Read Board Temperature

This command returns the temperature at the optional 7409TC termination board. Useful for

monitoring the temperature of thermocouple reference junctions, this function is also a good

debugging aid during 518 installation. The returned temperature value is scaled to 0.10 degrees

C/bit.

If no 7409TC is connected to the 518, the Read Board Temperature command will return a

meaningless value.

COMMAND: (64)

RESPONSE: (BOARD TEMP MSB), (BOARD TEMP LSB)

EXAMPLE:

‘ Read and display the 7409TC temperature in degrees F:

CALL Send518Byte (BasePort%, 64) ‘send opcode to 518

Temp! = Read518Word (BasePort%) / 10! ‘read response & convert to degrees C

DegreesF! = 1.8 * Temp! + 32.0 ‘convert to degrees F

PRINT DegreesF! ’display temperature on CRT
