The Moxa UPort 1150 is a reliable USB-to-serial converter designed for technicians and engineers who still need to connect modern laptops to legacy serial equipment. With support for RS-232/422/485 on a single port, it’s a flexible “one adaptor covers most jobs” option for commissioning, maintenance, and field troubleshooting.

Why We Love This Product

• One adapter supports RS-232, RS-422, and RS-485—ideal for mixed environments
• Simple way to keep older serial devices accessible from modern USB-only laptops
• Industrial-focused build—built for frequent plug/unplug use in the field
• Great “toolkit standard” when you don’t know what serial interface you’ll meet onsite

How Our Customers Use It

• Commissioning PLCs, RTUs, meters, drives, and legacy controllers via serial
• Field servicing and diagnostics where only a laptop + USB port is available
• Temporary serial access for upgrades, cutovers, and troubleshooting sessions
• Bridging USB to RS-485 networks for configuration and testing workflows

Choosing Tips

• Choose UPort 1150 when you need maximum flexibility (RS-232/422/485) from one adapter
• If you only ever use RS-232, a dedicated RS-232 USB converter is often the simpler pick
• If your job is mostly RS-422/485, consider a dedicated RS-422/485 USB converter for a more “purpose-built” setup
