Hi Dave,

Here is the best we can offer. We know the mtr2000 are touchy and hard to get just right. We don’t have any personal experience with them but lots of effort went into getting our mtr controller board tested by a couple brave souls. The two gentlemen that pulled this information together took about 3 months going back and forth in the end to get it working properly.
