(2/38) 4. Communication Format The command packet consists of four parts, Header, Message, Check code and Delimiter. Sequence of a typical procedure to control a monitor is as follows, [A controller and a monitor, two-way communication composition figure] 4.
(3/38) 4 th byte) Source: Source equipment ID. (Sender) Specify a sender address. The controller must be ‘0’(30h). 5 th byte) Message Type: (Case sensitive.) Refer to section 4.2 “Message block format” for more details. ASCII 'A' (41h): Command ASCII 'B' (42h): Command reply.
(4/38) 3 ） Set parameter The controller sends this message to change a setting of the monitor.
