RS-232 SERIAL INTERFACE CONNECT a PC or CONTROL SYSTEM. VERSION COMPATIBLE
RS-232
The 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 RS-232 control, you should regularly poll the unit status to ensure the control system accurately
refl ects the current settings.
