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
• Output pins 1,2,3,4,5,6,7,8,9,14,16,17. Or 1, 14,16,17.
• Input pins 10,11,12,13,15. Or 2,3,4,5,6,7,8,9,10,11,12,13,15.
• 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 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 ports
• 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 tested)

This breakout is very well put together. With socketed ICs is is very easy to recover from an oops. (Posted on 4/24/2015)

However, I wish at least 1 of the outputs pins could be jumper selectable to bypass the enable feature, so the charge pump signal from Mach3 could be transmitted to the screw terminals to connect to the Charge Pump and back to the enable feature. (we just cut the trace and bypassed it in hardware so pin 1 is always active and connected to our charge pump) (Posted on 10/14/2009)
