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. Mach can be programmed in a way, so when it is “in control”, it delivers a 12.5 KHz signal through one of the pins. This card lets you use this signal to work as an On/Off switch for your system, enabling a powerful safety system for your equipment.
FEATURES:
Takes advantage of the 12.5 KHz signal from Mach. When Mach X is in control it can emit a 12.5 KHz signal that can be used as an On-Off safety switch for your system.
Microcontroller based system. New since revision 5 of this board. They now come with a microcontroller that allows the implementation of more complex algorithms for sampling and analyzing the signal.
TTL compatible. 5V and 3.3V signal can be connected to the pulse input.
You can use it to control your Parallel Port Interface Card or any other device that can control your system. This device acts as an On/Off switch for your system. When hooked up, you can control what is powered or not.
