Overview
|
|
|
|
|
|
The Power-Line Modem (PLM) PICtail™ Plus Daughter Board provides communication over power-lines using a Binary Phase Shift Keying (BPSK) modulation scheme. These boards interface to the popular Explorer 16 Development Board and operate in the CENELEC C consumer frequency band at a carrier frequency of 129.6 kHz. The software modem runs on the dsPIC33F Digital Signal Controller (DSC) and utilizes an Analog Front End (AFE) to interface to the AC power mains.
Each of the communication nodes utilizes a high voltage (HV) adapter cable that connects the Consumer-Band BPSK-Based 7.2 Kbps Power-Line Soft-Modem to the AC mains. The HV adapter cable incorporates the circuitry required to provide the noise-filtering and isolation from the power-line.

Getting Started
|
|
|
|
|
|
To get started, two Explorer 16 boards with dsPIC33FJ256GP710A devices and two 9V power supplies are required for point to point communication. The Power-Line Modem (PLM) PICtail Plus Daughter Boards allow insertion into the Explorer 16 development boards in only one orientation. The demonstration software provides all of the source code required to implement power-line communication. In addition, there are also five different demos with example source code. Two Consumer-Band BPSK-based 7.2 Kbps Power-Line Soft-Modems are included in this kit. Explorer 16 boards can be purchased separately.
