. . . I never did find out what was so special about it. I'm thinking maybe it is some sort of pseudo active termination? ties back the 5v line to pretend to be active termination maybe?

I'm hoping someone can post up the schematic for that beast if they have it. I would certainly love to find out what the deal is with that black termination block.

IIRC, there's no schematic and no active termination, it just has resistor packs that're "stronger" than the "standard' terminator's spec.

Dunno what the value is offhand, but I've got GttMFH: Second Edition, so i can look it up later. Try checking the DevNotes, you'll probably find the answer faster, i can't post it until tomorrow, IF i remember to look!

You might also try googling for the resistance differential. [] ]'>
