Asynchronous Serial Interface (ASI) – The asynchronous interface uses ASCII commands to control the flow of position data. Data is streamed in frames. Controller settings must be matched with the encoder settings to ensure that the data is communicated correctly.
Incremental Serial Interface (ISI) – By providing absolute positioning in an incremental fashion this interface gives positioning changes to the controller as pulses, using standard incremental channels (A and B plus compliments). Absolute position is maintained within the encoder and can be extracted by triggering the Load In/Load Out functions.
