The IzoT CPM 4200 Wi-Fi EVK includes two IzoT CPM 4200 Wi-Fi EVBs that come pre-configured with a digital I/O (DIO) example application which uses Interoperable Self Installation (ISI) to automatically install and configure the devices, and can also be installed and managed with the IzoT Commissioning Tool. The EVK also includes a Wi-Fi access point, and the EVBs are pre-provisioned to use the Wi-Fi network hosted by the Wi-Fi access point.

To setup the Wi-Fi EVK and run the DIO application on the two EVBs, follow these steps:

  1. Connect the antennas and the power supply barrel connector to the supplied Wi-Fi access point. Make sure the ON/OFF switch at the rear of the access point is pushed in. Connect the WAN connection at the rear of the Wi-Fi access point to your Internet connection using the supplied Ethernet cable as shown below. Plug in the power supply to the mains and make sure that the front panel LEDs are illuminated.

             

  2. Connect your computer to the access point’s CPM4200_EVK Wi-Fi network; the authentication is set to WPA2-Personal and the security key is echelonizot.

  3. Ensure that you have an Internet connection. If not, consult the Wi-Fi access point’s user’s guide. You can connect to the Wi-Fi access point with a browser at the 10.5.0.1 IP address; the user name is admin, the default password is admin.

  4. Connect both of the Wi-Fi EVBs to your computer via the supplied USB A to USB Micro B cable connected to the lower port of the Wi-Fi EVB as illustrated below. The USB connection to the computer provides power to the board, provides a debug interface and a serial console. Windows will automatically install drivers for the USB debug interface.

  5. The DIO application has a block that represents a digital state that controls a hardware digital output that controls the LED D8 and a LonTalk/IP network output reporting the state. You can control the digital state with a hardware switch input (SW1) and also with a LonTalk/IP network input.

  6. Once powered up, the Wi-Fi EVBs will connect to the access point, automatically find each other and connect the block on one device to the block on the other. Once connected, you can press SW1 on one Wi-Fi EVB to control both the local LED D8 and the one on the other Wi-Fi EVB.

  7. Each device also has a Connect button controlled by SW2 that you can use to add a device to the device list in the NodeUtil Device Utility included with the IzoT CPM SDK. You can also use the Connect button to create, modify, and delete connections.
