Page 20: Protocol 2000
Protocol 2000 10 Protocol 2000 The LTM-4x4HDSDI is compatible with Protocol 2000 (version 0.46) (below). This RS-232/RS-485 communication protocol uses four bytes of information as defined below. For RS-232, a null-modem connection between the machine and controller is used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit. -

- Page 24 Protocol 2000 NOTE 6 – If INPUT is set to 127 for these instructions, then, if the function is defined on this machine, it replies with OUTPUT=1. If the function is not defined, then the machine replies with OUTPUT=0, or with an error (invalid instruction code).
- Page 25 Protocol 2000 For example, to connect input 4 to output 3 after a delay, send HEX codes (set for delayed switch) (switch code) then, after the required delay, send HEX codes (execute delayed switch) to implement the switch. NOTE 19 – After this instruction is sent, the unit will respond to the ASCII command set defined by the OUTPUT byte. The ASCII command to operate with the HEX command set must be sent in order to return to working with HEX codes.
