IV. Control Commands
6. Typical procedure example
The following is a sample of procedures to control the monitor, these are examples of "Get parameter",
"Set parameter" and "Save current settings".
6.1. How to change the “Backlight” setting.
Step 1. The controller requests the Monitor to reply with the current brightness setting and capability
to support this operation. (Get parameter)
Header Message Check code
Delimiter
SOH-'0'-Monitor ID-
'0'-'C'-'0'-'6'
STX-'0'-'0'-'1'-'0'-ETX BCC CR
Header
SOH (01h): Start of Header
'0' (30h): Reserved
Monitor ID: Specify the Monitor ID from which you want to get a value.
Ex.) If Monitor ID is '1', specify 'A'.
'0' (30h): Message sender is the controller.
'C' (43h): Message type is "Get parameter command".
'0'-'6' (30h, 36h): Message length is 6 bytes.
Message
STX (02h): Start of Message
'0'-'0' (30h, 30h): Operation code page number is 0.
'1'-'0' (31h, 30h): Operation code is 10h (in the OP code page 0).
ETX (03h): End of Message
Check code
BCC: Block Check Code
Refer to the section 4.3 “Check code” for a BCC calculation.
Delimiter
CR (0Dh): End of packet
Step 2. The monitor replies with current Backlight setting and capability to support this operation.
Header
SOH (01h): Start of Header
'0' (30h): Reserved
'0' (30h): Message receiver is the controller.
Monitor ID: Indicate a replying Monitor ID.
Ex.) When this byte is set to 'A', the replying Monitor ID is '1'.
'D' (44h): Message Type is "Get parameter reply".
'1'-'2' (31h, 32h): Message length is 18 bytes.
Message
STX (02h): Start of Message
'0'-'0' (30h, 30h): Result code. No error.
'0'-'0' (30h, 30h): Operation code page number is 0.
'1'-'0' (31h, 30h): Operation code is 10h (in the page 0).
'0'-'0' (30h, 30h): This operation is "Set parameter" type.
'0'-'0'-'6'-'4' (30h, 30h, 36h, 34h): Backlight max value is 100(0064h).
'0'-'0'-'3'-'2' (30h, 30h, 33h, 32h): Current Backlight setting is 50(0032h) .
ETX (03h): End of Message
Check code
BCC: Block Check Code
Refer to the section 4.3 “Check code” for a BCC calculation.
