②AUDIO MATRIX OUT/ARC: Eight 3-pin terminal blocks and eight Toslink connectors to
connect speakers or amplifiers for HDMI input audio de-embedding or HDBaseT output
audio de-embedding, and the eight Toslink connectors can also be used for ARC audio
output from HDBaseT receivers. They can make up an audio matrix to be set by front panel
buttons, GUI or RS232 commands.
③OUTPUT: Eight HDBaseT RJ45 outputs to connect the eight HDBaseT receivers, and eight
local HDMI ports to connect local displays.
④CONTROL:
RS232: 3-pin terminal block to connect the control device (e.g. PC) to control the matrix
switcher by RS232 commands.
IR EYE: 3.5mm jack to connect IR receiver to control the matrix switcher by the IR
remote.
FW: Type-A USB port for firmware upgrade.
TCP/IP: RJ45 port to connect the control device (e.g. PC) to control the matrix switcher
by GUI.
⑤RS232: Eight 3-pin terminal blocks to control the third-party devices base on RS232
pass-through feature. There is a one-to-one correspondence between the eight RS232 ports
and the eight RS232 ports of eight HDBaseT receivers.
⑥IR IN:
1~8: Eight 3.5mm jacks to connect eight IR receivers. Each IR input is associated with
the respective HDBaseT output and cannot be switched separately. It makes up a
bi-directional IR transmission with the IR OUT on the corresponding HDBaseT receiver.

⑨GROUND: Connect to earth to ensure the unit is well grounded.
Receiver Front and Rear Panel
①Power LED: The LED illuminates red when power is applied.
②ARC Mode: Press the button with paper clip or other sharp tool to enable the ARC mode,
and then the left LED illuminates blue. Press it again to exit the ARC mode and the LED is
off. When the ARC audio is selected as the audio source for the SPDIF output of matrix
switcher, the ARC mode will be enabled automatically.
③ARC Audio In: Toslink connector to connect ARC audio source device (e.g.TV).
④FW: Micro-USB port for firmware upgrade.
⑤HDMI Out: Type-A female HDMI output port to connect HDMI display (e.g.TV).
⑥Audio 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.
⑦IR In: 3.5mm jack to connect the IR receiver for IR pass-through.
⑧IR Out: 3.5mm jack to connect the IR emitter for IR pass-through.
⑨RS232: 3-pin terminal block to connect the RS232 control device (e.g. PC) or a third-party
device to be controlled.
⑩HDBT 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.
⑪DC 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.
