I have a project where I need 4 analog outputs in the same time. Is it possible to use two VM110 cards?

{from another forum user, not on behalf of Velleman.}
The K8055/VM110 card has an ‘address’ which is set by the 2 jumpers SK5/6. That address has to match the argument given to the ‘OpenDevice’ command that sets up communication with the card.
So, YES, in theory you can use up to 4 such cards at once. (I’ve never used more than one.)
Or you could use the K8061 card which features a lot of input and outputs.
At this time, only available as a kit, but assembled version will soon be available.
I know that i can use up to 4 card’s but i can’t make two of them work simultaneously (in the same time in one program) i need to reinitialize the address… because when i try to use them both in the same program only the last initialized works.
so maybe I’m missing something or making wrong 
and the other card looks nice but i already have two of those and i need only 4 analog output’s…
if anybody has any ideas i would really appreciate it.

That looks like the documented behaviour of the OpenDevice call:
“This function can ALSO be used to select the active K8055 card to read and write the data. All the communication routines after this function call are addressed to this card until the other card is selected by this function call.”
Have you looked at the documentation for the updated DLL?
There is now a FindDevices routine, and a SetCurrentDevice routine - I think these are meant to make a multicard environment easier.

Thanks I’ll try it and post what came out.
