Description

The Moxa UPort 1250I-G2-T/KC is a 2-port RS-232/422/485 USB-to-serial converter for industrial deployments, connecting two DB9 serial devices to a host over SuperSpeed USB 3.2 Gen 1. This KC certified variant adds 2 kV isolation on the serial ports and a wide -40 to 75°C operating range, suiting factory floors, outdoor cabinets and other demanding environments.

The metal IP20 housing is bus-powered over USB, so no external power supply is needed. It supports baudrates from 50 bps to 921.6 kbps including non-standard rates, automatic data direction control for RS-485, and drivers for Windows, Linux, macOS and Android, including virtual machine environments.

Features

- SuperSpeed USB 3.2 Gen 1 with USB 2.0 backward compatibility
- 2 kV isolation protection on serial ports
- Wide operating temperature range of -40 to 75°C
- Automatic Data Direction Control (ADDC) for RS-485
- Supports non-standard baudrates up to 921.6 kbps
- Drivers for Windows, Linux, macOS and Android, with virtual machine support (VMware, Parallels)
- Metal housing, bus-powered via USB

FAQs

Q: Which serial interfaces does the UPort 1250I-G2-T/KC support?
A: Each of the two DB9 male ports can be configured for RS-232, RS-422 or RS-485 operation.

Q: Does it need an external power supply?
A: No. It is powered from the USB bus at 5 VDC, drawing 400 mA on USB 3 or 240 mA on USB 2.

Q: Can it be connected to a USB 2.0 port?
A: Yes. It is backward compatible with USB 2.0 and USB 1.1 hosts, though the SuperSpeed 5 Gbps rate needs a USB 3.x port.

Q: What does the 2 kV isolation provide?
A: It protects the host computer and connected equipment by electrically isolating the serial ports from the USB side, useful in electrically noisy industrial environments.

Q: Which operating systems are supported?
A: Drivers are available for Windows (including Windows 11 and 10), Linux kernels 4.x to 6.x, macOS and Android 3.1.x and later.

Q: Is it suitable for extreme temperatures?
A: Yes. It is rated for operation from -40 to 75°C, with a metal IP20 housing.
