Hi
On Victron's accessory page I see a "RS232 to USB converter"
Does Cerbo GX have a driver for this? Why is it on the website?
I connected a similar Keyspan but Node-RED doesn't recognize it with nodes from node-red-node-serialport. same with other Tripp-Lite adapters.
This would open many possibilities to easly connect other devices to Cerbo GX.

I haven't used that exact USB to serial converter but I use a lot of RS485 to USB adapters and GX supports most serial converter chips out of the box.
Can you describe what you are seeing in NodeRed? Does it show up in the serial port list?
By default serial-starter will grab the Serial port and it will not be accessible from NodeRed but will still be in the list of Serial ports.
You have to remove it from Serial-Starter.

Hi
Bought a Raspbery Pi 4 to compare and develop before deploying to Cerbo GX.
On Cerbo GX doesn't look like Node-RED lists any of the devices plugged into the two USB ports. All I see are /dev/ttyS0, S3...S7 regardles of what I pugin. Firmware version is v2.92
On the Raspbery Pi 4 I installed the latest Venus OS and the same devices do appear in Node-RED. Firmware version v2.92
Why is there a difference on the USB devices listed between the two platforms?
Thanks
Closing this question:
The problem appears to have been the Tripp-Lite adapters I was using.
Switching to an FTDI adapter fixed the issue.
