SSI Protocol
SSI stands for Synchronous Serial Interface. SSI is an RS 422 serial interface widely used
with absolute encoders and controllers in a master slave configuration. SSI encoders offer
an all-digital, unidirectional point-to-point connection. For more detailed information see
the A36R Technical Reference Manual at encoder.com.
BiSS C Interface
BiSS C stands for Bidirectional Serial Synchronous, Continous mode interface. BiSS C is
B
similar to SSI and can be used uni-directionally like SSI; however, BiSS C also supports
bidirectional communication and operates at speeds up to 10 Mbits/sec. BiSS C can
address internal registers in the encoder that can be read and written to by the master,
allowing configuration and monitoring of the encoder not possible with uni-directional
communication. Reads and writes can be performed by the master on demand, without
interfering with real-time operation. This communication protocol is used by industrial
automation devices and a common high speed reliable digital solution between absolute
encoders and motion controllers. For more detailed information see the A36R Technical
Reference Manual at encoder.com
