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

Ah, I think I see where our thoughts are not quite joined up - I'm talking (and I'm interpreting Ian's intent here) - of connecting the UCx00 to the 25 pin D-Sub connector on the control box, using the internal System 4C components that implement the BoB and the Driver electronics. NOT, taking the UCx00 device to connect direct to the drivers.

Doddy, you have interpreted my intent correctly
So connection wise I think I'd only need a D-sub 25 pin connector to solder on to one end of my lpt cable.

I'm hoping you were meaning the main board 12V (12-24) supply for the UCx00 when you mentioned 5V.
I had realised the 12V board supply isn't rated highly enough for the UCx00, which is a pity.

Back in 2012 I did post on here a few times while I was trying to sort out the earthing faults, but it looks like that is a time that has been lost to internet history!

A_camera, sorry I didn't explain things more clearly . If I can manage it, I'll post the manual and assembly pdfs....
Here we go, at least they are on the site if anyone needs them..
