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 protocoland 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

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.
