A little late on the follow-up, but I ended up having to pull the VME 4000 out and returning the next day to re-install. It was integrating with an old Samsung DCS 50si. The Samsung adjustments worked just fine and there were no issues with the Samsung sending commands to the VM, but the VM wasn't sending the proper codes back to the Samsung.
I did try ITS Telecom's website and I googled from one end of the internet to another. Since we ordered it from them directly online, we had no local distributor to contact. I did receive an email from ITS (at 1:32 AM my time) telling me to contact my distributor and after one more email exchange was connected with someone in St. Louis.
With the distributor's assistance, we were able to get the integration to work... mostly by adding pauses in the transaction codes from the VME end.
Whew... it only took 2 days and 8 man hours more than it should have.
