I tried the free trial a few months ago and I couldn't get it to work. I would like to make sure it works before I purchase anything.

Of course. Please do NOT buy it until you are sure it works.

If you email I will send another trial activation code.

Also, in your email, please describe the problem you had before. I mean did it show any errors on the computer or on the CNC?

Thank you for your email.

You have the USB plugged in but it looks as though your computer did NOT configure drivers for the Serial Device.

In the DNC Setup, in the upper right corner of the window, your version of easyDNC should display a list of serial ports in your computer. In your case the list is empty. No serial port exist.

A USB/Serial device is actually 2 devices in one. When you plug it in to the computer it will sometimes detect and configure the USB part of the device but fail to enable the Serial part of the device.

Go to the manufacturer's website (I sent a link by email) and download and install the device drivers. Once you've installed the device driver the serial port should should appear in that list so you can select it.

Hello Tim. Check your email. We replied to:- tim@relent****orts.com with your licence key.

In your email you mentioned that you'd purchased a USB-to-DB25. DO NOT connect that directly to the CNC.

Even though it may fit it's highly likely that you'll need an additional Cross-Over converter.

Assuming your USB/DB25 is a standard PC (or mac) connector and your CNC is something like a fanuc (many others have the same standard pin-outs as fanuc) then you'll need to make up a 'cross-over' cable between your USB/DB25 and the CNC. Like this:-

NOTE: This cable below is only for 25pin port at the computer end of the cable. If your computer has 9pin port see the diagram on the home page



If you're sure that your CNC uses XOnXoff flow control (or no flow control) then you can ignore the pins 4/5 between the PC and CNC. In that case just make a shorting link between pins 4 and 5 at the CNC end of the cable.

Notice that shorting link between pins 6, 8 and 20 at the CNC end of the cable. If that link is missing the CNC will likely throw a DTR/DR alarm and refuse to connect. That's why I said you'll need to "Make Up" the cable. Most shop-bought cables will not have that 6-8-20 link.
