CR (0Dh): End of packet Step 4. The monitor replies with a message for confirmation. Header SOH-'0'-'0'- Monitor ID -'F'-'1'-'2' Message STX-'0'-'0'-'0'-'0'-'1'-'0'-'0'-'0'-'0' -'0'-'6'-'4'-'0'-'0'-'5'-'0'-ETX Check code Delimiter BCC CR 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'. 'F' (46h): Message Type is "Set 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): Brightness max value is 100(0064h). '0'-'0'-'5'-'0' (30h, 30h, 35h, 30h): Received a Brightness setting was 80(0050h) . ETX (03h): End of Message Check code BCC: Block Check Code Refer to the section 4.5 "Check code" for a BCC calculation. Delimiter CR (0Dh): End of packet  Repeat Step 1 and Step 2, if you need to check the Brightness setting. (Recommended) Step 5. Request the monitor to store the Brightness setting. (Save Current Settings Command) Header SOH-'0'-Monitor ID-'0'-'A'-'0'-'4' Message STX-'0-'C'-ETX Check code Delimiter BCC CR Header SOH (01h): Start Of Header '0' (30h): Reserved Monitor ID: Specify the Monitor ID which you want to store the setting. Ex.) If Monitor ID is '1', specify 'A'. '0' (30h): Message sender is the controller. 'A' (41h): Message type is "Command". '0'-'4' (30h, 34h): Message length is 4 bytes. Message STX (02h): Start of Message '0'-'C' (30h, 43h): Command code is 0Ch as "Save current settings". ETX (03h): End of Message Check code BCC: Block Check Code Refer to the section 4.5 "Check code" for a BCC calculation. Delimiter CR (0Dh): End of packet 6.2. How to read the measurement value of the built-in temperature sensors. MultiSync X461UN /X461HB /X431BT /P401 /P461 /P521 /P701 /S401 /S461 /S521 and MULTEOS M401 /M461 /M521 have three built-in temperature sensors. The controller can monitor inside temperatures by using those sensors with external control. (13/50)
