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.
The unit does not send out a message when a value is changed from the front panel or by IR control. If the
switcher needs to be controlled in addition to the RS-232 control, you should regularly verify the unit’s status to
