HDMI 4x4 Matrix Switcher User Guide 5
Connecting with the computer
The switcher can be controlled via a computer COM port. However, another
scenario is to use a third-party control system such, as Clare Controls, Crestron, or
Control4. The RS232 protocols required for these systems are listed in the section
“Communication protocol and command codes” on page 10. Use a straight-thru
RS232 cable (non-null modem) to connection to these systems, unless otherwise
stated by the control system’s manufacturer.
