I have purchased 2 - rs232/422/485 to Ethernet server made by waveshare. One I have connected to rs232 and have no problems. The second is for rs485. I cannot find were I can select rs485 as an option to make this work. (Waveshare shows this for other model rs485 servers) The page from your website says that it is transparent data transmission. I have gone a bit further and using a multimeter (true rms) I get no reading across A&B on powering up. I have searched online and I believe I should get a voltage reading between +/-1-5VDC, and this is so for other branded ethernet rs485 servers I have here. Your server seems to be stuck on rs232, and has difficulty registering rs485. Maybe this is a software fix? I have attempted to upgrade the firmware using the Vcom software interface, but I get error messages. Looking forward to hear if there is any support to get this server functional.

Hey @David205777, welcome to the forums!

Would you be able to share the error messages you are getting when you try and upgrade the firmware on this device?

This unit shouldn’t need you to flick a physical switch or change anything specific to work with rs485 but will likely require a software update out of the box.
