RMT-16IR REMOTE CHANNEL CONFIGURATION
Why would I need to change the remote channel?
In some instances, the 8x4 CAT-5 Matrix for HDMI may use IR codes that confl ict 
with other IR remote control devices. The unit may switch inputs when another brand 
IR remote control is used or the RMT-16IR may cause other brand IR controlled 
devices to behave unexpectedly.
I am experiencing the issues listed above. What do I do?
In these cases it is recommended to change the IR channel that the RMT-16IR 
remote control and the 8x4 CAT-5 Matrix for HDMI use. The IR channel is confi gured 
independently on the RMT-16IR remote control and the 8x4 CAT-5 Matrix for HDMI 
but the channel selection must match on both units for proper operation.
How Do I change the Remote Channel?
There are service DIP switches on the RMT-16IR remote control and also inside the 
8x4 CAT-5 Matrix for HDMI. Use the diagrams below to locate and change the IR 
channel to one that is not the default. Remember that the channel must match on 
both the unit and remote control for successful operation.
