Digital Command Control. Digital Command Control (DCC) is a standard for a system for the digital operation of model railways that permits locomotives on the same electrical section of track to be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA).

The story of DCC must start with analogue control, or direct DC, whereby an electric model locomotive is controlled by applying a variable direct current through the track; direction is changed by changing current polarity and speed by varying the voltage. This is the system most familiar to modellers and has been used at every level from the train...
With Digital Command Control (DCC) you use a controller (also called cabs or throttles) to send information to a command station telling it what you want train X to do. The command station then takes this information, transforms it into a stream of digital code and sends it to the booster. The booster will add power to the code, and broadcast the c...
Operation is far more exciting with each train running independently. You can use double heading or banking and match the speeds of locomotives from different manufacturers. You can program realistic acceleration and deceleration rates, or limit the top speed of a locomotive. DCC has advantages for everyone from the beginner to the advanced modelle...
Although DCC offers great advances in control it is not a cure-all for old problems and brings one new problem. If an item functions poorly using DC just adding DCC will not cure it. Remember: 1. A short circuit is still a short circuit. Although wiring is much simplified it must still be done properly and bear in mind the higher current ratings th...
DCC systems are sophisticated manual controllers. They use computer based technology but do not, by themselves, automate your railway. Automatic train movements and shuttles can be achieved but require much additional hardware and software to do so.
The Data Communications Company (DCC) Part of Capita PLC, the DCC is a monopoly company that operates under the Smart Meter Communications Licence, which is regulated by Ofgem. It is responsible for linking smart meters in homes and small businesses with energy suppliers, network operators and energy service companies.
Aug 29, 2023 · SMETS2 is the current and most advanced standard for smart meters in the UK. These meters offer improved interoperability, ensuring that their smart features remain active regardless of the energy supplier. SMETS2 meters use a consistent communication protocol called the Data Communications Company (DCC) network. This network connects all smart ...
The role of the DCC. Since being awarded the Smart Meter Communication Licence in 2013, the DCC has designed, built, and now manages the telecommunications technology infrastructure that underpins the smart meter roll-out. At scale, the smart metering system will support secure data communication across 100 million devices in 30 million ...
Dec 10, 2020 · Digital Command Control, commonly known by the acronym "DCC," refers to the Digital Command Control Standard created by the National Model Railroad Association (NMRA). DCC revolutionized train control by allowing for multiple locomotives to operate independently on a layout. DCC control is accomplished in two ways on a layout. First, the layout ...

May 4, 2024 · Rather than re-invent the wheel, the DCC Working Group studied all of the commercially available command control systems. Proposals were received from Keller and Marklin. The Working Group found that the best system to base the new standard on was a system invented by Lenz Elektronik, which was used at that time by Marklin for their 2-rail sets.
