PP-BOB3-v1 has all the features of PP-BOB2 but has differential outputs for direct connection to servo drivers, 2 inputs in this board have high speed opto-coupler for connecting encoder input. Supplied with 1 meter high quality DB25 parallel port cable. Also has isolated PWM to 0-10v convertor output that is used for connection to Variable frequency drive for spindle speed control. Comes with built-in charge pump that keeps outputs disabled in the absence of charge pump signal. All inputs are opto-isolated and filtered for noise. PP-BOB2-v2 works with Mach3, LinuxCNC etc, it has 4 axis (5 motors) single ended outputs with one motor out buffered twice and brought to connector for easy connection of 2 motors for gantry style CNC machines.
