The Utility-band BPSK 6.0 kbps PLM PICtail Plus Daughter Board provides a low-cost method for
the development and testing of utility applications implementing a Powerline Communication Soft-
modem (PLM), which is driven by a dsPIC33F Digital Signal Controller (DSC). The daughter board
operates at a utility-band carrier frequency of 72 kHz. 
Any dsPIC33F device with at least 2 Kbytes RAM, 16 Kbytes of Flash memory, four Output Com-
pare channels, one DMA channel, and one 12-bit ADC input (at least 500 ksps), can be used with
this daughter board. Please refer to the user’s guide for more details regarding the resource
requirements. 
The evaluation kit includes a pair of daughter boards and two High Voltage (HV) AC power line
adapter cables. Two Explorer 16 Development Boards (purchased separately - PN: DM240001)
are required to evaluate the daughter boards. In addition, two 9V power supplies (AC002014) are
also required. A Microchip programming/debugging tool, such as MPLAB

®

 ICD 3 or REAL ICE™

is required for programming or debugging the firmware on the dsPIC33F device.

The MPLAB Integrated Development Environment (IDE) should be installed prior to using a daugh-
ter board for application development. While MPLAB provides the assembler tools for develop-
ment, demonstration applications are written in the C language and require a C compiler to be
installed. Microchip’s MPLAB C compiler seamlessly integrates into MPLAB IDE. Both the MPLAB
IDE and MPLAB C compiler are available for download at 

www.microchip.com/MPLAB

 and

www.microchip.com/compilers

, respectively.

For free demo source code and more information, please visit the related web page at 

www.micro-

chip.com/powerline

. From the landing page, select Utility-band BPSK 6.0 kbps PLM PICtail Plus

Daughter Board. In the download section, select a demonstration application (such as the Ping-
Pong demonstration) to download an archive file that contains the related demonstration source
code files. Refer to the user’s guide in the download section for additional information.

After downloading the Ping-Pong demonstration application code and installing the development
tools, use the following procedure to run the demonstration:

1.

Insert a dsPIC33FJ256GP710A PIM into the first Explorer 16 Development Board.

2.

Plug a daughter board into the PICtail Plus expansion slot on the Explorer 16 Development
Board and connect the RCA jack of the HV adapter cable (provided in the kit) to the daughter
board.

3.

Plug the AC end of the HV adapter cable into a 110V/220V power outlet.

4.

Connect a Microchip programming/debugging tool to the Explorer 16 Development Board and
power up the Explorer 16 Development Board from the 9V power supply.

5.

In MPLAB IDE, double-click pingpong.mcp to load the Ping-Pong demonstration project.

6.

Choose your programming tool by selecting Programmer > Select Programmer, and then
choosing the tool to program the dsPIC33F device.

7.

Build the project by selecting Project > Build All.

8.

Download your code into the dsPIC33F device by selecting Programmer > Program.

9.

Repeat steps 1 through 8 for the second daughter board.

10. The demonstration code previously downloaded pings frames of data back and forth between

the two evaluation kits. Initiate the demonstration by pressing the S5 button on either of the
Explorer 16 Development Boards. The transmit frame count (TX) and the receive frame count
(RX) displayed on the Explorer 16 Development Board LCD screen should increment for both
of the daughter boards.
