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.
Contents
• Welcome letter
• Board:
– One PL485-EK board
• Cable:
– One Micro A/B-type USB cable
Kit contents are protected with anti-static foam. The PL485-EK board is shipped in an anti-static shielding bag.
WARNING
The board must not be subject to high electrostatic discharges. It is recommended to use a grounding
strap or similar ESD protective device when handling the board in hostile ESD environments. Avoid
touching the component pins or any other metallic element on the board.
Features
