Serial Device Server
USR IoT · 8-port
An eight-port serial device server from USR IoT: transparent transfer between TCP/UDP packets and 8 × RS485 ports, with a built-in Modbus gateway. It brings serial meters, PLCs and energy meters onto Ethernet for MY-IIOT and host systems.
Core functions
- 8 × RS485Eight RS485 ports in one unit for concentrated connection of field serial devices.
- Transparent transferBidirectional transparent transfer between TCP/UDP packets and serial data, leaving the existing serial protocol untouched.
- Built-in Modbus gatewayModbus protocol conversion for straightforward integration with host systems.
- Wide-range inputDC 9.0 V – 36.0 V input drawing 120 mA at 12 V, tolerant of site power conditions.
- Edge computing and secure transportM7 core with the eight ports working independently; supports edge computing, MQTT and SSL-encrypted transport.

Typical applications
Where serial device servers are used most: bringing RS485 devices onto Ethernet for host systems or MY-IIOT.
Retrofitting legacy serial equipment
Older machines, meters and controllers with only an RS485 port join Ethernet without replacing the equipment.
Modbus devices into host systems
The built-in Modbus gateway converts the serial side to Ethernet protocols for SCADA, MES and MY-IIOT.
Consolidating multiple serial links
Eight ports working independently let one unit concentrate several serial links, cutting field cabling and cabinet space.
