5. Setup

5.1. Driver Installation

The Digitus DA-70156 adapter utilizes the FTDI / FT232RL chipset. For most modern operating systems (Windows 8/8.1/10/11), drivers are often installed automatically when the device is connected to an active internet connection. For older Windows versions (7, Vista, XP), Mac OS X, or Linux, manual driver installation may be required.

1. Automatic Installation (Windows 8/8.1/10/11): Connect the adapter to an available USB port on your computer. If connected to the internet, the operating system should automatically detect and install the necessary drivers.
2. Manual Installation: If automatic installation fails or for other operating systems, insert the provided Product Support CD-ROM. Follow the on-screen instructions to install the FTDI drivers. Alternatively, the latest drivers can be downloaded from the official FTDI website.
3. After installation, verify the adapter is recognized in your device manager (Windows) or system information (Mac/Linux) as a USB Serial Port.

5.2. Physical Connection

1. Connect the USB-A end of the Digitus DA-70156 adapter to an available USB 2.0 port on your computer. You may use the included USB extension cable for added reach.
2. Connect your RS232 serial device (e.g., modem, printer, industrial equipment) to the DB9 male serial connector on the adapter. Ensure the connection is secure by tightening the screws on the DB9 connector.

6. Operating Instructions

6.1. Connecting Serial Devices

Once the drivers are installed and the adapter is physically connected, your computer will recognize the serial port. You can then use software applications designed for serial communication to interact with your connected devices. Examples of compatible devices include:

• Weather stations
• Sensors
• Motor controls
• Set-top boxes
• Gaming consoles
• Modems
• Printers

6.2. Data Transfer

The adapter supports data transfer rates of 1Mbps and higher, ensuring efficient communication with your serial devices. Configure your serial communication software with the appropriate baud rate, data bits, parity, and stop bits to match your connected device's requirements.

7. Troubleshooting

• Device Not Recognized: Ensure the adapter is firmly connected to a working USB port. Reinstall drivers from the CD-ROM or the FTDI website. Try a different USB port or computer.
• Communication Errors: Verify that the serial communication settings (baud rate, data bits, parity, stop bits) in your software match those of your connected serial device. Check the physical connection of the DB9 cable.
• Slow Data Transfer: Ensure you are using a USB 2.0 compatible port for optimal speed. Check for conflicting drivers or background applications consuming system resources.
• No Power: The adapter draws power directly from the USB port. Ensure the USB port is functional.

8. Maintenance

• Clean the adapter and cables with a soft, dry cloth. Avoid liquid cleaners.
• Store the adapter in a cool, dry place when not in use.
