Step 2 — Input and Output Connections
a. Connect an HDMI video source to the HDMI input connector.
b. If desired, connect an HDMI video display to the Loop-Thru connector for a local display.
c. Connect an audio input device to either the Audio 3.5 mm mini jack or the Audio 5-pole captive screw connector.
See the drawing below step 2d to make connections on the captive screw connector.
d. For optional returned audio, connect an audio output device to the Audio Return Out 5-pole captive screw connector.
See the drawing below to make connections on the captive screw connector.

Tip
ATTENTION:
• For unbalanced audio, connect the sleeves to the
ground contact. DO NOT connect the sleeves to the
negative (–) contacts.
• Pour l’audio asymétrique, connectez les manchons au
contact au sol. Ne PAS connecter les manchons aux
contacts négatifs (–).

NOTE: For returned audio, above, you must also do the following:
• Connect an audio input device to the Audio Return In 5-pole captive screw connector on the receiver.
• Install the optional Receiver-Tx-to-transmitter-Rx cable in step 3b.
e. If you want the FOX II units to pass serial or IR data or control signals, such as for serial
control of a projector, connect the host device to the transmitter and the peripheral device to
receiver via the Over Fiber 5-pole captive screw connector.

f. For remote monitoring of the status of the Rx optical link, connect a locally constructed or obtained device to the two
rightmost Alarm poles of the Alarm and Remote RS-232 5-pole captive screw connector. The unit shorts both poles
RS-232
together when no light is detected.
Tx Rx G
NOTE: The transmitter Alarm port reports the status of the link from the receiver.
g. For remote control of a unit and loading rmware, connect a host device, such as a computer or control system, to either of the
following ports:
ALAR
Configuration port
— The front panel mini USB connector.
NOTE: Extron recommends performing firmware updates via the Configuration port only.
Remote RS-232 port
— The rear panel Remote RS-232 port, the 3 leftmost poles of this 5-pole captive screw connector.
The protocol for the Remote port is as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no ow control
Step 3 — Throughput Connections
NOTE: See the two fiber cable connection drawing at right. You can connect the transmitter to a compatible receiver
in one of two ways:
• One way (transmitter to receiver) only, perform step 3a.
• Two way (transmitter to receiver and return), perform steps 3a and 3b.
a. Connect the ber between the Tx port on the transmitter and the Rx port on the receiver (
b. If you want the receiver to return serial data (such as responses from a controlled device) to the transmitter, connect
a cable between the Tx port on the receiver and Rx port on the transmitter (2).
Tx Link and Rx Link LEDs — When lit, the link is active (light is output [Tx] or received [Rx]).
NOTE: The Link LEDs indicate transmission of light only, not whether there is data encoded in the optical link.

Power LED — Indicates that power is applied to the unit.
Video LEDs —
Signal LED — Lights when the unit detects an input video signal.
CONFIG
HDCP LED — Lights when the input signal is HDCP encrypted.
Audio LEDs —
Input LED — Lights when an analog audio or PCM digital audio signal remains above -35 dBV. The LED goes unlit if the audio signal
level drops below the threshold for 10 seconds or longer.
Return Out LED — Lights when analog audio is present on the transmitter Return Audio Output connector.
EDID
EDID Select rotary switch — Set this switch to one of the positions shown in the table below to select the source of the DDC or a specic
resolution.
Position 0 — An EDID that has previously been captured from a connected display or manually imported via an SIS command or the
Product Conguration Software.
Position 1 — The EDID is selected via the remote or USB port on the transmitter only, using an SIS command or the Extron Product
Conguration Software.
Position 2 — Use the EDID from the display connected to the receiver.
