Instrument Driver for the infrared thermometer Chino IR-AH

[LuGO]

Any one out there has experience with this instrument? It communicates through the RS-232 port.

Thank you!

Hi Lugo:

I could not find any instrument drivers for this instrument, but you can always just use VISA for communication. In LabVIEW, if you go to Help->Find Examples, then search for serial you will find the Basic Serial Write and Read example. This may help you out.

Thank you Emilie,

I doubtfully asked the vendor for the communication manual and very kindly it was sent to me (I didn’t think they would make it available because they sell a data logger program for ~$200). In any case I will try your suggestion very soon. In fact I tried after receiving the manual, but ran into some problems.

Perhaps you can help me with this one also.

The communications parameters are (see attached manual):

Speed: 9600 bps
Start bit: 1 bit
Data length: 7 bits
Parity: Even
Stop bit: 1 bit
Character code: ASCII
BCC: none
Data transmission procedure: none

The problem is with what they call “start bit”. There is not such thing in the serial port initialization. Do you know if this means that the data length is 8 bits?

I have been trying several combinations but so far the data is not coming back. Thank you again for all your suggestions.

Setting data bits equal to 7 should work. I suspect that your problem is in formatting the command string. The format specifies STX+Command+SubCommand+Data+ETX+ETB+CR+LF. The STX,ETX,ETB,CR,LF are control codes and you cannot, for example enter the string "STX". STX is hex02 or CTL+B. ETX is hex03 or CTL+C. ETB is hex17 or CTL+W. CR is hex0D, and LF is hex0A. You can set your string control in LabVIEW for hex display or '\' Codes display. The '\' code equivalents are: STX=\02, ETX=\03, ETB=\17, CR=\r, LF =\n.
