600 baud, 1 stop bit, no parity, and no flow
control.
Daisy-chain Connection
The FOX 3G DVC can be connected to up to three
FOX 3G DVC or FOX 3G HD-SDI units through the
Buffered Loop-through port of the fiber optic Input
connector. Connect a fiber optic cable from the Tx
(loop-through) port of the DVC to the optical Rx
connector of the next FOX 3G device in the chain. All
receivers in the daisy-chain must be compatible; that is,
they must be all SM or all MM models, connected with
the appropriate fiber optic cable.
NOTE: Ensure that you use the proper fiber cable for your
connections. Typically, singlemode fiber cable has
a yellow jacket and multimode fiber cable has an
orange or aqua jacket.
