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
• 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 less than
1 milliamp from the parallel port and deliver solid +5vdc at 24
• IEEE 1284 Standard compatible.
Includes the circuitry recommended by the IEEE 1284 Level 1
standards for bidirectional parallel communications between
personal computers and peripherals.
• Has the option of using pins (2-9) for input
or output. By selecting the appropriate jumper setting you
can use these pins 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.
• Output pins
1,2,3,4,5,6,7,8,9,14,16,17. Or 1,
• Input pins 10,11,12,13,15. Or
• 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
• External Enable Pin (EN). The board
has a pin that allows you to 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. You can use this to enable
or disable the 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
• PULL-UP or PULL-DOWN selection for
inputs. Includes jumpers to select the best input
configuration for your application.
• 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
