## Summary description

DIGITUS USB 2.0 to RS232 adapter cable (DA-70170) provides a bridge between USB Type-A ports and RS232 serial DB9 devices. The 1.8 m transparent cable integrates an FTDI chipset for reliable serial communication and driver support. Ideal for connecting legacy serial equipment, industrial controllers, POS terminals and modem devices to modern PCs and laptops.

## Long description

DIGITUS USB 2.0 to RS232 adapter cable DA-70170 is a combined cable-and-adapter solution that connects USB Type-A ports to RS232 DB9 devices. The 1.8 m transparent cable integrates an FTDI (FT232RNL) chipset that converts USB signals to serial RS232 levels and provides broad driver support and reliable full-duplex serial communication. The cable supplies real RS232 output voltage options and includes gold-plated contacts and a secure screw fastening for robust connections to legacy equipment and industrial peripherals.
Advantages
The integrated FTDI chipset ensures stable signal conversion and automatic driver recognition on many operating systems, which reduces installation effort. Gold-plated contacts improve conductivity and corrosion resistance while full-duplex operation supports simultaneous send and receive. The single-cable design eliminates the need for separate adapters and the 1.8 m length offers flexible placement of connected devices.
Suitable for
Connecting legacy RS232 modems and serial printers to modern PCs and laptops
Industrial controllers and PLCs requiring a DB9 serial interface
Point-of-sale (POS) terminals, measuring instruments and lab equipment with RS232 ports
Configuration and maintenance of routers, switches and other network devices with serial consoles
Embedded systems development and debugging that require serial communication

How to use
Plug the USB Type-A end into a free USB 2.0 (or USB 3.0) port on the host computer and connect the DB9 plug to the serial device. Allow the operating system to install drivers automatically or install the FTDI drivers if required for your OS version. Configure the serial port parameters (baud rate, parity, data bits, stop bits) in the host application or terminal software to match the connected device. Use the screw fastening to secure the DB9 connector to prevent accidental disconnection.
Usage recommendations
For reliable operation, match the cable data rate and serial parameters to the peripheral device settings, ensure firm screw connections on the DB9 plug, and keep the cable routed away from high-voltage or noisy power lines. When using on battery-powered systems, verify power management and remote wake-up settings if required by the connected device.
