Parallel Port Break-out Board (PP-BOB*-v2)

1. All buffered outputs are taken out to screw terminals.
2. All the s are optoisolated,filtered and buffered for noise immunity.
3. All s or outputs like estop, chargepump, relays can be reclaimed and used for any purpose with jumpers.
4. On board rectifier and filter, accepts 9V to *5V AC or DC for power.
5. On s, both terminals of optoisolator are connected to screw terminals, providing flexible connection to source / sink type s and with external series resistor can tke from 5V to *4V s.
6. *6 pins FRC as well as DB *5 connectors.
7. An on board charge pumo for safety is provided.
8. For enabling the hardware slavage of 2 motors on one axis for gantary style machines; one axis outputs i.e. step and dir are buffered twice and taken out control box to terminals.
9. For spindle and auxillary on-off control, an on board relay is given improve flexibility further.
*0. Hand made high quality, low resistance, shielded male-to-male parallel port cable included.
*1. LED indicators provided - Power OK, Estop OK, Relay ON and Chargepump OK signals.
*2. Made in India

Enhanched Parallel Port Break-out Board (PP-BOB*-v1):

1. All the s are opto-isolated,filtered and buffered for noise immunity.
2. All the outputs are buffered and taken out to screw terminals.
3. Selection of pull up or pull-down for motor outputs.
4. All outputs and s have LED indicators for easy diagnostics.
5. Motor output common terminal can be selected as 0V or 5V.
