I'm trying to use RS232-to-USB to read from Sartorius analytic balance CP225D. I built a program using the Sartorius-SBI drivers from NI.
However, whenever I run the program, it always gives the error 1073807339. Sometimes, I can obtain several correct measurement data and then it suddenly outputs error.
Alternatively, we have been using the software called Winwedge (http://www.taltech.com/winwedge) to read data from the balance and it has actually been working. I'm working on the Labview program because I need to synchronize multiple instruments and Winwedge is not going to help with that. That said, I believe the program is not in the balance, and I've matched baud rate, parity, data bits and stop bits in each program. But it still doesn't work.
Can anyone suggest what could be wrong?
