For EMC:



a Transil™ diode SMC30J30CA is placed on VCC track to protect the ISO8200BQ

against surge discharge



for common mode surge testing, solder two single-layer capacitors C1 and C3 (not

included) at the predisposed locations



22 nF capacitors are included on the output lines for burst disturbance filtering

To supply the load, connect the supply voltage to the J1 2-way screw connector.

The load is connected to the 8-way output.

Access mode

Configuration

Direct access

connect the center pin of J4 to GND

Synchronous access

connect the center pin of jumper J4 to 3.3 V

Once the selection is configured, push the blue user button on the STM32 Nucleo

development board to begin evaluation.
