Combines a DCC Accessory Decoder, which can drive four standard servos, with a Monitor Unit with the same capabilities as an NCE Auxiliary Input Unit. Four of the Monitor Unit inputs can be used to report the position of turnouts driven by the servos, leaving 10 inputs spare for connection to block occupancy detectors or other devices. This second version has a link to remove power from the Monitor Unit, allowing the CVs of the DCC Decoder section to be programmed on a programming track.

Simple track occupancy detector for DCC model railroads with open-collector output to interface to NCE Auxiliary Input Unit - uses ZMCT103C (1000:1) current transformer rather than 300:1 devices

A DCC Accessory Decoder to drive four standard servos - based around an Arduino Nano 3 module and incorporating facilities for the precise manual adjustment of all servo throws (as well as via programming of configuration variables (CVs)). This updated version can be powered from a separate Accessory power bus, instead of directly from the DCC track, to reduce the load on the DCC Command Station or Power Booster.

When connected to the QuadServo-DCCDecoder, this keypad allows the user to adjust servo throws precisely via a series of keystrokes and to program the final positions into the Decoder
