KB477: PM42 - Third Party DCC Command Systems

This article was last updated on Sept. 3, 2011, 4:31 p.m. | Print Article | Leave Feedback


Q:  Can I use a PM42 with a non-Digitrax DCC Command system?

A:  The PM42 was specifically designed to work with Digitrax Direct Home wired layouts. Any system that is configured this way will probably work with the PM42 with no interoperability issues. Digitrax has no control over or knowledge of each specific non-Digitrax system and how it may interact with the PM42.

The PM42 can be used as a stand-alone auto-reversing unit and short circuit manager with many third party DCC systems, but for systems without LocoNet capability a number of the networked management features will not be available.

A Digitrax command station is not needed to access the Option Switches. A Digitrax DT-series throttle or a PC equipped with an MS100, or equivalent device, and appropriate software can also be used to access the PM42 Option Switches.

Exercise care when combining components from different control systems, especially with their ground return or common legs. Be sure that the LocoNet common ground return is not energized with rail voltage if it is going to be used with other equipment.
