PL360G55CB-EK User Guide
Introduction
PL360G55CB-EK is an evaluation kit for the PL360 modem. PL360 is a programmable modem for
narrow-band Power Line Communication (PLC) from Microchip Technology Inc, able to run any PLC
protocol in the frequency band below 500 kHz. The PL360 has been conceived to be driven by external
Microchip host controller devices; in this case a SAMG55 ARM® Cortex®-M4 RISC processor is used. The
Microchip host device loads the corresponding PLC-protocol firmware and then controls the PL360
modem operation.
The PL360G55CB-EK board has been conceived to communicate in CENELEC B-Band (95 kHz to 125
kHz) and it complies with CENELEC standard EN 50065 regulations and Smart Energy applications. It
can be connected directly to AC mains or DC power rails.

1. Evaluation Kit Specifications
CAUTION
1.1 Safety Recommendations
This evaluation board must only be used by expert technicians. The PL360G55CB-EK board is powered
from a DC power source, so only the PLC coupling stage could have a hazardous voltage when is
connected to mains. The risk of electric shock is minimized since all required connectors and
configuration jumpers are galvanically isolated from the coupling stage.
Be careful, there is risk of electric shock in the PLC coupling stage. A normal use of the
PL360G55CB-EK board is for indoor use only.
This evaluation board does not have any switch on mains connection to switch it on or off.
To avoid damage of measurement instruments, do not connect any probe to the high voltage sections if
the board is not isolated from the mains supply.
Temperature operating range should be from 0ºC to +85ºC. Running extended periods at minimum and
maximum values may cause permanent damage to the board. Quartz crystal components could not cover
previous temperature range with desired performance due to aging.
PL360G55CB-EK
Evaluation Kit Specifications
The evaluation board is intended for further engineering, development, demonstration, or evaluation
purposes only. It is not a finished product, unless otherwise noted on the board/kit.
Important: Microchip does not assume any responsibility for the consequences arising from
any improper use of this board.

Kit contents are covered by anti-static foam. The PL360G55CB-EK board is shipped in an anti-static
shielding bag.
The board must not be subject to high electrostatic discharge. We recommend using a
grounding strap or similar ESD protective device when handling the board in hostile ESD
environments. Avoid touching the components’ pins or any other metallic elements on the
board.

PL360G55CB-EK
Getting Started
Take into account that the connectors to supply the board are different than the one for PLC signals. The
board can be supplied by three different ways:
• +5V from USB Micro-B connector (J4)
• +5V from mikroBUS connector (J6)
• DC voltage (from +6V to +30V) from DC Jack connector (J8)
2.2 Running Preloaded Firmware
Once the board is supplied, LEDs will show activity. The PL360G55CB-EK board is delivered with a preprogrammed application in SAMG55 Flash memory: the G3-PLC PHY Tester for CENELEC B-Band. PLC
communications are developed for CENELEC B-Band in AC or DC voltage grid.
The kit includes a USB 2.0 type A to Micro-B cable that can be used to connect the board to a computer.
Connect a suitable cable in the PLC connector (J1) and plug it to an AC/DC voltage grid to communicate.
By means of the PLC PHY Tester PC application, it is possible to send and receive PLC messages using
the PHY layer in the CENELEC B-Band according to the binary flashed in PL360G55CB-EK board.
2.3 Code and Technical Support
Firmware developers can not only run the given example code, but also implement their own applications
based on the provided firmware stacks.
