Industrial Wireless Gateway

The PUSR USR-W660S is a dual-band WiFi 6 access point built for industrial edge computing. It bridges CAN, CAN FD, RS232 and RS485 field buses to five Gigabit Ethernet ports and wireless networks. Engineers use it to connect legacy automation equipment to modern IP infrastructure without a separate switch.

Interface and Bandwidth Limits

Five Gigabit Ethernet ports share a single 1 Gbps uplink through the WAN/LAN port, so aggregate wired throughput cannot exceed that link. Dual-band Wi-Fi 6 operates on 2.4 and 5.8 GHz radios, but total wireless capacity is still bound by the same Gigabit backhaul. CAN and serial traffic must fit within the same pipe.

Pre-Installation Checklist

Verify that your CAN bus uses standard or FD framing compatible with the built-in USR-CAN528 module. Confirm the serial devices require RS232 or RS485 levels matching the gateway pin-out. Ensure the mounting location can accept a Black enclosure powered from a supply that meets the unspecified wide voltage range.

Questions about this item

Should I pick the WAN/LAN port or one of the four LAN ports for my uplink?

The single WAN/LAN port can serve as uplink or extra LAN; the four dedicated LAN ports connect downstream devices directly without an external switch.

What does Wi-Fi 6 give me on this gateway in a live network?

Dual-band 2.4 GHz and 5.8 GHz Wi-Fi 6 provides fast switching, seamless roaming and low-latency wireless links for CAN, RS-232 and RS-485 data streams.

How does the CAN interface connect to Ethernet and Wi-Fi?

The built-in CAN/CAN FD gateway (USR-CAN528) converts CAN bus frames to Ethernet or Wi-Fi 6 packets for edge computing and data acquisition.
