Description

The Moxa UPort 1650-8-G2-T is an industrial 8-port USB to serial converter that connects up to eight RS-232/422/485 serial devices to a computer through a single USB 3.2 Gen 1 port. Built in a rugged metal housing with a wide -40 to 75°C operating temperature range, it suits factory floors, outdoor cabinets and other harsh environments. This non-isolated model delivers 8 software-selectable serial ports on DB9 male connectors.

Each port supports baudrates from 50 bps to 921.6 kbps with a 512-byte FIFO, and RS-485 operation uses Automatic Data Direction Control (ADDC). The converter can be powered from the USB bus or from a 12 to 48 VDC external adaptor, and drivers are available for Windows, Linux, macOS and the Android API, including virtual machine and Arm-based Linux platforms.
