The Moxa UPort 1130I is a USB-to-serial converter that connects a serial interface to modern computers lacking an integrated serial port. The device is specifically designed for industrial applications, control systems, and POS systems where reliable and robust data transmission is required. As a member of the UPort 1100 series, it offers high compatibility with various operating systems and supports a maximum transmission rate of 921.6 kbps. Notably, the galvanic isolation of 2 kV makes the device suitable for use in harsh environments with increased electromagnetic interference or voltage surges.

Applications
The UPort 1130I is suitable for applications requiring serial communication over USB, such as industrial automation, machine control, logistics, or retail. Support for RS-422 and RS-485 enables connection to devices using these protocols, such as sensors, printers, or industrial controllers. The galvanic isolation protects the connected device and computer from voltage spikes caused by electrical disturbances or short circuits.

Features and Specifications in Detail
The device features a DB9 male connector for the serial interface and a USB Type-A connector for connection to the computer. It supports RS-422 and RS-485 standards, transmitting signals TxD, RxD, Tx+, Tx-, Rx+, Rx-, and GND. The baud rate can be set between 50 bps and 921.6 kbps, with configurable data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parity (none, even, odd, Space, Mark). Flow control is supported via RTS/CTS, XON/XOFF, or can be disabled. Power is supplied via the USB cable at 5 VDC, with the UPort 1130I consuming 65 mA.

Technology Explained Simply
The 2 kV galvanic isolation electrically separates the serial port from the USB port to prevent interference and damage from voltage spikes. This is particularly important in industrial environments where electrical disturbances are common. The USB interface is compatible with USB 2.0 and conforms to USB 1.0/1.1, ensuring broad compatibility with various computers. The maximum transmission rate of 921.6 kbps enables fast data transfer, sufficient for many industrial applications. Signals are transmitted via a DB9 connector, with specific signals (TxD, RxD, Tx+, Tx-, Rx+, Rx-, GND) defined for the respective protocols (RS-422/485).

Compatibility and Accessories
The UPort 1130I is compatible with Windows (11 to XP, Server 2022 to NT), Linux (kernel 2.4 to 6.x), macOS (10.12 to 10.15), and Android (from 3.1). Virtual machines such as VMware Fusion, ESXi, and Parallels are also supported. Driver support for these systems enables easy integration into existing IT infrastructures. The device is supplied with a mini-DB9F-to-terminal block adapter, allowing flexible connection to terminal blocks. Additionally, a quick start guide and warranty card are included in the delivery scope.

Installation and Mounting
Installation is performed by simply connecting the USB cable to a USB port on the computer and the DB9 connector to the serial device. Drivers are installed automatically, with support for the listed operating systems ensuring smooth setup. The compact design with dimensions 37.5 × 20.5 × 60 mm allows flexible placement, e.g., on a desk or in a control console. The housing is made of ABS + polycarbonate, ensuring a robust and durable construction.

Operational Advantages
The UPort 1130I provides a reliable and low-maintenance solution for connecting serial devices to modern computers. The galvanic isolation enhances safety and extends the device's lifespan, especially in industrial environments. High compatibility with various operating systems and support for virtualization platforms expand its application possibilities. Easy installation and low power consumption of 65 mA make the device an efficient solution for serial communication over USB. The operating temperature range of 0 to 55 °C and storage temperature range of -20 to 70 °C allow use in a wide variety of environments. Certifications according to EN 55032/35, FCC Part 15B, RoHS, CRoHS, and WEEE, along with ESD protection of 4 kV (contact) and 8 kV (air), underscore the product's quality and reliability. The MTBF is 1,949,025 hours according to MIL-HDBK-217F, indicating a high service life.
