I need help on design of a low speed (2 sample/sec for each ch),16bit,isolated ,universal analog input ,serial output port with networking capability for industerial monitoring systems.
(inputs: mA/mv/V,THC,RTD(3,4 wire))
I hope this useful to you, please below XEMICS web.
You may can find informations and devices.

Search in google for 8255 cards. You can use interrupt when adc process completed. I think it's more useful. You should use portA and portB for 16 bit data acquistion and portC for addressing for adc's.
