## Long description

The DIGITUS USB 2.0 Serial Adapter DA-70156 provides a serial RS232 interface via a USB 2.0 connection, enabling connection of devices with an RS232 (D-Sub 9) port to modern computers that lack a native COM port. The compact black adapter uses an FTDI FT232RNL chipset and is powered directly from the USB port without a separate power supply.
Advantages
The adapter supports the USB 2.0 standard with backward compatibility to USB 1.1, offers full-duplex communication and configurable data transfer rates from 75 to 128,000 bits per second. It includes remote wake-up and power management features, a true CMOS output with TTL input levels (supporting 5V, 3.3V, 2.8V and 1.8V), and wide operating system compatibility through the FTDI chipset.
Suitable for
Connecting modems, printers and scanners with RS232 interface
Linking industrial equipment and machine controls to PCs
Interfacing sensors, weather stations and PDAs
Using with set-top boxes, consoles and legacy devices that require a COM port

For stable communication, use the adapter with the recommended baud rates for your device and ensure correct parity and flow control settings.
