Garbage being displayed

[CJasnoch]

I am not exactly sure what is going on. We have a program that does some serial communication via RS485. The program works fine pre-build but when it is built I am getting odd characters (wing-ding type). It is on a different PC so maybe it is a driver issue with the RS485 card..

Anyone have an idea of why this would be?

What do the characters look like? (A screen shot would help)

What are the hex/decimal values that are being returned?

I've often seen this happen when Baud rates are incorrect.

Have seen such a behaviour (also in Dev Enviornment) with an instrument I communicated via RS232. Solution was to install the driver. As you supposed in your post.

Thank you for your help. It turned out to be the wiring of the cable.

The reason it worked in the test environment and not the actuall is a different ports were used. In the test environment a convertor from RS232 was used. The converter required a one wiring which was re-created for a RS485 card which required a different wiring.

Basically there was contention on the liine.
