6.2. How to read the measurement value of the built-in temperature sensors.
Target displays 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.
Header
SOH (01h): Start of Header
'0' (30h): Reserved
Monitor 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.
Message
STX (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 meaning
01h: Sensor #1
02h: Sensor #2
03h: Sensor #3
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 for confirmation.
Header
SOH (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.
Message
STX (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.
'0'-'0'-'0'-'3' (30h, 30h, 30h, 33h): Number of temperature sensors are 3 (0003h).
'0'-'0'-'0'-'1' (30h, 30h, 30h, 31h): temperature sensor is #1.
