StarTech NETRS2321E 1 Port RS-232/422/485 Serial over IP Ethernet Device Server

Connected NETRS2321E to a company time clock with a serial port to the Hyper-V guest running the time clock agent. Simple setup. Make sure to download current drivers from StarTech site.

Good product, but a bit pricey when comparing to RS485 to USB adapter. If you need RS485 to ethernet, there are not many options and this one works great. I got this to connect my Power One Aurora solar panel inverter to the PC monitoring software. In the StarTech manual, the pin-out was incorrect, +/- were reversed. After spending days to debug it, and with the help of another user of this NETRS2321E and the Aurora inverter on this Amazon site, I got it to work. Once I got everything configured, it has no problem. Other users have reported this unit may hang after many months of use. I haven't used this long enough to experience it yet.I took 1 star off due to the error in the pin-out in the manual.

I purchased this device to connect to a paging system for our hospital. I was able to get the device working in about 20 minutes. However, every few days the device would stop responding and would need power cycled. This caused ~1400 pages to fail to broadcast to our technicians. I had to decommission the device after 2 weeks due to it being unreliable. I'll be searching for a more robust solution. I should note that the device was installed in a climate controlled environment at a constant 65*F.

I spent 3 days trying to get the StarTech NETRS2321E to communicate with the serial ports on my Merlin Magix phone system. Contacted tech support via their Live Chat and was not able to get problem resolved. The problem was with the Virtual Serial port driver & software that comes with the unit. To get it to work I had to download and install "HW VSP3 - Virtual Serial Port" from HW Group (free download). The HW VSP3 software worked the 1st time with very little effort to configure it to work with the NETRS2321E.

I work with a lot of 3rd party devices to communicate with different industrial devices. Set up on these (I bought 2) were about as simple as it could be. No jumping through hoops to change the IP address, just a very simple program that was provided with it. Just the other day I had to change the IP address of an HP managed hub and had to connect to it via serial comms (not so easy nowadays) to change the IP address. What a hassle. Highly recommend this device.

Worked GREAT for controlling a MATRIX video switch over a home network.The unit has "froze" and had to be restarted a couple of times in a year. There is an update for it...if it fixes this "problem" this puppy is "perfect".

***EDIT****If you can spend a few more dollars I would recommend the  StarTech.com 1-Port RS232 Serial over IP Ethernet Device Server (NETRS232_1)  over this one. It's basically the same unit but has more features and a lifetime warranty. This IP server is still a great little unit, I just like the NETRS232_1 better.***EDIT****I am using these at work to add network support to some older serial instrumentation in the natural gas industry. These have worked flawless in the field for several months with no hangups or need for reboots. Also, these are well priced when comparing to competitors.My setup:Universal server -- polls IP port 502--IP / Serial Server -- converts IP to RS232 --Electronic Flow Meter -- responds with modbus RTU registers

Been ordering these for automation jobs and they always seem to work. We haven't had any come back DOA so that is a great thing. Always seems to get the job done. Thanks
