④ FW: Micro-USB port for firmware upgrade.
⑤ HDMI Out: Type-A female HDMI output port to connect HDMI display (e.g.TV).
⑥ Audio Breakout: If the ARC mode is OFF, the Toslink connector is connected to
speaker or amplifier for HDMI source audio de-embedding. Note that if the ARC
mode is ON, this port has no audio output.
⑦ IR In: 3.5mm jack to connect the IR receiver for IR pass-through.
⑧ IR Out: 3.5mm jack to connect the IR emitter for IR pass-through.
⑨ RS232: 3-pin terminal block to connect the RS232 control device (e.g. PC) or a
third-party device to be controlled.
⑩ HDBT In: RJ45 port to connect the HDBT output port of switcher/transmitter by
CATx Ethernet cable. The LINK LED illuminates orange when there is a valid
HDBaseT link between the switcher/transmitter and the receiver. The HDCP LED
illuminates green when the video contains HDCP content.
⑪ DC 24V: DC connector for the power adapter connection. If the
switcher/transmitter is connected to the power adaptor, the receiver doesn’t need
to connect power adaptor due to the HDBT output port of switcher/transmitter
supports 24V PoC output.
