Best RS232 over IP in the Business !!!

I have this setup to a US Robotics modem, and use Putty to telnet to port 100 of the serial server. The Web-UI has the baud rate locked at 115200-8N1. However, the modem keeps reporting the speed being locked at 9600, no matter what baud rate I put in the WebUI. I mean, I can deal with 9600, but still, I'd expect the WebUI to change the argument if it's an option.

Nothing in setup changes the arguments for serial.

I bought this device because the locations I'll be using in have a POE port but not a power receptacle. There's no excuse for why other very similar devices are supported by Windows 10, but not this device. I had to buy 3rd party software to use this device in my application. Once I found software that can work with this device, it does exactly what I needed it to do.

Very Disappointed

I had an issue with the first adapter, I could not update the firmware. But customer support was beyond excellent, and a new adapter was shipped to me. The adapter works right out of the box, and setup was easy and straight forward.

Works really well

Worked out of the box connecting it to an alarm system.

Easy to use and install

Just bought it, needed a poe rs232. This fit the bill, made the wrong assumption that it would be supported on newer OS Needless to say, I am not happy at my laziness.

Does not support win7/10

We use a StarTech NETRS42348PD device with their DS-Tool software (V1.2) and expected that this device would be seen by that software. It is not, and as such is of no use to us because we run Windows 7 or higher. This oversite should be corrected by StarTech.

Device not seen by Startech DS-Tool software

Can't use with Windows 7 or 10. Only works with older, unsupported operating systems.

Doesn't work with today's operating systems.

This worked well for us. The instruction could be better. But if you have setup IP addresses before the web tool is very easy to use.
