You don't connect the computer to the track, you'd connect it to either an interface to your DCC system or a stand-alone programmer. If your MRC 2000 doesn't have a computer interface, you have a couple other options.
One option, of course, would be to buy a DCC system that *does* have an computer interface available.
Another would be to buy a stand-alone programmer such as the Sprog or the Digitrax PR3 Xtra. For CV programming, neither of those depend on connecting to an actual DCC system (Well, the Sprog "kind of" does , it actually *is* a self-contained DCC system).
There's also the BLI "Address Changer", but as it's name implies it's limited to changing addresses, and I believe it costs the same or more than either of the other two stand-alone programmers listed above (which can change any/all CV's).
Yes, the MRC2K does not have a computer interface. I use to have one. Liked five throttles and could run on DC only loco with a siding to shut it down.
I sold it and bought a NCE Power Cab. It does not run a DC loco though.
There are some programmers on the market as was mentioned.
Google dcc cv programmer. I just did. There is a lot of info out there. You can find reviews from those who have used them. Most probably you will find You Tube videos of people using them.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
OK, then! I check them out. Thanks for the help!
I would go with Steve's first option: Buy a DCC system where you can access your CVs in either programming track or programming on the main (POM) modes. You don't need JMRI to do that. It's just a handy interface for viewing/reading/programming more than one CV at a time.

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
If you want the Power Cab, go to the NCE website. The manuals are there. The Power Cab can also work with JMRI. If you eventually get quite a few DCC locos, JMRI is handy for keeping track of all the CV's.
Actually all DCC manufacturers have their manuals online as far as I know.
