Waveshare RS485 TO ETH (B) Setup Guide

[Ndrinta]

This is a little quick start guide on how to set-up the Waveshare RS485 TO ETH (B).

You can set-up your device from the web interface (by simply browsing to the IP_ADDRESS of the device) or use the provided tool (recommended).

I'll explain how to set it up using the dedicated tool.
To do so, download VirCom_en.rar from here (make sure that the device is hooked up to you home network first), extract it and run the executable.

You'll be presented with this interface -> Click on the "Device" tab.

A new window will appear, you'll see your new device listed - Double click on this line.

And finally you are presented with the "Device Settings" window.

OPTIONAL: Right out of the bat, you can consider upgrading the firmware to the latest available at the moment (V1. 486 - April 2023). If you so desire, check the appendix at end of this guide.

Now, copy the following settings

Of course, ignore the IP_ADDRESS I used, you'll have your own.
Then click on "More Advanced Settings..." and enable the "Enable RS485 bus conflict detection, set 20ms (or something you're comfortable with).

OPTIONAL: You can also enable the Multi-Host setting, not required for a simple single-inverter installation.

• Appendix
  Firmware Upgrade:
  From the "Device Settings" window, click on the Firmware/Config button (at the bottom).
  NOTE: You will find these same instructions on page 48-52 of the user manual you can find online (or here)

You will first need to upgrade the "Code file" (aka bin file). Select the "Code file download mode" radio button, this will enable the related subsection, select the bin file using the "..." button on the right (you can download it from here) and press Download button at the bottom.

Then wait about 30 seconds for the device to finish the flashing (LED stops blinking).
Now select "Webpage directly download mode" radio button and select the folder containing the files (make sure you actually select the folder containing the files)

Hit Download again.
Wait 30 seconds, restart. Done. (you can verify the new FW has been flashed by going to the "Device Settings" window and check under the "Device Info" section that the "Firmware version" matches the one you just flashed).
