b
Input connectors and LEDs
Connectors — For one-way video, audio, and serial
z
communications from the transmitter to the FOX SW8
(for switching to the receiver), connect up to eight
fiber optic cables to the optical transceiver blocks
Input (right-hand) LC connectors.
Connect the far end of these fiber optic cables to the
sending connectors on the transmitters or other
compatible Extron devices.
LEDs — When lit, the link is active (light is received
z
from the transmitter).
c
Loop connectors and LEDs
Connectors — For unswitched (input 1 loops
z
through to output 1, input 2 to output 2, and so on),
one-way video, audio, and serial communications,
looped through from the switcher, connect fiber optic
cables to the Loop (left-hand) LC connectors on
transceiver blocks 1 through 7.
Connect the far ends of these fiber optic cables to the
receiving connectors on the receivers
compatible Extron devices .
LEDs — These LEDs are always lit (light is always
z
output to these connectors).
d
Output connector and LED
Connector — For the switched output one-way
z
video, audio, and serial communications, connect a
fiber optic cable to the Output (left-hand)
LC connector on transceiver block 8.
Connect the far end of this fiber optic cables to the receiving connector on the
receiver or other compatible Extron device.
LED — This LED is always lit (light is always output to this connector).

e
RS-232 port — For serial control of the switcher, connect a host device, such as a
computer, touch panel control, or RS-232 capable PDA, via this 3-pole captive screw
connector. Figure 3 shows how to wire this connector.
