Industrial WIFI Serial Converter

The UOTEK UT-9061 bridges RS-232, RS-485 and RS-422 devices to an 802.11 b/g/n wireless network. It operates as an indoor industrial access point with STA, AP and AP+STA modes for flexible deployment. Configuration is handled through a web interface or AT+ instruction set. Surge and lightning protection on every serial and power line hardens the link in harsh environments.

For Legacy Equipment Integration

Engineers connecting PLCs, meters or sensors to modern WIFI infrastructure will find the three serial interfaces and wide 9-30 VDC supply range convenient. The unit is not suited for applications that demand 802.11ac or ax throughput, nor for outdoor installations without additional enclosure. Buyers needing Power-over-Ethernet or fibre uplink should look elsewhere.

Throughput and Environmental Headroom

Serial data rates from 300 to 115,200 bps are supported in asynchronous half-duplex or full-duplex modes. The converter operates reliably from -40 to +85 °C, making it viable for unheated cabinets or factory floors. Bandwidth is limited by the 802.11n radio, so high-volume streaming or large file transfers will saturate the link. Antenna impedance is 50 ohms for standard external antennas.

Questions about this item

Do I need a 9–30 V DC power supply to run the UT-9061?

Yes, the adapter requires an external 9–30 V DC source drawing about 200 mA at 9 V.

Will the UT-9061 protect my legacy RS-485 gear from surges?

Each RS-485/422 line has 3 kA lightning protection, and the RS-232 port includes 600 W surge protection.

How can I confirm the UT-9061 is linked to my Wi-Fi network after setup?

The device sends heartbeat signals and a Wi-Fi connected instruction that can be monitored through the web interface.
