Fundamental Function
Bidirectional Transparent transmission
between RS485 and Wi-Fi / Ethernet
Function Structure
Work Mode
Transparent Transmission Mode
Data is transmitted transparently between serial port and
Wi-Fi / Ethernet via DR404, enabling data transfer
between serial port device and network device
Serial Command Mode
The user sends data to the server according to the protocol
and can send data to different servers without restarting.
httpsD Client Mode
After the user completes the https header with an AT instruction or
web page setup, DR404 can pass data to or from the https server.
AT Command Mode
Users can query the current status of DR404
or set relevant parameters by sending AT instructions
Features
Modbus Gateways
Mode of transferring data
between Modbus TCP and Modbus RTU.
Socket Distribution
In transparent transmission mode, the serial device
can send data to the specified Socket connection.
Network data for each Socket are sent to
the serial device via the serial port.
Quick Networking Protocol
USR-LINK
Mobile phone connect to the AP of DR404, you can directly
set the specified AP to which DR404 connects by querying
surrounding AP’s SSID list through USR-LINK, which is
convenient and fast. You can quickly connect to the Internet
without operating DR404.
Custom Registration Package,
Heartbeat Package
The registry package is used for easy device
identification from the server.
