How to Resolve IR Code Confl icts

In the event that IR commands from other remote controls confl ict with the 
supplied RMT-2IR remote control, changing the remote channel will alleviate 
this issue. The RMT-2IR remote control and the 2x1 DisplayPort KVM both have 
banks of DIP (Dual Inline Package) switches for confi guring the remote channel 
that both units use to communicate. These settings must exactly match each 
other for proper operation. 

The DIP switch bank on the RMT-2IR is located underneath the battery cover. 
DIP switch banks for the 2x1 DisplayPort KVM are located on the underside of 
the unit beneath a black piece of metallic tape. Switches 1 and 2 on the RMT-2IR 
directly correspond to DIP Switches 1 and 2 on the 2x1 DisplayPort KVM. Only 
switches 1 and 2 (of 4 in that bank) are used for IR Code settings.
