StarTech.com 1 Port RS232 to Ethernet IP Converter / Device Server - Aluminum - Serial over IP Device Server - Serial to IP Converter (NETRS2321P)

Great to redirect Com ports across network. Shame can only do one port to one end point

Poor user interface. Product doesn't work with a 40m network cable.

Quality product and great service

We wanted to use this with our HVAC system at work, I didn't get it working, and don't actually know why. It did work to run a zebra train ticket printer fine but the HVAC system we have didn't work with this or with a different brand unit I bought. However it works on a physical serial port and on a usb converter fine.There are many applications for this and the web setup interface is easy to use. When I was looking for one of these devices, this was one of the cheeper options. StarTech I have used before and have some faith in after an issue with another product of there's I bought failed. Their customer support was second to non sending out a new unit and not requiring me to return the broken unit.I still don't know what the issue with the HVAC interface was, I don't think it was an issue wholey with this device as I said the other unit (in the £300+ region) also didn't allow me to control or communicate with the controller on the HVAC.

Unit works very well. I have serious issues with it defaulting to 192.168.1.1, but easily resolved when I realised that the software it comes with is next to useless. The good news is that it you can configure form a pure web interface. Very nice !

Hardware wise it’s up to the usual high Startech standards.Horrible user interface. If you think of a 90s era web site you are probably approaching the quality of the web interface. Interaction is painful.I sent the item back.

Product is exactly as advertised

Works well, just remember that a driver on the host computer must be installed. I did not have difficulty configuring this unit, but have a history with serial ports and comm settings.

Have to admit, after initial trepidation and frustration, this thing is doing exactly what it is supposed to do. Has been running for a week with no hick-ups.I did give it a reserved DHCP address in the router, which can never hurt with these things. They tend to get confused when the IP address changes and StarTech support chat advised against DHCP period, but that's silly. The support over chat seems to be lacking, but they do try.As others have mentioned, the software is absolute crap. It looks like the worst sort of hobbyist Windows garbage from last century. It's also buggy, overly complicated and apparently loses all of its virtual COM port mappings every time it leaves memory. Yes, really; you have to reconfigure the thing every time. It also randomly exhorts that it should be run as an administrator. Tried that and had no effect. Oddly, it seems that the auto-start setting in the first menu is the thing that triggers this order. Currently have an alert box stuck that can't close, but it isn't affecting the COM port operation.Speaking of the COM port, it is running flawlessly on Windows 10, and haven't yet had it crap out. Will see how that goes, but five stars so far.UPDATE: Ran like a champ for three months. Then it was time to finally update Windows 10 and restart. Was not looking forward to it, due to the incredibly bad UI. Once the machine rebooted, opened the application to see no devices and no COM port mappings (of course). But then... I looked at my alphanumeric sign and it was updating. Amazing! Closed the crappy UI and won't worry about why until the next restart. Hopefully it managed to set itself up as a service, but hard to tell from all of the odd messages I got on trying to set that option. So still 5 stars, despite the -10000 stars UI. :)

Great device for Ethernet to rs232 conversion. Little expensive but needed.

funktioniert einwandfrei, lässt sich tadellos via Browser konfigurieren, kann via DHCP (Reservierung) konfiguriert werden, ist absolut stabil auch bei oft hohen Datenmengen. Klare Empfehlung
