This section describes how to set up two PLC boards and transmit a packet from one board to the
other.

are connected to the powerline.
2. Connect five pin header of the CY3240 USB-I

C bridge to the I
2
C header (J15) on the PLC kit
and other end of the bridge to the computer's USB port. Make sure that a jumper shunt is
connected across J1 on the bridge. When the bridge is connected to the USB port, the green
LED turns on.
3. Make sure there are no jumpers placed on the PLC board.
4. Open the Control Panel from
Start > All Programs > Cypress> PLC Control Panel
.
5. The connected bridge appears in the USB-I
2
C bridges list under the main menu of the GUI.
Select the bridge from the list and click on Connect. Make sure that the
+5 V PWR
option is
selected and the slave address is 0x01. The I

C frequency can be any of the available options.
The red LED lights up on the bridge if the connections are correct. The GUI indicates successful
connection by briefly stating “PLC #0 Connected” in the status bar on the bottom left.
