RS485-4G Converter.
Up to 128 RS485 devices can be linked at most.
Set the server's IP/port/domain name and other parameter information via RS485.
It can read the local MODBUS ID, device address, RS485 parameters and other parameter information.
Multiple Working Modes available.
J119026 is an RS485-4G converter. It can set or read data from ordinary RS485 meters through the 4G master station.
In theory, any RS485 meter can be used in conjunction with it.
There are no restrictions on the protocol. Generally, a single converter can connect up to 128 RS485 meters in the downlink direction.
