Servosila-SC-25-Connecting-CUI-Encoders-Technical-Note

Introduction
This technical note is written in regards to CUI Devices AMT233B-V absolute encoder, a 14bit
absolute encoder.
SPI vs. SSI
The encoder provides a “single-ended SSI” interface which actually more resembles SPI than
SSI (no RS422 compatibility).
The encoder should be connected to the SPI interface of the Servosila SC-25 motor controllers
rather than to the SSI/BISS-C interface.
When making a cable, refer to the datasheets of both devices to match SPI pins of the
corresponding connectors.
