Position data are transferred synchronously using the SSI protocol (SynchronousSerialInterface). FM 352 only supports GRAY code. Due to the arrangement of the data bits in the transferred frames, the data formats "fir tree", "half fir tree" and "right-justified" are used. More info you could find in manual in Entry ID: 2103044 Best regards, Hristo Mihalev
