Good stuff!
I have used them years without problems (knock knock:). Extremely easy to program with their Vee lib (makes it's own menu to Vee developer UI). Remember to order that too (not free).

Subject: [vrf] Digital IO using VEE
> Hi all,

Are there any Digital IO cards that software controllable
through VEE out there? I know National Instruments makes them but I am
trying to stay away from LabView.
I need to do the following cheap and efficient.
I know it can be done with VEE and a logic analyzer or pattern
generator, but that is expensive.
1. Send out a total of 11 bits of parallel data (TTL).
(This I can do with hardware I currently have, which is a
HP34970A, and a HP34903A 20-Channel General Switch. (Pull-up to 5V or
down to ground.)
2. 48 bits of serial data at a 1Mb/s rate, every 20mS.
I know step 1 can be down in Visual Basic or C to program the
parallel port, but I would like to keep it all in VEE since I am also
controlling GPIB Equipment after the commands are sent out. Also the PC
serial port is not fast enough for step 2.
Again I know NI has plenty of Digital IO cards out there that
will do this, but has anyone tackled something like this in VEE.
I would appreciate any suggestions.
Thanks
Damian.
