RS232 <-> LAN
« on: May 28, 2024, 02:25:02 PM »

I have a device that communicates via RS232. There's an app on my computer that can control this device, and while I can very easily use a USB to RS232 dongle, what I'd prefer is to have an RS232 to Ethernet dongle so I can control this from a greater distance and also wirelessly. I have seen RS232 to Ethernet adapters like this: https://www.pusr.com/products/1-port-rs232-to-ethernet-converters-usr-tcp232-302.html and I assume they can "appear" as an RS232 device to the Windows control application?



Anyone done this with some success?

I had luck with one of these for an IT application (security system controller running on a virtual server). Reasonable price and support; worked well with Windows Server 2016 I think (its been a while).

Woah. Starting at $576! Good though to get some validation that these sort of devices work as expected.
With the cheaper ones (like the one I linked which is around US$40 or so) I'll have to buy somewhere that I can return it easily for a refund if it doesn't work...

You might search for "remote RS232", lots of little devices do that kind of thing.

I have a Moxa Nport which used to get used a lot, not so much these days so I don't know if the software is still compatible.

Digi makes devices that work great https://www.digi.com/products/browse/rs-232
I have used the Moxa and Digi boxes years ago to control XTA, BSS, Shure devices many times.

I use Global Cache' IP2SL frequently. They have a POE and WIFI version. Basically send the command strings to its IP address on port 4999.

Quite spendy as well. I'll probably opt for a device that costs 1/10th of that, seeing as it's not mission-critical.

That's the guy. I use these to operate serial port control ptz cameras over ethernet. Been flawless for several years. $30 each.

There are Rs-232 to ethernet converters, mostly used for industrial machine control.  I used to have some Digi units both rj-45 and wireless that I used back when I was still using the original drive racks. There are still current products/drivers available.

Moxa nPort
used them for years.  My oldest is from 2004 and it still works fine
Also known as "device servers" and as someone else pointed out, are a mainstay of industrial automation.
