Usr-Tcp232-410S RS232 / RS485 Serial to Ethernet Adapter/IP Device Server Ethernet Converter Support DHCP/DNS (1)

Used 2 of these to extend the 485 buss from an Avigilon V1000 Embedder controller that normally will not support V2000 ethernet 2 door controllers. I set up a point to point bridge to a building across the street. 250mb connection. Then used V100 door controller with 485 in. Once i set up the host and client then set the correct baud rate they connected. My access card swipes and open time are fast. Good product. They come with a fixed IP address of 192.168.0.6 or .7 no printed instructions. So make Shure you have internet access during you install.

I received the product via Express Mail (not courier) ahead of schedule ( good surprises still happen ! ), packaging was very good and included the power supply 5V/1A and an RS232 Cable as well. Logged into the device with no problems, very easy to use interface in it's software setup. Product was shipped via Expedited Mail (not courier) and arrived ahead of estimated schedule, always nice ! Only 1 critique, no information at all in the package in regards to where to get doc's, manuals & the software app that can be used for configuration. Although this is not really needed, it would be nice if a purchaser did not have to "hunt" for that info if bought through Amazon. If bought direct, not a problem as that is all there on the site.

Not sure why they are not included, especially when the IP is set to static (192.168.0.7) in default and the pw un is admin/admin. I guess the only people that buy one of these already know how to set it up. I have had it for a week and just now got to the web interface so I dont know if it works but progress I am making progress. Good luck

Cannot access web page after 1 week. I have several of these and now replacing all with a different manufacturer as half of them loose access to the web page and seems that they are unrecoverable by resetting to MFG settings. It pings. Some units continue to process data, but you cannot get into the device via port 80 webpage. Some units continue to work fine. Some are just dead. About 50% Failure rate.

Perfect

I had extreme trouble getting these to work. I was trying use the ethernet to rs485 conversion feature this promises but it does not work if your end terminals are not PCs. Plus when they do work, it used to be momentary and then stop. Even their customer service did not understand why our setup (1 as tcp server and other as tcp client) would not work. Ended up returning it and buying an expensive product to achieve my goal

Nice device and work

Tried pairing this with a RFD900 radio modem for use with a UAV ground control station. GCS is complaining about unknown packets. Both Mission Planner and MAVproxy never get the heartbeat to initiate communication. Web interface sucks and has limited options. For the price you are better off just getting a Raspberry PI and rolling your own. Or you can waste your Saturday afternoon trying to get this to work.

Je cherchais un convertisseur de ce type pour domotiser ma chaudière De Dietrich. Ce modèle fonctionne très bien contrairement au modèle USR-TCP232-306 que j'ai dû retourner parce qu'il ne m'envoyait des infos qu'au démarrage de ma chaudière. Il gère me Modbus TCP et le Modbus RTU over Ethernet. J'aurais bien mis 4 ou 5 étoiles car le produit fonctionne bien mais le fabriquant est par contre peu fiable. Sur la fiche descriptive du produit, sur le site officiel, il était indiqué qu'un firmware MQTT allait être disponible. Par chat, le support m'avait parlé de septembre 2019. Maintenant, l'info a disparu et ils ne répondent pas à mes mails. On voit donc le peu de sérieux de ce fabriquant...

Pro: USR has been around for long time making products like this and it shows. unit has handy size and metal housing, can be powered by own PSU (barrel jack) or external supply (wide range, 5-30V) which makes it easy to install anywhere. all terminals are pluggable. has two ports which can be used simultaneously (one is 2-wire RS485, the other is RS232). easy to configure via web browser, has own packet sender/monitor for diagnostics etc. Con: None that i can think of... EDIT: if you are interested in using virtual COM ports, you need to use VCOM software. several versions are available. they all seem to work and seem to be bilingual. version (V3.7.2) defaults to English. Versions 4.0 default to Chinese.

Bought this to connect my Solar Inverter to my Home Assistant set up. Worked perfectly out of the box. Impressed.

Super einfach einzurichten. Macht nun schon einige Wochen genau das, was es soll.

l'ho comperato per interffacciarmi via modbus alla mia pompa di calore immergas. le difficoltà integrate sono legate alla logica di comunicazione modbus non ben documentata da parte di immergas. lui funziona egregiamente ed è molto versatile e configurabile
