Fiber Optic Connector

DFiber 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 on page 7).

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.

RS-232 Over Fiber and Alarm Connector

ERS-232 Over Fiber port — To pass serial command signals to a receiver (for serial control of a projector, for example), connect a host device to the switcher via the leftmost poles (Tx, Rx, and G) of this 5-pole captive screw connector (see Wiring for RS-232 Over Fiber and Alarm Communication on page 8 for wiring configurations).

Alarm port — For remote monitoring of the status of fiber optic link 2, connect a custom or furnished monitoring device to the switcher via the rightmost poles (1 and 2) of this 5-pole captive screw connector (see Wiring for RS-232 Over Fiber and Alarm Communication on page 8).
