How to use
Install the DIGITUS DS-33002 into an available PCI slot on a powered-off desktop PC, securing the card with the bracket screw. After booting, install the drivers from the supplied CD or download the appropriate driver for the target operating system. Connect serial devices to the DB9 ports using standard RS-232 cables or the included adapter cable. Configure COM port settings (baud rate, parity, data bits, stop bits and flow control) in the operating system or application to match the connected device’s requirements.
Usage recommendations
For reliable operation, use shielded serial cables for longer runs and set matching baud rate and flow control parameters on both ends. When installing in compact or crowded systems, verify available slot type and clearance for the card bracket. Keep drivers up to date for maximum compatibility and stability, and consult device manuals for specific COM port configuration details.
