(26/137)6.2. How to read the measurement value of the built-in temperature sensors.MultiSync P403/ P463 /P553 have three built-in temperature sensors.The controller can monitor inside temperatures by using those sensors with external control.The following shows the procedure for reading the temperatures from the sensors.Step 1. Select a temperature sensor which you want to read.HeaderSOH (01h): Start of Header'0' (30h): ReservedMonitor ID: Specify the Monitor ID which you want to get a value.Ex.) If Monitor ID is '1', specify 'A'.'0' (30h): Message sender is the controller.'E' (45h): Message Type is "Set parameter command".'0'-'A' (30h, 41h): Message length is 10 bytes.MessageSTX (02h): Start of Message'0'-'2' (30h, 32h): Operation code page number is 2.'7'-'8' (37h, 38h): Operation code is 78h (on page 2).'0'-'0'-'0'-'1' (30h, 30h, 30h, 31h): Select the temperature sensor #1 (01h).00h: No meaning01h: Sensor #102h: Sensor #203h: Sensor #3ETX (03h): End of MessageCheck codeBCC: Block Check CodeRefer to the section 4.5 “Check code” for a BCC calculation.DelimiterCR (0Dh): End of packetStep 2. The monitor replies for confirmation.HeaderSOH (01h): Start of Header'0' (30h): Reserved'0' (30h): Message receiver is the controller.Monitor ID: Indicates 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.MessageSTX (02h): Start of Message'0'-'0' (30h, 30h): Result code. No error.'0'-'2' (30h, 32h): Operation code page number is 2.'7'-'8' (37h, 38h): Operation code is 78h (in the page 2).'0'-'0' (30h, 30h): This operation is "Set parameter" type.Header Message Check code DelimiterSOH-'0'-Monitor ID-'0'-'E'-'0'-'A'STX-'0'-'2'-'7'-'8'-'0'-'0'-'0'-'1'-ETXBCC CRHeader Message Check code DelimiterSOH-'0'-'0'-Monitor ID-'F'-'1'-'2'STX-'0'-'0'-'0'-'2'-'7'-'8'-'0'-'0'-'0'-'0'-'0'-'3'-'0'-'0'-'0'-'1'-ETXBCC CR
