The UPort 1110 from Moxa is a USB-to-serial converter designed specifically for connecting devices with an RS-232 interface to modern computers that lack an integrated serial port. This device serves as a bridge between USB and serial communication standards, enabling the use of legacy devices, measuring instruments, or point-of-sale systems that feature an RS-232 interface on computers equipped only with USB ports. The converters are compact and designed for mobile applications, making them particularly suitable for environments with limited space or where devices are frequently relocated.

Applications

The UPort 1110 is used in areas where serial communication is required, but the computers in use no longer have a physical RS-232 interface. This includes mobile work environments such as mobile data processing, connecting industrial measuring devices, laboratory instruments, or POS terminals. The converters are designed for use in environments where stable and reliable data transmission over serial connections is necessary, without requiring a complex network infrastructure.

Functions and Equipment in Detail

The converter converts a USB signal into an RS-232 signal, enabling communication between a USB-capable host computer and an RS-232-capable device. The RS-232 interface is a widely used standard for serial data transmission, particularly found in older or specialized devices. The UPort 1110 supports standard transmission parameters typical for RS-232 connections and ensures bidirectional data transmission.

Technology Explained Simply

The technology of the UPort 1110 is based on converting a USB signal into a serial RS-232 signal. This is achieved through an integrated USB controller that receives data from the USB host and converts it into the serial format understood by RS-232 devices. The transmission takes place via a DB9 connector (male), which is connected to the target device. Power supply is provided through the USB cable, eliminating the need for an additional power source. The converters are therefore passive and require no external power supply.

Compatibility and Accessories

The UPort 1110 is compatible with devices featuring an RS-232 interface and can be connected to any USB port that supports the required power supply and data transmission. Compatibility with operating systems is not described in detail, but it is implicitly assumed that standard USB and RS-232 drivers are sufficient to establish communication.

Installation and Mounting

Installation of the UPort 1110 involves simply connecting the USB cable to a free USB port on the computer and then connecting the DB9 plug to the RS-232 port of the target device. No additional tools or installation steps are required. Communication is established via the standard drivers of the operating system, with no special configuration or software installation necessary.

Advantages in Operation

The UPort 1110 enables simple and reliable connection of RS-232 devices to modern computers without requiring additional hardware or complex network interventions. The converters are compact, lightweight, and suitable for mobile use, making them particularly appropriate for mobile applications. Power supply via the USB cable reduces the number of required cables and avoids additional power sources. The use of the RS-232 standard ensures high compatibility with a wide range of devices that support this interface standard.
