KB946: What does the "DCC symbol" mean?

Companies that sell interoperable equipment compatible with the NMRA's DCC "Standard" often use the DCC logo to let customers know that they support basic DCC standardization by producing DCC compatible equipment.

This symbol is seen on many DCC compatible products because the NMRA DCC "Standards and RP's" do not cover all DCC compatible equipment and therefore not all DCC compatible equipment is eligible for a conformance seal. Basically, command stations and decoders are covered by the "Standards and RP's". Throttles (or cabs), computer interfaces, boosters (or power stations), computer based programmers, cab buses, control buses, control networks, radio and infrared interfaces, block detection devices and signaling devices are not covered by NMRA "Standards or RPs".

THIS SYMBOL IS NOT A CONFORMANCE SEAL AND IS NOT AN ENDORSEMENT BY THE NMRA!
