N
Ensure that you use the proper fiber cable for your
transmitter/receiver pair. Typically, singlemode fiber has
a yellow jacket and multimode cable has an orange jacket.
N
Only one fiber optic cable, transmitter Tx to receiver
Rx, is required for video, audio, and serial command
transmission. But, if you connect only one fiber optic
cable, or if your transmitter is configured to daisy-chain
the optical signal, system functionality is reduced. You
will
not
receive RS-232 reports from the controlled
device, and some Windows-based control program
functions and RS-232 commands will not work. To
receive responses from the controlled device and for full
functionality, you need to install both fiber optic cables
and leave the FOXBOX receiver in normal configuration
(Mode DIP switch 1 down).
Rx (required) —
For all one-way video,
audio, and serial communications from the
transmitter to the receiver, connect a fiber
optic cable to the Rx LC connector.
Connect the free end of this fiber optic cable
to the Tx connector on the FOXBOX 4G Tx
transmitter (item
f
on page 2-8) or to
any other compatible Extron FOXBOX 4G
device.
Tx (optional) —
Connect a fiber optic cable
to the Tx LC connector for either of the
following functions:
Normal configuration —
For all one-
way return serial communications from
the receiver to the Rx connector on the
transmitter
Daisy chain configuration —
For
daisy-chained video, audio, and serial
communications to the Rx connector on another receiver
N
The Tx connector emits light in either case and the Rx
port receives light.
Connect the free end of this fiber optic cable to either:
• The Rx connector on the FOXBOX 4G Tx transmitter
(item
f
on page 2-8) or to any other compatible Extron
FOX device
• The Rx connector on another receiver in the daisy
chain
j
RGB Output connector (FOXBOX 4G Rx VGA only) —
Connect an analog VGA - UXGA RGB video display to this
15-pin HD female connector.
N
You can set the receiver to output the desired video
format: RGBHV or RGsB. RGBHV is the default. See
chapter 3, "Remote Control".
k
DVI-I Output connector (FOXBOX 4G DVI only) —
Connect a
DVI video display to this DVI-I connector. See "DVI connector
(FOXBOX 4G DVI)" on page 2-13 for pin assignments.
N
The FOXBOX 4G DVI outputs only the digital signals
on the DVI-I Output connector. The analog pins on the
port are not connected.
l
Audio connector —
Plug an audio device into this stereo mini
jack connector.
m
RS-232 Over Fiber port —
If you want the
FOXBOX 4G to pass serial command signals to the
receiver, for serial control of a projector for example,
connect the host device to the transmitter via
the first three leftmost poles (Tx, Rx, and
_
) of
this 5-pole captive screw connector. See "RS-232 Over Fiber
connection" on page 2-14 to wire this connector.
N
If you connect only one fiber optic cable (item
o
,
below),
or you configure the receiver for daisy-chaining, you will
not receive reports from the controlled device. To receive
responses from the controlled device, you must install
two fiber optic cables and leave the FOXBOX receiver in
normal configuration (Mode DIP switch 1 down).
N
The FOXBOX 4G can pass RS-232 commands and
responses at rates up to 115200 baud.
n
Alarm outputs port —
For remote monitoring of
the status of fiber optic link 1, connect a locally-
constructed or furnished monitoring device to the
receiver via the two rightmost poles (1 and 2) of this
5-pole captive screw connector. When the receiver
does not detect a light link on fiber cable Tx, pin 1 and pin 2 of
this port are shorted together.
o
Fiber optic connectors and LEDs —
W
These units output continuous invisible light,
which may be harmful and dangerous to the eyes;
use with caution. For additional safety, plug the
attached dust caps into the optical transceivers
when the fiber optic cable is unplugged.
