SPECIFICATIONS Power Requirements It requires a 5VDC @ 500 milliamps power supply to operate. This power can be taken from the computer’s power supply or USB port. Consider using the A3 – USB Power Cable found under Accessories in the website. WARNING Check the polarity and voltage of the external power source and connect the 5VDC and GND. -

Page 7: Especial Functions
ESPECIAL FUNCTIONS Safety Charge Pump "SCP". (Pin 17) This board takes advantage of Mach ability to send a specific frequency through one of the pins of the parallel port when the program is in control of the system. CNC machinery can be very dangerous, and you could have a risk of the machine doing something different that what you intend the machine to do if the program loses control of your system. -
Page 8: Enable Pin
Selecting the SCHP operation mode The Safety Charge Pump can be activated or deactivated depending on the jumper position. 1-2: ON 2-3: OFF Note: When the Safety Charge Pump is activated, the EN terminal is active and a valid SCHP signal is present, pin 17 will go high. This high signal can be used to enable other external devices, such as enabling other Breakout Boards, or relays that would enable servos, VFDs, contactors, etc. -

Connecting NPN open collector proximity sensor with the C35S R1 Value (12V) R1 Value (24V) Approx. - Page 13 Some NPN proximity sensor has a pull-up resistor (R1) internally. It is necessary to know its value in order to connect safely the sensor with the BOB. Follow this recommendation: Connecting NPN open collector proximity sensor with the C35S (R1+R2) Value (12V) (R1+R2) Value (24V) Approx.
