Vizard how to send information through DA card in realtime

[gachful]

Hi Jeff,
We are from a neuroscience lab doing some experements on some low level primates, and what we need to do now is send the Location data (x,y) and head direction data to another computer from Vizard in real times. But we can't use Ethernet to do this due to our setups.
We consider to use a Digital-Analog Card(DA card) in Vizard computer, and send the datas as analog signals. But we really don’t know how to do this.The basic question is whether vizard support some specific DA card? And how to use python to control a DA card.
We have connected with NI company(they sells some card like this), but they said they don’t use python as a languish.
