  • DCC QUESTIONS [REPOSTED]

    1. WHAT IS A DECODER HEADER?

    2. Is it unwise to wish to put a decoder socket in every loco? The sole reason for this, is to allow plug-and-run with an upgraded decoder at any time, without need to solder, resolder wiring. Space MUST be the deciding factor here...Tom.

    It can't hurt and it makes it very ready for DCC so I would have to give a strong no to your question.

      I wish every Manufacturer did put a DCC socket in every Loco. But many of mine are older than DCC.

        According to Khutch, who really knows his stuff and is a member of the Atlas forum, "A header is another term for half of an electrical connector. It is usually the part that is soldered to a circuit board (a decoder for instance) and mates with a connector that is usually part of a wiring harness."

          Hi, Tom. A header is the wiring harness part of a decoder (usually HO size or larger) which has a set of miniature female sockets in a single row. This header is usually permanently wired into the loco so the decoder (which has the matching male pins mounted on one end) can be plugged into it and conveniently unplugged and moved to another loco or replaced in case of service or upgrade. Following the header route, you could permanently wire several locos with headers and share a single decoder among them. This idea was more practical in the early days of dcc when decoders were more expensive in relation to the cost of locos than they are today. Now that decoders are rather inexpensive, it becomes almost economically impractical to install headers in locos because the harness/header usually costs almost as much as two function decoders do in volume. Also, more locos now come with the NMRA 8 pin mini socket in them, negating the need for hardwiring in a header.

          As for whether it's wise or not to install either a header or an NMRA socket in every loco, you're right - space and money are the deciding factors.

          Lou.

            The small socket defined in RP 9.1.1, which I believe is usually used for N scale, when mounted in the locomotive, almost fits this description. Other than not being HO, is it considered a header?
