infrared sensor serial

[boryszew]

Help,
I use an infrared sensor from Impac (IN 510). it is connected to my computer by RS232 and with the program given
by the company it works perfectly.
Now, I want to have the information through labview, but it doesn't works.
The measurment and automation programm seems to see the COM port. But it always returns me BFFF0015 when I test it.
This is the timeout error.
Helpppp

Can you post your code and a manual for the instrument?? You could also try portmon to watch the datastream of the program from the company.

Thanks for your answer!

I use the code given in exemple, And I tried several other codes given in this forum to make a check up of my serial connectivity.

Everytime it was the same, timeout error!

Sorry but the user manual is only on paper. The protocol is like that:

Send: 00ms (for reading)

and it should return:

YYYYY

This is a pdf file for a 500 level instrument.

Look at page 28 of 32. It looks like you need to add a <CR> to your string before transmitting. It also mentions a UPP Universal Pyrometer Protocol.
