Serial port inputs and outputs
« on: November 04, 2006, 05:56:52 PM »
I was needing some more inputs and outputs for my mill than one DB25 can handle. Thus I was wondering if Mach3 had any support for serial port. Specifically I was thinking about designing and building a USB adapter, which looks like serial port, that would allow me to have additional IO ports. Is there support in Mach 3 for this aready? If so is there documentation?

Thanks

Hey Trampas
In config, ports and pins you can set up more ports. :) I don't know about the docs., sure there is though.

You could fit a second parallel port or a ModIO

With modio you get 8 inputs and 8 outputs + 3 analogue

Hi, You might be interested in a macro I have posted in the downloads section of the forum which uses the serial port to communicate with a microcontroller to operate a toolchanger.



Cheers

Thanks!

I was thinking about making a device which has about 16 inputs and outputs as well as some jog knobs and PWM stepper drivers. I was debating on adding some LCDs for DRO, but with Mach3 this may not be useful. The main thing I wanted was to have enough inputs and outputs such that I connect all my limit switches and encoders. I did not want to use another parrallel port as that a lot of computers do not come with parrallel ports, thus USB seemed much more logical.

Here are a couple of links. The IPac 4 is a keystroke emulator that has, I think 56 inputs. This works good for buttons and switches. It is a snap to set up in keygrabber.
