Sounds like some nice improvements to an already good product.
Larry - any chance of you putting some command line controls to the Servo Motors - to test the Viper card to the servo motor directly from the Viper?
This might make the Control card parameter set up easier than going into the Viper, set the settings, save the settings, then getting out to the controller software (in my case Mach3), running some code or MDI then back into the larken, etc...
