RailCon DCC Control System

 

The RailCon DCC control is a modular system that provides control for a wide range of accessories from your DCC control handset or from a computer running layout control software. The use of the modular concept in the RailCon DCC control system separates the process of decoding from the process of activating an accessory. This provides greater flexibility in how accessories are used in your model railway layout and allows different types of accessory to be controlled from a single central control unit.

For example, on your layout you may have a yard area that has a turntable, points, signals and lighting. These may all be controlled via one central control unit with the appropriate slave modules connected as shown in the following diagram.

Operating Principle

During operation of the system, accessory decoder commands are sent from the DCC command station via the track. The central control unit is connected to the track and receives accessory decoder commands, in the form of data packets, sent from the DCC command station. On receipt of a data packet, the central control unit decodes the data contained in the packet and checks if the address contained in the packet matches any of the addresses programmed into the central control unit. If an address match is found the data in the accessory decoder command is decoded and the required action is carried out on the addressed accessory.

The block diagram below shows an example of how the RailCon system may be configured. As depicted in the diagram, the operator uses his hand controller to initiate a request for an accessory action. This request goes to the command station via the control bus where a DCC accessory decoder command is generated and sent as a data packet via the track.

The RailCon central control unit is connected to the track and continually monitors the data packets sent from the DCC command station. When an accessory decoder command is found, the central control unit checks if the command is addressed to and, if it is, the data packet is decoded and the required accessory is activated.
