Line 14: The CLOCK and DATA signals are transmitted according to RS-422 standards. RS-422, also known as ANSI/TIA/EIA-422-B, is a technical standard that specifies the electrical characteristics of the balanced voltage digital interface circuit. Data is transmitted using balanced or differential signalling i.e. the CLOCK and DATA lines are basically twisted pair cables. Inputs can use an [[opto-coupler]] for [[galvanic isolation]] (For more details see [http://www.posital.sg/sg/products/POSITAL/AbsoluteEncoders_Context/AbsoluteEncoders_Context_Technology_SSI_AppNote.pdf]) that can be driven by RS-422/485 levels. The DATA output of the sensor is driven by aan RS-422/485 line driver. Differential signalling improves the resistance to electromagnetic interference (EMI), hence making it a reliable communication channel over long transmission lengths and harsh external environments. == SSI design ==
