2. RS-232
Atlona Technologies’ switcher can be controlled via the RS-232 serial control port to allow for interfacing to a
PC, 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 unit needs to be controlled via the front panel in addition to the RS232 control, you should
party control system.
