Pinout

The following points should be considered during design phase and installation:

Notes for routing and installation The SSI information (Clock and Data) are transmitted as differential signals. To ensure a good EMC immunity, also for long distances, shielded cables with twisted pair conductors should be used. The cable shield should be connected to earth at both channel ends and the two end devices should be always at the same reference potential. When using externally shielded cables, particular care should be paid, not to damage or to interrupt the shield itself. Shield should be connected near by the connector. Refer also to the corresponding notes of the sensor manufacturer! Refer to the guide lines in the design guide for the EtherCAT plug-in modules to ensure a proper routing of the differential signals! The value of each termination resistor should be equal to the cable characteristic impedance, typically 120 Ω for EIA-485 or RS-482 standard. Routing of the differential signals should be impedance controlled with typically 120 Ω for EIA-485 or RS-482 standard. Traces wide should be > 0.2 mm, the maximum ampacity need to be taken into account. To improve the EMC immunity it may be helpful to connect the two signal channels on two different connectors
