Product information

Description

The DIGITUS USB 2.0 to RS232 adapter cable DA-70172 is a 1.8 m interface cable that provides a serial RS232 connection via a USB Type-A port. The cable integrates an FTDI FT232RNL chipset to convert USB signals to a standard DB9 serial interface, enabling connection of legacy and industrial devices such as printers, measurement instruments, routers and other equipment with RS232 ports. The adapter supports USB 2.0 (backward compatible with USB 1.1) and offers full-duplex communication with configurable baud rates, preserving a stable serial link between modern computers and serial devices.

Advantages

The integrated FTDI FT232RNL chipset offers proven USB-to-serial conversion with reliable driver support across major platforms. Gold-plated contacts improve signal quality and resist corrosion while LED status indicators provide visual confirmation of data activity. The cable supports a wide range of voltage output levels for RS232 and retains COM port assignments after reconnection for consistent device addressing. Its 1.8 m length and screw/nut mounting option make it practical for flexible and secure installations.

Suitable for

Connecting legacy serial printers and POS devices to modern PCs
Linking industrial controllers, PLCs and measurement instruments to monitoring systems
Serial console access to routers, switches and embedded devices
Software development and debugging where RS232 serial ports are required

How to use

Connect the USB Type-A plug to an available USB port on your computer and attach the DB9 connector to the serial device. Install drivers if your operating system requires them; Windows, macOS and Linux distributions commonly provide automatic or downloadable FTDI drivers. After installation the adapter appears as a COM (serial) port on the host system; configure the serial client or terminal software to match the device baud rate, data bits, parity and stop bits. Use the screw/nut mounting on the DB9 connector if a fixed mechanical connection is required.

Usage recommendations

For stable operation, select matching serial settings (baud rate and parity) in both host software and the serial device. If automatic driver installation does not occur, download the appropriate FTDI driver for your operating system. Avoid excessive cable bending near the connector ends and secure the DB9 connector with the mounting screws when used in industrial or vibration-prone environments.
