The "DIDcoder" is an easy to use circuit board which counts quadrature incremental Encoder pulses and sends values to a CAN bus master. The circuit supports two encoder devices at once, and is suitable for mounting directly next to encoders, to digitize those devices.

The DIDcoder communicates on the CAN bus with a minimal implementation of the CANopen CiA-406 protocol. It supports 32 bit 4x quadrature decoding, pulse counting, index pulse, and value preset functions. LEDs indicate node ID and communications status.

The device is powered from 4.3-16VDC. The device has solder pads which allow easy chaining of devices. Device configuration is achieved via the CAN bus using LSS services.
