  snap motor and hub overview
- a snap
motor is a completely integrated motor, gearhead,
encoder, amplifier and servo controller
- up to 6 motors plug into the snap hub using
standard CAT 5 cables
- the snap
hub can be programmed for stand-alone operation or used
in pass-thru mode
- use Windows software to write, download and debug embedded Motion Basic
programs
- snap motors can also be controlled directly from any computer using USB or
RS232
