Input connector and LED —
NOTES:
•
The input (right-hand) LC connector for transciever block 1 is the only
functional input connector.
•
The right-hand LC connectors are not functional for transceiver blocks 2
through 8.
Optical transceiver block 1 Input connector —
For one-way video, audio, and serial
communications from the transmitter to the FOX DA8 (for distribution to the receivers,
connect a fiber optic cable to the block 1 optical transceiver input (right-hand) LC connector.
Connect the far end of this fiber optic cable to the sending connector on the transmitter
or
other compatible Extron device
.
Optical transceiver block 1 Input LED —
When lit, the link is active (light is received
from the transmitter).
NOTES:
•
The input (right-hand) LED indicates the light link for transceiver block 1.
•
The right-hand LEDs for transceiver blocks 2 through 8 may light, but do
not indicate an input to that connector.
c
Output connectors and LEDs —
Connectors — For one-way video, audio, and serial communications from the FOX DA8
to the receivers, connect up to eight fiber optic cables to the output LC connectors on
transceiver blocks 1 through 8.
Connect the far ends of these fiber optic cables to the receiving connectors on the
receivers or other compatible Extron devices.
LEDs — These LEDs are always lit, whether the output is active (unmuted) or not.
d
RS-232 port —
For serial control of the DA, connect a host device, such as a computer,
touch panel control, or RS-232 capable PDA, via this 3-pole captive screw connector (see
for
how to wire this connector).
Do not tin the wires!

RS-232 Connectors
NOTES:
•
The length of exposed wires is critical. The ideal length is 3/16 inches
(5 mm).
•
If the stripped section of wire is longer than 3/16 inches, the exposed
wires may touch, causing a short circuit.
•
If the stripped section of wire is shorter than 3/16 inches, wires can be
easily pulled out even if tightly fastened by the captive screws.
This port is RS-232 only, with the following protocols:
z
9600 baud
z
no parity
z
8 data bits
z
1 stop bit
z
no flow control
