PICtail Plus Daughter Board Microchip AC164142
Consumer-band BPSK-based 7.2kbps Powerline Softmodem PICtail Plus Daughter Board
Detailed Description
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 Demo Board and operate in the CENELEC consumer frequency band at a carrier frequency of 129.6kHz. The software modem runs on the dsPIC33F 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 7.2Kbps Powerline Softmodem to the AC mains. The HV adapter cable incorporates the circuitry required to provide the noise-filtering and isolation from the power line.
Features
- Operates on 5V and 9V power supply
- Modulation & demodulation in software
- Software selectable baud rates: 1200, 2400, 3600, 4800, 5400 and 7200
- Variable transmit power level setting
- Compatible with 220V/50Hz and 110V/60Hz power lines
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 7.2kbps Powerline Softmodems are included in this kit. Explorer 16 boards can be purchased separately.
