How many of us on the forum had their HD621 installed? Now you may say that the majority of people on here would like to try themselves. I would be curious to see how many dealers "offer" to spend a few hours out of sales to install the unit. Perhaps many, but my hunch says that the majority of HD621 units sold were not installed by a dealer.
Therefor all I am saying is, consumers should be given the tools to correctly integrate their new product with the BEST experience possible.
Agreed, consumers should be given easily accessible support and tools. Unfortunately, Mconfig and the required RS-232 cable don't facilitate that.
As for the HD621, there are numerous lengthly threads trying to get HH HD621 users over significant issues configuring their 621s. As simple as the HD621 device is, it isn't seamless and installation can be complicated for the most knowledgeable users.
