RS-232 SERIAL INTERFACE PROTOCOL COMMANDS ( Ethernet / RS-232 Control driver V2.0 )
The HD-88K 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.
