  • Qualcomm quad-core at 1.2 GHz drives sub-100 ms roaming for mobile robots
  • Seven networking modes including AP+STA and STA+WAN fit complex topologies
  • RS232 plus RS485 with dual Gigabit RJ45 ports connect legacy and Ethernet devices
  • MQTT SSL, Modbus gateway and heartbeat packets secure industrial data streams

Industrial Serial Gateway

The PUSR USR-W660 converts RS232 and RS485 signals to dual-band WiFi6 or wired Ethernet, giving legacy equipment a modern network path. A Qualcomm quad-core processor running at 1.2 GHz handles protocol translation for Modbus RTU/TCP, transparent MQTT, TCP, UDP and HTTP streams. Two Gigabit RJ45 ports provide redundant or segmented LAN connections while the radio operates on 2.4 and 5.8 GHz bands under 802.11 b/g/n/ac/ax.

Mobile Automation Fit

AGV and robot operators gain fast roaming under 100 ms, so moving units stay connected across multiple access points without manual reconfiguration. Fixed installations that only need a simple point-to-point link or lack serial interfaces will find the feature set excessive and the configuration overhead unnecessary.

Roaming Switch Time

The sub-100 ms handover between access points is the decisive spec for any mobile deployment; if the application stays stationary, a simpler converter without roaming support will cost less and integrate faster.

Questions about this item

Does the USR-W660 need a DIN-rail kit or can it sit on a bench?

The unit weighs .85 kg and is built for industrial mounting; check the enclosure for integrated DIN-rail clips or screw holes before deciding on a separate bracket.

Which serial port do I wire first, RS232 or RS485, and what baud rate is typical?

Both 232 and 485 ports are active simultaneously; configure the matching baud rate in the web interface after powering the device via the 1.2 GHz Qualcomm processor.

Will the dual-band 2.4 and 5.8 GHz radios need firmware updates to keep roaming under 100 ms?

Firmware upgrades are applied through the web UI or TFTP; keeping the Qualcomm driver current maintains the fast roaming hand-off and Modbus gateway stability.
