INTRODUCTION 

The  AV-GM0463-S1 

HDMI  Extender  over  Single  Coax  with  RS-232

  boosts  up  your  HDMI 

transmission  range  up  to  90m  (295t)  in  HDTV  1080p  format  through  single  coaxial  cable. 
AV-GM0463-S1 is easy to install and works perfectly with Belden 1694A coaxial cables. Other coaxial 
cables can also work with AV-GM0463-S1 and the transmission distance depends upon the quality 
and  bandwidth  of  coaxial  cables.  In  addition,  AV-GM0463-S1  is  also  equipped  with  RS232  local 
loopout. This bonus feature allows users to rely on the same coax cable to have RS-232, such as TV 
and BD players, and AV-GM0463-S1 makes RS-232 control possible through only single coax cable 
along with high quality HDMI A/V signals. 

The  AV-GM0463-S1  includes  two  units:  transmitting  (AV-GM0463-S1[TX])  and  receiving 

(AV-GM0463-S1[RX])  units.  The  transmitting  unit  is  used  to  capture  the  HDMI  and  HDCP  input 
signals and carry the signals through only coaxial cable. The receiving unit is responsible for auto 
equalizing  the  transmitted  HDMI  multimedia  data.  The  transmission  range  between  the  sending 
and receiving units can be up to 90m (295t) under Full HD (1080p) with 7.1 channel audio.

  1x User Manual   

 

 

The length depends on the characteristics and quality of the coax cables. Higher resolutions 
and  longer transmission  distances require  low  skew  cables  for best performance.  Solid  and 
shielded coax cable such as Belden 1694A with metal 75ΩBNC connectors is recommended.
