HDMI switched output connector — Connect a display device to the female type A
HDMI output connector for local HDMI output for switched inputs 1, 2, and 3.
Selected Video Input HDMI Switched Output
VGA (input 1) On (no embedded audio or HDCP compliance)
HDMI (input 2 and 3) On
f
Fiber optic connector — For one-way video, audio, and serial communication from
the FOX T USW 203 to a receiver, connect a fiber optic cable between the Tx port on
the FOX T USW 203 and the Rx port on a receiver.
To return serial data from a receiver to the FOX T USW 203 or for HDCP compliance,
connect a fiber optic cable between the Rx port on the FOX T USW 203 and the Tx port
on the receiver (see Wiring for Fiber Communication on page 7).
NOTES:
• Ensure that you use the proper fiber optic cable. 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, and serial command transmission, but the HDMI signal output on the
receiver will not be HDCP-compliant and the FOX T USW 203 will not receive
RS-232 reports from the controlled device.
The Link LED indicators light when there is light present on the corresponding fiber optic
port.
