PL485-EK User Guide

Introduction

PL485-EK is an evaluation kit for the PL485. PL485 is a programmable System On Chip (SOC) for narrow-band

Power Line Communication (PLC) from Microchip Technology Inc, able to run any PLC protocol in the frequency

band below 500 kHz. Depending on the running firmware, PL485 is able to support applications not only for basic

connectivity (point to point or point to multi-point connectivity) but also for complex mesh network topologies.

The PL485-EK board has been conceived to communicate in the CENELEC B-Band (95 kHz to 125 kHz) and

complies with the CENELEC EN 50065 standard. It is designed to be directly connected to low voltage DC power

rails and optionally to AC mains by means of an external coupler accessory. Please refer to PLC-AC-Coupler User

Guide for more information about the AC coupler accessory.
