CY3274-HV PLC DEVELOPMENT KIT

QUICK START GUIDE

Using the CY3274-HV High Voltage 110-240 V AC PLC Development Kit

To evaluate this kit, a second CY3274 kit is needed. This guide assumes that two CY3274 kits are available.

1. Install CY3274 Kit installer from the kit website. Open PSoC

Programmer from Start menu.

2. Set AutoDetection to Off, set the ‘Device Family’ to

CY8C-PLC-LED16P, ‘Device’ to CY8CPLC20-OCD, programming

mode to Reset and Verification to either option.

3. Open the CY3274_PLC_Demo.hex file from the firmware ->

CY3274_PLC_Demo inside CY3274 kit installation folder.

1. Connect the USB cable from the PC to the MiniProg programmer.

Connect the MiniProg to the ISSP header J21 on kit 1.

2. In PSoC Programmer, power the device by clicking ‘Toggle Power’

button. Click the Program button (downward arrow). When the

status says ‘Programming Successful’, remove the MiniProg from

the ISSP header.

3. Repeat the above programming operation on kit 2.

1. Connect the LCD Module to LCD1 header.

2. On kit 1, connect a jumper wire from SW (on J18) to P0[1] (on

J13), from P0[4] to one of the 8 DIP switches on J12 (the 8 DIP

switch array on S3 is connected to J12) and from P0[7] to another

DIP switch.

3. Repeat steps 1 and 2 on kit 2 as well.

4. Put the 2 DIP switches (S3) on kit 1 to ON position to set it as Tx

and the 2 DIP switches on kit 2 to OFF position to set it as Rx.

1. Connect the power cable from the AC mains to the AC power

connector on the first CY3274 kit. The blue LED (DS1) turns on.

Repeat the same for kit 2.

1. Push the reset button S2 on both nodes. A message “PLC Demo”

initially appears on the LCD. The kit will be a transmitter if the DIP

switch connected to P0[7] is pulled high, else the kit will act as a

receiver.

2. Press the push button (S4) on transmitter to start transmission of

packets upto a packet count of 1000. The LCD shows transmission

statistics.

3. Transmission can be started or halted (if transmission is in progress)

or resumed (if transmission is halted) or restarted (when the packet

count of 1000 is completed) by pressing the push button (S4) on

the transmitter kit.

4. Received packet count can be reset by pressing the push button

(S4) on the receiver kit.

CAUTION: High Voltage (Risk of Electric Shock)

All work in powerline communications must be done with extreme care.

Caution must be exercised when using power supplies or power related equipment.
