The Moxa UPort 1130 is a 1-port USB-to-serial converter designed specifically for RS-422/485 connections. It’s the right pick when your world is mostly RS-485 networks (or RS-422 links) and you want a purpose-built adapter for commissioning, configuration, and field troubleshooting.

Why We Love This Product

• Purpose-built for RS-422/485—ideal for industrial fieldbus-style serial networks
• Reliable way to connect modern USB-only laptops to RS-485 devices
• Great “daily driver” for technicians working on RS-485-heavy sites

How Our Customers Use It

• Commissioning and servicing RS-485 devices like meters, drives, and controllers
• Temporary laptop access to RS-422/485 links for diagnostics and setup
• Configuration work during upgrades and brownfield maintenance visits

Choosing Tips

• Choose UPort 1130 when you mainly need RS-422/485 (especially RS-485 multi-drop)
• If you need RS-232 as well, choose a multi-standard converter like UPort 1150
• If your devices are RS-232 only, a dedicated RS-232 USB converter is the simpler choice
