Digital operation in Motorola II format: maximum of 255 addresses, 14 or 27 speed steps, functions F0 to F8 (F5 to F8 via second address). Programming: register. Digital operation in DCC format: 127 basic addresses or 10,239 extended addresses, 14, 28, or 128 speed steps, functions F0 to F28. Programming: configuration variables (Direct Programming on the programming track, DCC compliant) or POM (Programming on Main = main track programming). Analog operation: analog systems with DC or AC power supply. Automatic analog detection, which can be disabled. Adaptation to various motor types and locomotive types: adjustment of load regulation parameters (KP, KI, KD), gain factor. Definition of a linear (possibly kinked) speed characteristic curve by setting the start, mid, and maximum speed. In 27/28 speed step mode: individual assignment of a motor voltage to each speed step. Start kick, shunting gear, reduction of the speed of all speed steps by approximately 50%. Switching to shunting gear with a function key. Start and brake delay: adjustable separately. On and off with a function key. Automated processes, automatic braking when an asymmetric track voltage is present (ABC procedure), pendulum automation (via ABC procedure), braking with direct current (Märklin brake section), speed-dependent on and off switching. Application examples: switching on and off the high beam or cab lighting. Shunting function by assigning the shunting gear and shunting light to the same function key. Automatic uncoupling, constant braking distance. On and off of outputs through the switch input. Automatic registration via DCC-A. Function outputs: assignment of functions to the outputs with Function Mapping according to RCN-227. Each function (F0 to F28, separately for forward and reverse travel) can be assigned one or more outputs.
