•  RX – RS-232 Receive. Blinking rate and intensity will vary with baud rate. 
•  HDBT – Lights when HDBaseT RJ-45 has proper connection between an RX/TX pair. Blinks

Rear Connections 
•  24V DC – Power connector for 15 watt 24VDC power supply. Note only 1 supply is required to 
power both units. Either side can send power to the other unit. Note if LAN POE is utilized the 
24VDC supply is not required. 
•  IR – Plug the IR receiver or emitter into this port. It will auto detect the mode of operation 
required. 
•  RS-232 – Connect RS-232 device up to 115k baud. 
•  HDBaseT – Connect CAT 5e/6/7 cable. Shield cable is not necessary unless the environment 
has a lot of electrically noise. 
•  HDMI Input – Plug HDMI cable from source device like a BluRay player. Note the HDMI cable 
should be rated for the bandwidth you are using. 
•  LAN1/2 – 10/100 LAN connection. LAN1 can use POE from a POE switch to power both the 
RX and TX units. Note: HDBaseT can only transmit 10T from the LAN.   
Note: Some POE switch do not supply the full 15.4watts per port. Verify the total power rating of the switch. It should 
be at least 15.4W x (number of ports).
