-I worked in many systems using rs422 srial interfaced modules, and

-about parallel? Were did you found it?

Most Line Scan and digital o/p cameras either come as TTL levels or RS422 (some
both), hence most framegrabbers that have digital capability have RS422 
capability as this is the preferred method for machine vision to remove most of 
the electrical pickup in transmission. Factories and the like are very hostile 
environments for noise, whilst RS422 can drive longer distances as well.

For Frame grabbers ask for Digital Input devices

Try	Imaging Technology
	Matrox
	DataCube
	Mutech
	Synoptics
	Most major players

For DSP based acquisition using i860 try Alacron

Their are probably more around but those are the first ones that come to mind!
