AB-4148 INSTRUCTION & OPERATION MANUAL
The Matrix 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 unit needs to be controlled via
the front panel in addition to the RS232 control, you should regularly poll the unit status to ensure the control system accurately reflects the
current settings.
