b 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

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

ﬁgure 3 for how to wire this connector).

Do not tin the wires!

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
