ST-FOUSB4K-18GB-LC is an Optical HDMI Extender (XTENDEX) that overcomes the length restrictio n of standard
HDMI cables by using duplex single mode optical fiber to send high definition audio and video signals over distances of
up to 2km. It also supports USB extension for KVM applications requiring keyboard and mouse. Using built-in selection
switches, you can choose to 1) extend RS232 , 2) extend an IR remote control or 3) extend keyboard and mouse
functions from a PC. When extending RS232 you can transfer RS232 (up to 115kbps) in both directions, allowing you
to connect serial devices such as touch screens and barcode scanners.

IR Function:
The IR Emitter is used to send the control signal to the video source. It connects to the "IR Tx" port on either the
XTENDEX Transmitter or the XTENDEX Receiver. The IR Emitter must be positioned with 10 degrees horizontally
or vertically of the IR receiver on the video source.
The IR Receiver is used to receive and send the IR control signal from the Remote Control for the video source. It
connects to the "IR Rx" port on either the XTENDEX Transmitter or XTENDEX Receiver. The IR Receiver should be
positioned such that the Remote Control can send a signal within 55 degrees horizontally or vertically of the IR
Receiver.
