2.2 Power Requirements

The RS485FLDPLXDRCEVM is ready to operate immediately outside of the box. To power the board, find J5 at the top center of the board. For systems with both GND and EARTH signals, attach the EARTH lead to the left most pin of J5 next to the text that displays EARTH and attach the GND lead to the center input of J5 above the text that displays GND. With systems with just a GND signal, EARTH can be left floating or connected to GND. The positive terminal of the power supply attached to the right most pin of J5 next to label displaying “VCC”; a 3 V to 5.5V supply can be used to operate the default IC, THVD2412DRC, in place on the board by default. For other devices that can be used, refer to specific device data sheet.
