hi jeorg
if i understand correctly you have to test every unit that comes out
of the factory with tests according to the iec601 ?
one thing about irda versus cable -
we can use a very simple not irda - infrared comm , that we'll
specially design with full duplex , 115000 baud , and because we have
to build reciever card - we can build it to connect to printer port
throught long 5meter cable . this could be very simple little card ,
that can be put near the device , and he'll get he's power from
the printer port .
i think this interface design could be very simple one .
it's seems o.k. with you ?
thanks yaniv v
