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.

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.

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.

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

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.

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.

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

The NETRS232485 Serial Device Server lets you remotely manage an industrial RS232/422/485 serial deviceover a local or wide area network (LAN/WAN), with redundant power inputs and dual 10/100Mbps Ethernetports.To minimize downtime, this intuitive dual Ethernet serial over IP solution maintains connection to your criticalequipment by automatically switching to its secondary LAN port within 10 milliseconds of a network failure ordisruption.
Redundant dual Ethernet ports with < 10ms recovery time
Up to 460.8 Kbps baud rate
IP-30 industrial casing and extended operating temperature range
Redundant power input via 12-48V DC terminal block or optional 12V DC power adapter
Supports RS232, RS422 and RS485 serial protocols
Supports ICMP, IP, TCP, UDP, DHCP, BOOTP, ARP/RARP, DNS, SNMP MIB II
SSL, SSH and HTTPS data encryption and security protocols
Wall or DIN rail mountable
Configurable via software utility or web browser
8KV air and 4KV contact ESD (Electrostatic Discharge) Protection
Simultaneous connection with up to five host devices
Ideal for industrial environments, the serial to Ethernet device server accepts wide-range 12-48V DC powerinput via a terminal block or an optional DC jack, enabling you to add redundant power with a secondary adapter(e.g. 12V DC 1.5A Power Adapter SKU: IM12D1500P - sold separately), keeping the device server functional inthe event of power surges or failures.This device server supports baud rates up to 460.8Kbps which provides a smooth, high-speed connection toyour serial devices.
The device server also offers support for HTTPS, SSH and SSL to ensure securecommunication, while integrating remote Telnet configuration and support for IP, HTTP, ICMP, DHCP, TCP andUDP protocols.
