The one in the video is an arduino leonado emulating a keyboard thus connected by usb, this was purely to show that the keyboard plugin can be used if required. And they do a Ethernet version.
At the moment I am designing a shield that connects to the ESS and uses the input and output signals and uses a mega chip to run the 4D screen and external functions, this wont be used for jogging as the screen will be mounted in the case, but could be used for homing and moving to preset points etc. All signals will then be sent and recieved through the ESS, and as something comes up that is required I dont have to wait for someone else to implement it. I have been testing out with great success in the PLC script a form off sending out a series of output signals and the mega displaying something (er a bit like binary if you like). will keep you posted on that.
Yes the keyboard plugin does have its drawbacks, only this morning mach4 was in the background whilst I came to have a look at this board (did you and daniellyall stay up all night??) and went to reply to a thread, DAM!!! the 4 keys were still assigned to jogging from yesterday and the machine started moveing, but has been tested using the signal inputs not keyboard with success, they must use internal mach4 functions.
Although even that dont put me off the keyboard principle, its all down to what you can achieve in the PLC script, IE most things are safer to run in the PLC a simple function, if wxlua screen lost focus then dissable keyboard plugin etc.
