Actionner relais

[nathand]

Did you note that the poster wants to use a 1902, not a 9102? And if you look at the manual for the 1902, the "remote control" is just driving two analog channels, which should be fine with an NI-9264. No special driver necessary. This does seem overly complicated just to turn a relay on and off, though.

Hi Nathan,

yes I know how to read thank you. what was not clear in "Try to create or use the existing drivers, most of the time only command change  :"?

It was just pure coincidence the selection was on 9102 in the list. I just wanted to point out that he could base the creation of its own driver/ bundle of functions to communicate with the 1902 on the already available drivers from the same vendor..

Indeed most of the time, drivers for the same type of instruments and from the same vendor follow the same design and just few VIs are not compatible.

Thank for making me repeat  as it was not clear enough apparently.

You might want to read the manual for the device the poster wants to use. It doesn't have a serial interface. It accepts no commands. There's no way to reuse an existing serial driver. The remote interface is just 2 analog channels and one digital signal.
