Rail-Mount Serial Server, RS232/485/422 To RJ45 Ethernet Module, TCP/IP To Serial, POE Function Optional
Features At A Glance
This is a RS232/485/422 device data acquisitor / IoT gateway designed for industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc. The module features RS232/485/422 and Ethernet port (PoE function optional), uses DC port (outer diameter: 5.5mm, inner diameter: 21mm) and screw terminals for power input. The case with rail-mount support, small in size, easy to install, cost-effective. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring...

I used to use Lantronx Xpress DR's a lot, this is a great replacement. The software and documentation needs some love and attention, I struggled with a issue for an hour or two, it was a broken wire (not the devices fault) but the documentation was hard to follow so I was not sure if I was missing something on that end.I love the MQTT functionality.So far its been running really reliable. I am feeding power to this from a POE Stripper to bring the voltage down to 12VDC to also feed my end deviceNote: If you use MQTT it wipes the web interface

So the documentation isn't great, so here's the steps I took to connect this to my MQTT server (which took about an hour of testing to figure out):You'll want to start by grabbing a RS232 to USB cable and go over to the Waveshare website and look up the support page for "RS232/485/422 TO POE ETH (B)". On the page there's a link to the VirCom English software you'll want.Hook up the device to the RS232 and POE, plug the USB end of the cable into the PC, launch the software, hit cancel if there's a Windows Firewall popup (at least you shouldn't need to allow it for initial setup), then click the Device button. Double-click your device from the list (there's probably only going to be one listed), then set the IP Mode to DHCP (this will save some headache in the long run unless you really want a static IP for some reason). You can also tweak any other settings you might need to change (in particular, make sure the Baud rate, etc. matches whatever you plan to hook up to it). Click Modify Device to save this setting.Next, you'll want to create an empty folder somewhere on your hard drive that you'll be able to easily find later. Then back in the Device Settings screen, click the "Firmware/Config" button. In the top section "Webpage Directly Download Mode", click the [...] button on the right and then navigate to the empty folder you created. Click the "Clear All" button, then click the "MQTT Config" button, which will bring up a (thankfully pretty straightforward) dialog box to fill out your MQTT Server settings. Click save, then at the bottom of the previous screen click "Download" to update the settings on the device.At least in my case, this was everything that was needed. You can test by launching PuTTY or similar - any button press in the terminal window will generate a MQTT message in the publish topic, and any messages sent to the subscribed topics will be printed in the terminal window. At this point, you should be able to uphook the RS232 cable and hook up the gateway to whatever device you were wanting to use it with.As for an actual review... the price is absolutely right on this thing and it's got some nice features, so I can't give it too bad of a review. I am knocking off a star because of the somewhat confusing documentation, the lack of options available from the web UI (no MQTT settings, for example), and needing to use a somewhat sketchy program to configure it.

I was able to get into the web interface and program this unit once I found the IP address. I believe I had to use 192.1681.254 to access the web interface after factory reset. It was not 192.168.1.200 like the manufacturer website suggested. Accurate documentation turns this into a 5 star review.Otherwise, it did exactly what I wanted it to do. The POE functionality does what it’s supposed to. Keep in mind it uses 48V POE. Most enterprise equipment switching does this by default. At the end of the day, it is used as a print server for my ImageWriter II.You also can’t rename the device out of the box. Legend has it there is a special firmware that unlocks this capability. I only have one of these, so I’m not losing sleep over it.

There is zero documentation with this device. Not even a small quick start. I can't even find a default IP. Their website says it is 192.168.1.200 but that does not work. defaulted it and still does not work. Ridiculous that I have to spend a lot of time hunting for the most basic info

Didn’t work, dead out of the box. Bought a replacement and it worked a treat 50% successful rate

Das Gerät hat folgende Aufgaben zu erfüllen.1 ) Kommunikation vom Growatt WR zu einem SDM630 über Ethernet2 ) Kommunikation der WR Schnittstelle (RS485) über Modbus TCP zur Verfügung zustellen (Cacti Aufzeichnung)Das Gerät wurde bei meinem bisherigen Test über PoE mit Spannung versorgt und genehmigt sich ca. 0,5Watt im Betrieb.Die IP der Geräte waren alle verschieden und vermutlich aus diversen Test / Rückläufern. Mit der Software Vircom lässt sich diese entsprechend auslesen und per HTTP/WEB Gui am Gerät selber die Parameter einstellen.Für den Fall 1 werden die Geräte auf Master & Slave gesetzt und konf. und an beiden Seiten kommt das der entsprechende RS485 Anschluss dran (Polung ggf drehen).Der SDM630 hat sich dann recht bald mit dem Telefonzeichen gemeldet, dass die Verbindung läuft.Somit war der Testaufbau für ca. 12h aktivFall 2 wurde entsprechend Modbus TCP am Gerät selber eingestellt inkl. Baud & Co. und Port auf 502 mit dem Programm mbpoll kann dann über "mbpoll -m tcp -a 1 -t 3 -c 125 -1 192.168.0.x" das Gerät (in meinem Fall der Growatt) sauber abgefragt werden.Achtung die Ports für SDM und Daten sind am Growatt 2 verschiedene Anschlüsse.Damit kann ich dann 1*"Cloudstick", 1*Strommesser, 1*Datenabgriff per Modbus TCP praktizieren.Somit sind die Geräte vorläufig weiter zu empfehlen und bei 37Eur (inkl. MWST) sind die Kosten überschaubar. Wer kein PoE braucht oder RS232 Schnittstelle kann vermutlich dann auch bei den 5Eur günstigeren Waveshare anhalten.

Fantástico Con soporte rail din. He tardado 5 mÃn en hacer funcionar EL RS232 a ETHERNET.y 5 mÃn para comunicarme con mi software de labview.

Un serveur Ethernet / RS232/RS485 avec tout plein de fonctionnalités, finis les câbles entre mes maquettes et les serveurs, connectés aux plus près de l'équipement et alimenté en POE par le switch. C'est top !

Works great to allow a rtu based master talk to a tcp based server.Would be nice if the device supported advanced register remapping and datatype mapping, but that is beyond the scope of this device.
