Basically, the MACH3 USB Martzis USB HID Interface (MUHI) Board is a generic Human Interface Device (HID) so most operating systems support it, including Windows and Linux. Although, The card was primarily developed to be used with LinuxCNC software, there is a plugin wich makes the card Mach 3 compatible. Furthermore, the card works also with Mach 3 keygrabber without encoder support. Please check this video.
MACH3 USB Martzis USB HID Interface (MUHI) Board Inputs
- 64 digital inputs (LS TTL)
- 4 analog inputs (0-5V)
- 4 encoder inputs (1x or 2x)
- All 64 digital 5V logic inputs are pulled up via LS TTL internal resistors. You can connect a simple switch can directly between input and ground.
- 4 analog inputs can measure a voltage between 0-5V. You can connect a potentiometer directly to these inputs. Connect the center wire to the input pin and two other wires to ground and 5V connectors.
