1. You dont have to set up the address in ports and pins for the ports, the plugin does away with the need for that, having an address in wont do any harm. As for what to put in as a port in your I/O etc its just 1, 2 or 3 like you suspected.
2. Chargepump is not required as the SS loads the plugin each time Mach starts so no commands can happen unless Mach is in control. If the SS loses communication its buffer runs dry and then no more motion will happen.
3. Backlash is still not done but softlimits and threading(lathe) are fine, in fact threading is excellent with the SS
4. If your enceder is differential it will have A+, A-, B+, B- . Differential encoders are much less prone to noise. You can get single ended to differential adapters, they are not that expensive from US Digital but you may not need them if the cable is properly shielded and fairly short.
