C11 (Rev. 8) User Manual
C11- MULTIFUNCTION CNC BOARD Rev. 8
1. Overview
This card has been designed to provide a flexible interface and functions to your
computer projects, by using the parallel port control software. This board provides
a faster way to connect devices and reduce the possibility of wiring errors.
2. Features
• Fully optosiolated
The card isolates connections to
protect your computer from short-
circuit.
An
opto-isolator
integrated circuit that transmits the
signal through an encapsulated LED
and phototransistor. When the signal
is
on,
the
LED
phototransistor captures it and relays
the signal. The signals are transmitted
through light and not through physical
connections. In this way, a power
surge has no way of reaching your
computer. That is the reason why this
card has two power connections. One

power connection is power powering
the circuit that interacts with the PC,
the other connection is for powering
the circuit that interacts with your
CNC system. Extra precautions have
been taken when designing this
circuit, by taking into consideration
the extremely high voltages that
stepper drivers can achieve and lack
of experience that some users could
have in wiring circuits of this kind.
This board keeps the grounds of the
PC isolated from the grounds of the
rest of your CNC circuit.
