USR-TCP232-302 Tiny Size RS232 to TCP IP Converter Serial RS232 to Ethernet Server Module Ethernet Converter Support DHCP/DNS (1)

Got this to work with an ALLEN BRADLEY SLC 5/04 PLC processor. Had to take it out of it's metal case because I did not have a Male to Female DB9 cable at the time. At first it wouldn't work because I had a null modem adapter between the usr and processor. The pinout in the manual for the usr led me to believe that i needed to flip flop the Rx & Tx lines. But after removing the null adapter, it worked. So either it was wrong, or the pinout for my PLC was wrong. I got it setup up on a static IP on my home network and can access it anywhere with anything (including VNC'ing into my server with a smartphone from work. I was able to go online with the PLC from 3 different computers at the same time even. It did take some time setting up the serial comms options so it's not a "Pull it out of the box, plug it in and it works" thing. If baud rate, parity, RTS, DF1, CRC, or packet size are foreign words to you, buy this at your own risk. Or actually, do buy it. If you don't know anything about how RS232 comms work, this would be a great learning tool. If it works on ALLEN BRADLEY'S proprietary DF1 protocol (which this thing does not know what that is and nothing else on this planet uses it), then it will work on anything.

bueno

Does what it says and appears reliable, but the documentation is very poor (come on guys, hire an English tech writer for a week). If you understand how such things work, you can easily overcome the documentation. But if you do not know the basics of serial transfer and TCP/IP - then best to get someone who does to assist you. Solves the problem at less than half to cost of other solutions.

Does not support serial flow control, like XON/XOFF or RTS/CTS. This means that if you are sending to a serial printer, the converter does not recognize the printer saying 'stop for a bit' as it is processing the received serial data. This will cause loss of serial data (and failed printing) if the printer's input buffer overflows.

I connected it up to an ancient lab moisture measuring instrument with a com port, connected the other end to my network, installed their software (Windows 10) and within a few minutes was reading data! I was stunned how simple it made dialing in the configs. Really excellent, easy to use software, solid hardware. This thing is going to solve a lot of interface issues for me as we digitize our older lab instruments.

I got no response from my Agilent 34401A DMM. A Gearmo RS232 to USB worked for me. I never get RS232 to Ethernet devices to work - a general statement.

Perfect for accessing a serial port, over the internet, on your PC. I use the old Hyper Terminal program from the Windows XP days as it still works on newer operating systems. But there are other ways to access as well.

If you need a cheap way to send serial command over IP, then this works great. It's built well, can act as either a server or a client, and works with Bitfocus Companion if you need that!

Excelente producto.
