Build a USB powered 12bit adc and 24bit dio card

[DAQCHINA]

To buid a USB powered adc and dio card under master mode is just as simple as control a standard printer port or ISA dio card. For circuit and full document, see http://www.daqchina.net/daqchina/acquire/daq24l08.htm

To buid up a USB dio adapter, see http://www.daqchina.net/daqchina/acquire/usbdioe.pdf

To get an inexpensive and multiplat form adaptable Quadrature encoder module, see http://www.daqchina.net/q502a.htm

What we need is a 24 bit ADC and a 12 Bit IO card ;-)...Got one?

What difference with ADC and DIO ?

To design PCBs, ADC and DIO use different ICs but the base board is nearly the same. www.daqchina.net gives many schematics free but it is now closed. I tried to contact but in vain, and actually, it seems that they never sell cards or chips. It is free for hobbies and no sell I believe. You may find their reference board for design but not for sell in a store or so.

Sometimes the link opens with a Welcome page written in Chinese, but other times it says "Forbidden - you don't have permission to access / on this server.
Basically, the Chinese page says that you are trying to access a link that doesn't exist, and the page cannot be opened. A list of possible causes are then listed.
So it seems the page has been removed.
