USR-DR404
RS485 to Wi-Fi/Ethernet Converter
USR-DR404 is a device that can realize data communication between RS485 and Ethernet/Wi-Fi. Through this device, the communication between the on-site serial device and the remote SCADA system can be realized. It integrates a wealth of network protocols like MQTT, TCP, UDP etc. and supports a variety of networking methods, suitable for various scenarios
Multiple Networking Options
The USR-DR404 provides a wealth of networking methods to meet customer networking needs.
- AP mode: Allow network devices to access USR-DR404 via Wi-Fi or Ethernet.
- STA mode: USR-DR404 as a network device accesses other networks via Wi-Fi.
- AP+STA mode: Work in AP and STA mode simultaneously.
- Bridge mode: The device connected to the Ethernet port of DR404 is equivalent to directly connecting to the upper-level network, and the DR404 is equivalent to being transparent.
- Router mode: The device connected to the Ethernet port of DR404 will be assigned an IP by the DR404
Data Transmission Encryption
- Supports SSLTLS encryption in TCP cient, HTTP client and MQTT operation modes.
- Supports two-way certificates authentication.
Transparent Transmission Mode
Data is transmitted transparently between RS485 and Wi-Fi / Ethernet via TCP/UDP/HTTP Protocol, enabling data transfer between serial port device and network device
Serial Command Mode
In this mode, USR-DR404 needs work as UDP Client or TCP Client, it allows users to send serial data to different servers. Data, server IP and port information should be included in the data packet sent by the serial device.
Addtional Features
- Modbus Gateway: Modbus RTU/TCP protocol conversion and multi-host Modbus polling.
- Heartbeat Packet Function: Remote server can detect abnormal disconnection from the client using this feature.
- Registration Packet Funciton: The server can identify different clients by usingregistration packets.
- Websocket Function: It can realize the real-time interaction between the serial device connected to DR404 and the web page on PC.
Industrial-Grade Design, High Reliability
- EFT Protection: Level 3, protect device against damage caused by instantaneous current interference in circuit, such as lightning stroke, power switch, etc.
- ESD Protection: Level 4, prevent electrostatic damage equipment, such as dust electrostatic, electric arc environment etc.
- Surge Protection: Level 3.
- Watchdog: Hardware & software dual watchdog to ensure stable operation without downtime.
