C10
- BIDIRECTIONAL BREAKOUT BOARD Rev.
8
Overview.
This card provides an easy way of
interfacing your inputs and outputs from you
parallel port. It provides terminals for the
connections and conditions the signals for use
in CNC applications.
Features
Buffered inputs and
outputs. Outputs are buffered through
integrated circuits, allowing the card to output
the signals without using the power from the
parallel port. It can take the +3.3 or +5vdc at
10 milliamps from the parallel port and deliver
solid +5vdc at 24 milliamps.
Has the
option of using pins (2-9) for input or output.
By selecting the appropriate jumper
setting you can use pins these for input or
output. If you use a second parallel port and
set it to work in a bidirectional way, you get a
total of 34 I/O pins.

Input and output pins with
close by ground or +5vdc
connections.
The common terminal to pins
2-9 can be ground or +5vdc. The board
has a jumper that allows you to select if the
common terminal to pins 2-9 will carry a ground
or +5vdc. So if you are connecting encoders or
proximity switches, you can select it to ground.
If you are connecting Geckodrives or limit
switches, you can set it to be +5vdc.
External Enable Pin (EN).
The board has a pin that allows you
enable/disable all the outputs at once. The
board requires +5vdc in the EN pin. If it is not
present, it will send all the outputs to ground
immediately. You can use this enable and disable
your system manually, or you can install an
external Safety Charge Pump or other external
device.
All TTL +5VDC or +3.3VDC
Signals. Works with newer computers and
laptops that have low voltage parallel ports
All inputs are outputs are
tied to pull-down resistors. Pins are
never in the air open to noise. If you leave a
pin in the air you will get a LOW or 0. If you
input a ground you will get a LOW and a +3.3 or+
5 vdc signal will deliver a HI.
Works directly with popular
CNC hardware and software. Such as
Geckodrive, DeskCNC or Rutex, and parallel port
control software, such as mach2, Linux EMC,
TurboCNC, CNCPlayer, CNCZeus and others. (Not
all tested)
