Switch the HOST/DEVICE USB CONTROL switch to left, then power off and reboot
the transmitter to set to USB Host mode. Meanwhile, switch the HOST/ DEVICE
USB CONTROL switch to right, then power off and reboot the receiver to set to
USB Device mode.
Mode 2 : USB reverse from RX to TX
Switch the HOST/DEVICE USB CONTROL switch to right, then power off and reboot
the transmitter to set to USB Device mode. Meanwhile, switch the HOST/DEVICE
USB CONTROL switch to left, then power off and reboot the receiver to set to
USB Host mode.
IR Pin Definition
IR Receiver and Blaster pin’s definition as below
Note : When the angle between the IR receiver and the remote control is ± 45 °, the transmission distance is 0-5 meters; when the angle between the IR receiver and the remote control is ± 90 °, the transmission distance is 0-8 meters.
Application Example
Mode 1 : eARC/ARC Application
The Audio Return Channel (ARC) in HDMI 2.1 enables a TV, via a single HDMI
cable or audio cable, to send audio data “upstream” to an A/V receiver, the
extender will continue the upstream audio all the way to the transmitter.
There it can be connected via HDMI ARC.
Note : Please press the eARC buttons on the front panel of the transmitter and receiver to enable the eARC/ARC function before operating the system.
Mode 2 : Ordinary Connection Application
Note : Please press the eARC buttons on the front panel of the transmitter and receiver to disable the eARC/ARC function before operating the system.
