Does anyone have details on the signals used in
the (old) Dataproducts printer inteface? Basically
I know it uses differential signals - otherwise similar
to centronics - but I would like details.
I have the Pinout:
http://www.hardwarebook.net/connector/parallel/dataproductsdsub50.html
I would like a description of "Demand" signal
and the polarity of "Strobe" and "OnLine"
I would like to know the levels (I presume TTL)
If anyone can help me out, perhaps I can respond
in kind by giving them the final result - a circuit
for a Centronics-->Dataproducts interface.
