Serial Communication with COMPUMOTOR

[Gros SeB]

I have a COMPUMOTOR and I'm able to communicate with it through Hyperterminal. But I haven't succeed in communicating using Labview through the example serial com VI's. Does anybody know what is the termination needed in the message (CR , NL) ?

Hi Gros SeB,

I checked with some computmotor documentation, and a Carriage Return should be the right termination character.

Make sure you are actually sending in the ASCII representation of CR. You may want to set your textbox to be in HEX mode to be sure. But the easiest way to do this is to concatenate a carriage return string constant from LabVIEW, to your command.

Hope this helps.

Hi there!

I've got a Compumotor S series and I would like to quick test it using labview. The problem is that I have no idea how to do that. Can you give some help.

Thanks in advance
