The Startech.com ICUSB232DB25 is a USB to Serial RS232 adapter cable with integrated DB9/DB25 connector, enabling the connection of serial RS232 devices to modern computers via a USB port. The device functions as a cable adapter and emulates a serial port, allowing older peripheral devices to be connected to modern systems. The compact, grey cable, measuring 0.9 m in length, is designed for use in IT environments, industrial applications, laboratory settings, and logistics systems where connection to serial devices is required.

Applications
This adapter is ideal for integrating serial devices into modern IT systems. Applications include connecting barcode scanners, receipt printers, industrial sensors, PLC controls, medical devices, oscilloscopes, scales, and ODB/ODBII sensor adapters in the automotive industry. It is particularly used in server rooms, industrial automation, point-of-sale systems (POS), and AV installations where compatibility between new computers and legacy hardware must be ensured.

Features and Equipment in Detail
The device features a USB Type-A connector at one end and a DB-9 connector at the other, with an additional DB-9 to DB-25 adapter included in the package to connect 25-pin serial devices. The cable length is 0.9 m, allowing direct connection between the computer and the serial device without requiring additional extension cables. Cable securing is achieved via screw nuts on the serial connector to ensure a stable connection.

Technology Explained Simply
The adapter is based on the Prolific PL2303GC chipset, which enables conversion of USB signals into RS232 serial signals. This chipset supports a maximum baud rate of 230.4 kbit/s and allows configuration of various serial parameters such as data bits (4 to 8), parity modes (None, Even, Odd, Mark, Space), and stop bits (1, 1.5, 2). The FIFO buffer size is 512 bytes, ensuring efficient data transfer. The device is USB 2.0 Full-Speed compatible and supports Plug-and-Play and Hot-Swap, allowing it to be connected without restarting the system. Power is supplied via the USB cable; no external power source is required.

Compatibility and Accessories
The adapter is compatible with a wide range of operating systems, including Windows 7 to Windows 11, Windows Server 2003 to 2022, macOS (from version 10.6 to 13.0), and Linux (from version 2.4.x, including LTS versions). The drivers are Microsoft WHQL-certified, ensuring stable and reliable performance on Windows systems. It can also be used in embedded systems such as Windows Mobile, CE, and POS Ready 2009. The package includes the USB/RS232 adapter cable, the DB-9 to DB-25 adapter, a driver CD, and an instruction manual.

Installation and Mounting
Installation is performed by simply connecting the USB connector to an available USB port on the computer and the DB-9 or DB-25 connector to the serial device. Most systems automatically detect the device and install the necessary drivers. If needed, installation can be supported using the software provided on the included CD. The connection is stable and requires no additional tools or configuration steps.

Operational Advantages
The adapter offers a cost-effective solution for bridging modern computers with older serial peripherals. The integrated cable length of 0.9 m and the included DB-9 to DB-25 adapter card increase flexibility when connecting devices. Support for Plug-and-Play and Hot-Swap enables quick and uncomplicated installation. The use of the Prolific chipset ensures reliable and high-performance data transfer. Compatibility with a wide range of operating systems and support for various serial parameters make the adapter a universally applicable solution.
