I have the proxies assigned to software encoders and i have each software encoder linked to joint index enable and encoder index enable as per the help file... It shouldn't really care if it's an encoder or a prox for the index pulse, it's just looking for a signal.
I'll send a snip of my hal file. I just turned my machine back on Phil T.
