The Moxa UPort 1130 is an industrial-grade USB-to-serial adapter that enables a connection between modern USB-enabled devices and serial end devices. It is specifically designed for use in environments where a serial interface such as RS-422 or RS-485 is required, but the connected systems do not have an integrated serial interface. The device serves as a bridge between USB and serial communication protocols and is suitable for industrial applications where reliability and stable data transmission are paramount.

Applications

The UPort 1130 is suitable for applications where serial devices such as sensors, controls, measuring instruments, or industrial peripherals must be connected via USB. Typical use cases include integrating legacy devices into modern control systems, communicating with machines in manufacturing technology, or connecting industrial communication modules to PCs or embedded systems. The support for RS-422/485 makes it particularly suitable for long transmission distances and noise-immune environments, as these protocols are robust against interference.

Functions and Features in Detail

The adapter features a serial interface with a male DB9 connector, enabling connection to RS-422/485-compatible devices. Supported baud rates range from 50 to 921.6 kbps, allowing flexible adaptation to different transmission speeds. Data transmission configuration is performed via parameters such as 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 and XON/XOFF, ensuring data integrity at high transmission rates. Power supply is provided through the USB cable at 5 VDC, with a power consumption of 60 mA.

Technology Explained Simply

The UPort 1130 operates as a USB 2.0-compatible converter that transforms the USB interface of a host system (e.g., PC, laptop) into a serial interface. The transmission speed is 12 Mbps, sufficient to support serial data rates up to 921.6 kbps. The serial interface is designed for RS-422/485, enabling bidirectional communication with high noise immunity. Signals include Tx±, Rx±, and GND, with support for both 4-wire and 2-wire modes for RS-485. The use of ABS/polycarbonate as housing material ensures a robust yet lightweight construction.

Compatibility and Accessories

The UPort 1130 is compatible with common operating systems, including Windows (from XP to 11), Linux (kernel 2.4 to 6.x), macOS (from 10.12), and Android (from version 3.1). Driver support also includes virtual machines such as VMware ESXi, Fusion, and Parallels. The delivery includes the UPort 1130, a Mini-DB9F-to-TB adapter, a quick start guide, and a warranty card. The adapter is designed for use in environments with an operating temperature of 0 to 55 °C and humidity of 5–95 % (non-condensing).

Installation and Mounting

Installation is performed by simply connecting the USB end to a USB port on the host system and the DB9 connector to the serial device. Diagnostic LEDs support fault detection and troubleshooting. Configuration of serial parameters is done via the host system’s software or through special configuration tools provided by Moxa. Power is supplied via the USB connection, eliminating the need for an external power source.

Operational Advantages

The UPort 1130 offers a reliable and maintenance-free solution for connecting serial devices to USB-enabled systems. Support for a wide range of serial protocols and baud rates enables flexible integration into existing systems. The robust construction and certifications according to EN 55032/35, CISPR 32, FCC Part 15B, and ESD (contact 4 kV, air 8 kV) ensure a safe and interference-free operating environment. The MTBF is up to 1,949,025 hours according to MIL-HDBK-217F, indicating a long service life. Compatibility with various operating systems and virtual machines significantly expands its application range.

Certifications and Environmental Conditions

The device meets the requirements of standards EN 55032/35, CISPR 32, FCC Part 15B and is certified for ESD protection (contact 4 kV, air 8 kV). It complies with environmental regulations RoHS, CRoHS, and WEEE. The operating temperature ranges from 0 to 55 °C, and the storage temperature ranges from -20 to 70 °C. Humidity is 5–95 %, non-condensing.

Housing and Mechanical Properties

The housing is made of ABS/polycarbonate and has dimensions of 37.5 x 20.5 x 60 mm. The weight is between 65 and 75 g. The mechanical design is intended for use in industrial environments, with materials providing high mechanical stability and resistance to environmental influences.

Software Support

Software support includes operating systems such as Windows (from XP to 11), Linux (kernel 2.4 to 6.x), macOS (from 10.12), and Android (from version 3.1). Support for virtual machines such as VMware ESXi, Fusion, and Parallels enables use in complex IT infrastructures.
