Moxa UPort 1150I , RS-232/422/485 with isolation content_copy

The Moxa UPort 1150I is a USB-to-serial converter, specifically developed for industrial use. It serves to connect modern computers with older serial devices that feature RS-232, RS-422, or RS-485 interfaces. This is particularly relevant in automation technology, measurement technology, and the POS sector, where serial communication is often still required, but modern systems no longer have integrated COM ports. The converter enables reliable data transmission with a maximum baud rate of 921.6 kbps and supports various serial protocols, including RS-232, RS-422, and RS-485. Galvanic isolation with an isolation strength of 2 kV protects against voltage spikes and potential differences, enhancing stability and safety in industrial environments.

Applications

The UPort 1150I is designed for applications requiring a robust and secure serial interface. Typical use cases include industrial automation, where it facilitates communication with controllers, sensors, or machines. It is also suitable for measurement technology, for data acquisition from measuring instruments, or in the POS sector, where legacy cash registers or peripheral devices must be connected to modern computers. Support for various operating systems, including Windows, Linux, macOS, and Android, makes it highly flexible.

Functions and Features in Detail

The converter features a male DB9 connector and supports all common serial signals, including TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND for RS-232, as well as Tx±, Rx±, and GND for RS-422 and RS-485. Configuration is flexible: data bits can be set to 5, 6, 7, or 8, stop bits to 1, 1.5, or 2, and parity options include None, Even, Odd, Space, and Mark. Flow control methods such as RTS/CTS and XON/XOFF are also supported. The USB interface is USB 2.0 compatible and operates at a speed of 12 Mbps, with compatibility also ensured for USB 1.0/1.1.

Technology Explained Simply

Galvanic isolation (isolation) at 2 kV protects connected devices from electrical disturbances caused by differing ground potentials or voltage spikes. This is especially important in industrial environments, where high electrical loads and interference sources are common. Power supply is via the USB connection (5 VDC), with the UPort 1150I consuming 260 mA. The housing is made of metal, providing better mechanical stability and EMI shielding. Dimensions are 52 x 80 x 22 mm, and the device weighs 75 g.

Compatibility and Accessories

The UPort 1150I is compatible with a wide range of operating systems, including Windows 11 to XP, Server 2000 to 2022, Linux kernel 2.4 to 6.x, macOS 10.12 to 10.15, and Android from version 3.1. Virtualization environments such as VMware ESXi/Fusion and Parallels are also supported. The device is designed for operating temperatures from 0 to 55 °C and can be operated at a humidity level of 5 to 95 % (non-condensing). Certifications include EMC (EN 55032/35), EMI (CISPR 32, FCC Part 15B Class 1), ESD (contact 4 kV / air 8 kV), safety standards (UL 60950-1), and environmental standards (RoHS, CRoHS, WEEE). The MTBF is 1,949,025 hours according to MIL-HDBK-217F.

Installation and Mounting

Installation is performed by connecting the USB Type-B plug to a USB port on the computer and connecting the DB9 connector to the serial device. The delivery includes a mini-DB9F-to-terminal block adapter, which simplifies wiring, especially for devices with terminal connections. A USB cable is also included in the delivery. The quick start guide and warranty card support setup.

Operational Advantages

The UPort 1150I offers a reliable, high-performance, and safety-oriented interface for industrial applications. Galvanic isolation increases operational safety, the high baud rate enables fast data transmission, and broad operating system support ensures flexibility. The metal housing and robust construction ensure long service life even under harsh operating conditions.
