Fiber optic connector —
For one-way video, audio, and serial communication from
the FOX T USW 103 to a receiver, connect a fiber optic cable between the Tx port on
the FOX T USW 103 and the Rx port on a receiver.
To return serial data from a receiver to the FOX T USW 103 or for HDCP-compliance,
connect a fiber optic cable between the Rx port on the FOX T USW 103 and the Tx port
on the receiver (see
Wiring for Fiber Communication
NOTES:
•
Ensure the proper fiber optic cable is used. Typically, singlemode fiber optic
cable has a yellow jacket and multimode fiber optic cable has an orange or aqua
jacket.
•
Only one fiber optic cable, transmitter-Tx-to-receiver-Rx, is required for video,
audio, serial command transmission, but the HDMI signal output on the receiver
will not be HDCP-compliant and the FOX T USW 103 will not receive RS-232
reports from the controlled device.
The Link LED indicators light when there is light presence on either fiber optic port.
