Did you just buy your new NetGuardian RTU and you are thinking how easy it would be if you could do the initial setup on your phone? Well, you actually can.

The process is quick and simple, and it shouldn't take you a long time. But, of course, if you need further help you can always contact our tech support team.

So, let's walk through the step-by-step on how you can set up your NetGuardian for the first time through your phone.

Step-By-Step

  1. Connect the included cable to your NetGuardian through the front panel CRAFT port (DB9 or USB-B).
  2. Connect the other end of the cable (USB-A) to your mobile phone.
  3. On your phone, download the free app called "Serial USB Terminal" or any similar app.
  4. Setting your RTU through your phone
  5. Open the downloaded app. You should see the message "USB device detected".

  7. Click on the menu button on the top left of the screen and select "Settings".
  8. Setting your RTU through your phone
  9. Under the "Serial" header, you'll need to fill in the following values:
    • Baud rate: Check the user manual for the device. Typically 9600 or 115200. If you see weird characters after connecting, the baud rate is most likely wrong.
    • Data bits: 8
    • Parity: none
    • Stop bits: 1

  11. Under the "Terminal" header, you'll need to configure the following settings:

    • If the device is unknown you'll need to assign the driver depending on the connection type. DB9 is typically PL2303 and USB-B is CDC.
  19. Setting your RTU through your phone

    • If you are seeing a "connection failed" error, try doing a long press on the device in "USB Devices" and changing the driver until you get a Connected to X device.
