Do I need a BoB when replacing a parallel port connection with a UC300 or UC400?

I see. Thanks for clearing the confusion. Yes, that's easy to do. You just plug in the UC400 to the DB25 on the box. No need of soldering because there is a ready made ribbon cable which is delivered with the UC400, which is the obvious choice for you. Just connect that to a small psu and to the LAN and off you go. It should work immediately once you have configured it. Will you be using UCCNC as well? I think it would be the best and maybe CNCDrive has some special deal when you buy both. I got my license almost for free when I bought my UC300ETH some years ago.

Well I've spent some money...
Dean only stocks the UC300ETH and AXBB so I've ordered a UC400ETH direct from CNCDrive.
We'll see how buying from Europe works these days...
I'm expecting to have to pay the VAT when it gets over here. I think I should save about £25 compared to buying from CNC4YOU.
I didn't order the UCCNC software cos I was chugging along OK with Mach 3.
I'll let you know how it goes.....
