Hello,
I am trying to find some information out about the Acorn ip address being
hardcoded. I want to buy the unit but it seems I will have to have 2 nic's
in my pc to access the 10.x.x.x network. Can I change the ip address of the
Acorn board to be on my network?
Thanks in advance,
Larry

The Acorn plugs directly into your NIC and it's IP address is updated/changed when you do the initial install. There is no "network", it's the Acorn and the CNCPC. You should use a DEDICATED PC for the Acorn. And not a laptop.

I understand that a dedicated pc should be used, the question is can the ip address, subnet mask and gateway of the Acorn be changed?

No.

Here's what I do. I use a NUK computer with my Taig mill. The NUK has both a RJ45 ethernet connector and a WiFi interface. I use the RJ45 ethernet connector for the Acorn and I use the WiFi connection ONLY when transferring a file from my personal network to the NUK. When I'm operating the Taig mill, I transfer a project file to the NUK's via the NUK's WiFi and then I disable the NUK's WiFi connection until I've finished running the project.

On my test bench, where I test another Acorn along with various experimental electronic devices, I have a desktop PC with two network cards. One card has a static IP address that matches the Acorn's network. The other ethernet card gets an IP address from the DHCP server on my personal network. Because that is a test bench where I only test the functionality of various parts and pieces, I leave both ethernet cards active all the time.

Years ago, I owned a Shopbot router. It was in my garage where I did not have a direct ethernet cable connection to my network. I installed a WiFi card in the Shopbot computer. The WiFi connection was not stable, so I finally installed an RJ45 jack for cabled ethernet service. Just after I had plugged in the ethernet RJ45 connection, a FedEx truck pulled up with a spindle from Shopbot. I installed the spindle. In the excitement of getting a spindle for the Shopbot, I completely forgot that I still had a WiFi card in the computer. The spindle was great, but I kept having unexplained crashes when Shopbot lost control. I spent over $750 on Input and Output fileters for the spindle. The filters didn't cure the problem. I fought the problem for well over a year, ruining job after job. Finally, late one night, I noticed a red indicator LED status symbol on the bottom of the computer screen at the same time that I heard the Shopbot crash. The red indicator LED status symbol was showing that the WiFi card was searching for a network. Duh! I removed the WiFi card and the Shopbot started working as expected. That is why I NEVER have WiFi activated when I'm running a job on any CNC machine.

Hey thanks this is what I'm looking for if there is no way to change the embedded ip for the Acorn.
