8 / 16-Channel RS485 Serial Device Server

The USR‑N780/N716 is a high‑performance, isolated 8/16 port RS485 edge serial server running on Linux, launched by PUSR. It comes with an industrial‑grade RK3506J chip, featuring a tri‑core Cortex‑A7+ Cortex‑A0 setup, with a max frequency of up to 1.2GHz. It also has the built‑in WukongEdge edge computing engine, which allows you to easily collect data, do edge computing, and send it to the cloud with simple configuration. This series supports 8/16 RS485 ports, 1 CANFD port (compatible with CAN), and 2 100M Ethernet ports. It supports common industry protocol conversions like ModbusRTU/TCP, DL645, IEC104, HJ212, SL651, and can connect to major cloud platforms via MQTT/TLS.

Key Features

This is an all‑in‑one high performance industrial gateway that supports RS485 to Ethernet, edge computing, and various protocol conversions, making it suitable for all sorts of scenarios.

Multiple Serial Ports Work Independently without Interference

The 8/16 RS485 ports are independent. Each serial port supports creating 2 Sockets and can be configured with different baud rates, data bits, parity bits, packet mechanisms, etc.

Powerful Edge Computing Capability

Built-in wukongedge engine for easy configuration and rapid deployment; Supports large-scale data acquisition and multiple reporting methods for diverse application scenarios.

WukongEdge Engine 

This product comes with the WukongEdge edge engine—designed for edge‑cloud collaboration. It combines data access, edge computing, and multi‑channel forwarding all in one, using local storage to cover for network issues, so industrial site data is "calculated accurately, transmitted reliably, and received in abundance."

One Gateway for All Scenarios, Comprehensive Protocol Conversion

Supports protocols for power utilities, environmental monitoring, water management, building automation and industrial PLC systems, and more industry protocols are continuously being added.
