From memory, yes I think you can.

I haven't used one for a number of years and no longer have access to my code but I'm pretty sure I used two simultaneously. Looking at the velleman data sheet (here) it says it can be done and there is a 'card address' option in the test panel which gives you a two bit address (i.e. max four possible addresses for a card), so there are probably some jumpers on the board to set the address.

Hope that helps,

Ian

Hi

I found this on the HP of Velleman.eu

USB EXPERIMENT INTERFACE BOARD K8055

http://www.velleman.eu/distributor/products/view/?id=351346

here it says:

The number of inputs/outputs can be further expanded by connecting more (up to a maximum of four) cards to the PC's USB connectors.

if you scroll down you can find some interesting files and also a ready-to-use LabVIEW VI with K8055.dll

I hope this is usefull.

If not please let me know...

With Velleman's original firmware the maximum number ob boards is 4, but if you program PIC18F24J50 with your own code then you may connect as many boards as you like. This is what I did and it works perfectly. It even goves me a whole lot more functionalities like 10-bit A/D converions and up to 12 extenal analog channels...

Try to type in "K8055 pc usb projects" into Google and you will find a number of ides to do much more with K8055 or K8055N experiment board than you have ever thought of.
