Synchronous Serial Interface (SSI) Driver Driver meets EIA standard RS 422; transmission rates up to 10 MBit/s Transfer Transfer distance up to 1,200 m Transmission Balanced transmission provides high noise immunity Pair lines Shielded and twisted pair lines are essential to attain extremely high noise immunity Interface For a detailed description of the synchronous-serial interface (SSI) refer to introduction section. Optional Built-in RS 422 interface for bus mode (strobe-function). Up to 32 encoders (AWC) can Single Shift be used on the same data line ! > Taktsequenz 1 2 3 4 5 6 n...

Follow the instructions in the installation ma- nual carefully, otherwise the ATEX-certification will repealed! > Signal lines and power supply are connected via screw terminals in the connection cap. The connection cap can be opened for installation by removing the six cap screws.
