Re: [CAD_CAM_EDM_DRO] house connector block & DB25

Peter,

Here's what I did when I was looking at different controllers.
Went to Radio Shack and bought a little jumper box. It's got
a DB25 on each end and is a little larger than a match box.
They call it a RS232 jumper box, but a DB25 is a DB25.
Anyway, you can wire one up for each controller you use.
When you switch controllers, just switch the jumper box.

Here is a link to Radio Shack that shows it.

If the link does not work do a search for "Jumper" and look at
