DCC Programming

The Digikeijs DR4018 accessory decoders are a great unit for controlling your points and signals. The basic factory configuration is set up to use all 16 outputs in pairs, to control a maximum of 8 points. Programming the unit to control any combination of points, simple on/off loads, SEEP motors and LED signals is easy using our online CVV calculator. Simply select the desired things you want to control, in the order you want them in, and our calculator will generate the CVV values you need to program your DR4018 with.
