TCP232-306 RS232 RS485 RS422 to Ethernet TCP IP Modbus Gateway Serial Device Server Serial to ethernet converters

Ottima interfaccia per rs485-TCIP che ho utilizzato per convertire il modbus serialle su protocollk tcip e funziona correttamente.

Works well. Drop in replacement for a Newport serial to Ethernet server that died after 25 years. To configure it, you need to have an Ethernet port on your PC and configure the TCP/IP Ethernet to match the device's IP subnet which is 192.68.0.x. The device defaults to address 192.168.0.7. You can change IP settings in config. Once you've done that, you can connect to the device using http://192.168.0.7 and use default userid/pass of admin/admin (the userid/pass isn't in the docs, so I had to download the PC config program to control it, but it would be easier to just use the http server). If you want other PCs to connect to it and use the attached serial port, configure it as a TCP server and set a port number. If you want this device to constantly connect to some other server PC, configure it as a TCP Client and give the remote PC address/port info. Serial port settings are broad. Many devices default to the default of no parity, 1 stop bit, 8 bit data.

Der kleiner Serielle Server ist gut verarbeitet und funktioniert bei mir ohne Probleme. Ideal um nicht smarte projekte smart zu machen.

Tutto perfetto.

It works just like I expect - it has a web interface to set serial port properties. To send or receive serial data, you connect to it via a TCP socket. And, it's reasonably priced. It comes with a 5V, 1A power supply and a DB9 serial cable. It accepts a wide input voltage so it's easy to power. I also like the terminal blocks to make it easy to hook up RS485 or 422 devices without needing to custom wire a D-sub connector. The configuration website is a little hard to decipher because the defaults don't seem to be a functional configuration. I set the "Work Mode" to TCP Server, and then set the "Local Port Number" to the port number, and was able to open a socket and communicate. Supposing you had a modem attached to the serial port, and configured the Local Port Number to 3000: import socket s = socket.socket() s.connect(('192.168.0.7', 3000)) s.send(b'AT\r\n') data = s.recv(1024) # should be b"OK" It has some other operating modes (UDP, etc). There are manuals on the manufacturer's website. I'm planning to use it to speak RS485 to my water heater's data port, so I can track temperature and power usage.
