Serial to WiFi Ethernet Wireless Converter RS232 RS485 Serial Server(USR-W610)

I am using these as a wireless bridge from a main control panel to a rotating drum. The transceiver on the drum is powered by a rechargeable battery. This allows me to transmit temperature wirelessly from a temperature card that communicates ModbusTCP via the RJ45 port. I have configured 2 of these W610 to work in a pair, 1 is set for AP and the other as STA. This provided a long sought for solution for a wireless bridge for ModbusTCP that is stable, and done with consumer grade hardware. Delighted with the results.This review does not include all the details of the use case.Later, 7/16/24I have read some reviews that are 1 star. Admittedly, some in depth knowledge is required to explore all the capabilities of these W610. Our team has created a Python script that can set the parameters/configuration to our needs via the Serial port.If you can't find the user manual, try this link: https://www.pusr.com/uploads/20240614/44573feb206c5d3ac878a7113c7495a8.pdfWe have successfully been using these for 1: A wireless bridge for I/O modules communicating ModbusTCP 2:Remote slave panels with analog and digital signals controlled wirelessly 3: Ethernet to RS485 convertor to communicate/convert ModbusTCP to ModbusRTUWe have purchased 20 units already, so far the performance after correct configuration for the application has been stable, predictable, repeatable.The manual may be challenging to understand since it most likely was translated from Chinese, but a careful study of the pictoral illustrations can help.A pair of these configured as AP and STA to our specs allowed us to use a PLC to send frequency and run commands to a VFD. The PLC connects to the AP via Ethernet cable. The VFD connects to the STA via 2 wire RS485. The PLC sends ModbusTCP commands and the USR-W610 STA unit converts the signal to ModbusRTU. The setup as Wireless has an observable lag/latency while the Ethernet wired setup has no observable lag.IMO these are worth the time/learning curve if you plan to use multiple units. Admittedly the details of configuration are numerous enough that much may be forgotten durng irregular use and configuration.The only thing we would caution against is using these for any internet traffic, of which the W610 is highly capable. Most of these devices require in depth knowledge on both hardware and software levels to secure properly against data breaches, embedded spying, ransomware, and other such digital atrocities. You have been warned.

This thing works great with my vinyl cutter. I used to have a 20' cable between my vinyl cutter and my desktop however the cable was always a tripping hazard which I know I personally have tripped over a few times. That said, the device works better than expected, however setup was not for the faint of heart. I had quite a bit of difficulty getting this to connect to my wifi. the instructions were not very clear and I wasn't 100% sure of how to connect it. that said, once it did connect, it hasn't dropped off wifi once, and remains reliable, so that is a definite plus.

I got two of these to connect to the serial ports on video projectors. Not much in the way of documentation, but they are easy enough to set up. So far they are working well. No issues dropping off the WiFi or anything.

The instructions are very poorly written (when you do find them via google).I put an older version in about 5 years ago and had it working and a modbus tcp gateway and also in bridge mode so I can use the Eth port. But it's been a long time and I cannot remember how I got it working. I've spent a lot of time trying to recreate this connection but it doesn't work.

Calidad del producto y puntualidad en la entrega

I've been using two of these for ongoing monitoring of power meters and a well depth monitor. Once I got them setup they say on the network and have transmitted ~1second data for a couple of years with no issues.

This has probably one of the worst interfaces I've seen in awhile as far as its English interface pages goes. That said, I was able to successfully use it to establish a terminal session between a laptop and a Compaq Portable so it does work. It does have an ethernet port, and supposedly can bridge network traffic as well, although I haven't tested that as of yet.

Works great! Exactly what I was looking for. Serial over WiFi tcp/up. Countless applications
