There is a description on the Langmuir product page that shows how to tell if the CrossFire is original (and uses Mach3) or a newer one. You would have to search the site, but it’s off of the CrossFire upgrade pages.
Thank you for pointing me in the right direction I found the info
Under “Support” “Should i use Firecontrol
There is a picrure showing the 2 different comtrol boxes…a quick telltale is Mach3 has green around the USB port Firecontrol is Red
