Audio Input connectors —
N
Connect an active input to only the 3.5 mm mini jack or
the captive screw connector, not both.
3.5 mm mini jack —
Plug a stereo mini plug into this connector.
5-pole captive screw connector —
Connect a balanced or
unbalanced stereo or mono audio input to this connector. The
connector is included with FOX 500, but you must supply the
audio cable. See figure 2-5 to wire a captive screw connector
for the appropriate input type and impedance level. Use the
supplied tie-wrap to strap the audio cable to the extended tail of
the connector.

N
The length of exposed wires is critical. The ideal
length is 3/16” (5 mm).
•
If the stripped section of wire is longer than 3/16”, the
exposed wires may touch, causing a short circuit.
•
If the stripped section of wire is shorter than 3/16”,
wires can be easily pulled out even if tightly fastened
by the captive screws.
N
See figure 2-6 to identify the tip, ring, and sleeve when
you are making connections for the transmitter from
existing audio cables. A mono audio connector consists
of the tip and sleeve. A stereo audio connector consists
of the tip, ring and sleeve. The tip, ring, and sleeve wires
are also shown on the captive screw audio connector
diagrams, figure 2-5 and figure 2-8.

The input audio level can be set via the front panel or RS-232
control. See chapter 3, "Operation", and chapter 4, "Remote

RS-232 Over Fiber port — If you want the
FOX 500 to pass
serial command signals to
the receiver, for serial control of a projector
for example, connect the host device to the
transmitter via three poles of this 5-pole captive
screw connector. See "Rear panel serial ports connections" on
page 2-16 to wire this connector.
N
If you connect only one fiber optic cable (item
,
on the next page), you will not receive reports from
the controlled device. To receive responses from the
controlled device, you must install two fiber optic cables.
N
The FOX 500 can pass RS-232 commands and responses
at rates up to 115200 baud.
h
Remote RS-232 port —
For serial control of
the transmitter, connect a host device, such as a
computer, touch panel control, or RS-232 capable
PDA, to the transmitter via three poles of this 5-pole
See chapter 4, "Remote Control", for definitions of the SIS
commands (serial commands to control the transmitter via
this connector).
i
Alarm outputs port — For remote monitoring of
the status of fiber optic link 2, connect a locally-
constructed or furnished monitoring device
to the transmitter via two poles of this 5-pole
captive screw connector. When the transmitter
does not detect a light link on fiber cable Optical 2 (optional),
pin 1 and pin 2 of this port are shorted together.
