Pylontech Batteries RJ45 CONSOLE Port for Monitoring will only work on 115200 Baud Rate and must be set EXACTLY as below. Other batteries may differ e.g RJ11 Ports may be 1200 or whichever setting manufacturer of device to be programmed or be monitored recommends.

To Connect from a Windows PC to the Converter ENSURE Port number is correct as below and configured and Device is set to SERVER Mode.

If Connection was successful a Virtual Com Port over Network will be visible in Windows Device Manager as below. If Connection fails please check your firewall settings for the VCOM App, Check Port number correct on Connection and ensure device in Server Mode.

We can now monitor or program e.g Solar Batteries, Inverter, Managed Network Switch, Firewall, PLC, Access Controller etc over a Network connection which provides unlimited distances without the Serial DB9 or RS485 Cable Limitations. Any RS232, RS422 or RS485 Device will work with this device over a network connection.
