*Some IR repeater systems are designed to work only with their own IR 
blasters, and a common ―workaround‖ is to cut these blaster cables and add a 
3.5mm plug on the end. In some cases, repeater systems will have noise that 
prevents signals from being decoded. 
RS-232 Connection Details
The serial port is wired as a DCE device, and should be connected to a 
computer‘s RS-232 port with a straight through cable. Connection to most 
control systems should be with a straight through type serial cable, such as the 
cable provided with the matrix switch. For the command protocols, see the 
Serial Protocols section of this guide.
