VM110 and more than 4 boards on one PC

Hi.

I have successfully created an ap that will monitor door opeinings, however I want to monitor 36 of them from one PC. I know that up to 4 of the VM110’s can be used together giving me 20 digital inputs. Is there another product or way that I can scale upto 32 / 36.

Thanks in advance

Regards

Terry

DOH! - I just looked on your website and the the VM140 looks about right. Is it the same coding standards as the 110?

Thanks
