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 n+1Clock...

Follow the instructions in the installation ma- nual carefully, otherwise the ATEX-certification will repealed!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. The cable gland is suitable for cable diameters from 6.5 up to 8 mm.
