Hi, My Electro-craft manual shows the command source to be a choice of +/-10v, Step/Direction, Master encoder input, 8 presets, or RS-232/485 commands.
It looks like you would need the windows based s/w for setup etc.
This allows you to configure, tune, set up I/O, Diagnostics etc.
The last I heard they were bought out by Rockwell Automation (Allen-Bradley).
