Hello,
I´ve developed a program to read and analyze data from a thermography camera (NEC San-ei 6T62). Unfortunately I get sometimes problems with the data communication via GPIB.
Frequently the communication doesn´t works. I can transfer data to random (e.g. 10) times, and while the next inquiry I get a timeout. And now, all instructions were leading to no results. The thermography camera doesn´t respond. LV shows an timeout error. I´ve chosen 5 seconds for timeout, and this is really enough, because when all works, data communication is finished under one second. If I send DCL now via the CLR-Vi, I get an error information on the camera.
Description of error (from the operation manual):
It can be:
(1) command code deviates from specification
(2) command parameter deviates from prescribed value, or number of parameters does not agree with number required
(3) incorrect delimiter
But, why do I get this error only when the thermography camera didn´t respond before? When I send DCL during communication works, I don´t get an error.
After receiving this error, sometimes it works, sometimes not.
Thanks for help.
Andy
