A decoder is a device which listens for Digital Packets addressed to it, and then performs whatever action is requested.

There are three types:

1. Multifunction Decoder,
2. Function Decoder, and
3. Accessory Decoders.

Some multifunction decoders are very simple devices providing only motor control and a small selection of lighting options, while others are very complex with multiple special effects, tunable motor response, and sound effects available.

Function decoders are similar, except they lack the motor control functions.

Accessory decoders are used for turnouts, signals and other animated items.

Please see the decoder page for full details.
