I have one CM20 and just added another the other day. The new one does not work with my layouts walkaround capabilities. The old pack works just fine with the same set-up. Essentially, I have no control of the trains and the direction switches whenever I change the location of the walkaround throttle. I know I have more phone cord than recommended, at about 75 feet, but the other CM20 works just fine. Anyone else experience trouble like this? Are the new packs just not as good electronically as the old? Is the pack defective? Any suggestions would be appreciated.
I have had a simular experience with my CM20,s They would run wide open with no direction control. The problem was a burned out transister,
the last cm 20 you purchased is what they call version two. It will probably say that on the back of the handheld. This handheld is not compatible with the older cm 20 and vice -versa for the old working with the new. Each has to have its own set of jacks around the layout or plugged directly into it’s own unit. In other words each handheld will work properly only with the unit that it originally came with. Why they did that I don’t know. Hope this helps.
Nice of them to advertise it. Isn’t that what they call bait and switch? Always buy way more than you need when buying anything elctronic these days. just look at computers.
What you bought today is out-of-date tommorrow! Ask all those DCC guys. Anyone with a brain buys decoders in bulk! Nxt week they’ll be out of date.
? without exception all the DCC companies are small, in my experience products tend to hang around rather a long time. Development is not moving so rapidly that decoders are obsolete in a year, let alone a week. This is not the cell phone business where a new model has a shelf life of 6 months at most. What you are talking about here is compatibility. Many companies, though not all, go out of their way to ensure backwards compatibility between generations of product. A 10 year old decoder may not have the features you want, but you can still run it on a modern DCC layout.
The company in question here, MRC, is notorious within the DCC community for introducing new generation DCC equipment that is not compatible with their older DCC product. This is not the case with many of the other manufacturers.
Is the HO/G scale switch set to HO? If so,then I suggest contacting MRC.
