RS232

The Atlona AT-PROHD82M switcher can be controlled via the RS-232 serial control port to allow for interfacing to a PC, or similar third party control system.

The serial communication parameters are 9600 baud, 8 bit no parity and 1 stop bit. This is often referred to as 9600 8N1. When the unit recognizes a complete command it will perform the requested action. There is no delimiter character required.
