4.3 CATx Remote Unit
1. DC 5V: Connect from 5V DC power supply into the unit and connect the adaptor to an AC
outlet.
2. IR RX: Connect to the IR Receiver for IR signal reception. Ensure that remote control
being used is within the direct line-of-sight of the IR receiver.
3. IR TX: Connect the IR Blaster cable included in the package for IR signal transmission.
Place the IR blaster in direct line-of-sight of the equipment to be controlled.
4. CAT5E/6: Connect the CAT input of the Remote Unit to the CAT output of the transmitter
(SPLITMUX) using CAT5E/6/6a/7 cable.
5. HDMI OUT: Connect the HDMI input port of your display such as an HDTV.
6. LOCK LED: This LED will illuminate when the HDMI signal from the transmitter is stable.
7. Power LED: This LED will illuminate when the device is connected with power supply.
8. Coaxial OUT: Connect to the audio amplifier with coaxial cable.
9. ARC : Switch the ARC switcher to enable or disable the ARC function.
ARC function : In order to use ARC, your HDTV must support this function.
When you enable the ARC function (switch in "ON" position), the coaxial of the
receiver will output the audio signal of the current HDTV display. If you switch the
input at the display to view the signal from a source connected to a different input on
the display (different than the signal from your Remote Unit), the audio from that
source will play back through the amplifier connected to the Coaxial of the Remote
Unit.
When disabled (switch in "OFF" position), the coaxial will only output the HDMI source
(DVD, set-top-box, etc) audio signal from the SPLITMUX.
