DIGITUS Serial I/O,2-port, Pci-e Add-On card 2 X DB9 M Slot Bracket + LP Brackets MCS9901 chIPSet

The DIGITUS Serial Interface Card 2-Port PCIe converts a PCI Express slot into two RS232 (DB9) serial ports, enabling connection of serial modems, PDAs, digital cameras, printers, ISDN terminal adapters and other legacy devices. It is based on a native single-chip design (Blech OXPCIe952 chipset) and supports data transfer rates up to 128,000 bps while reducing CPU load compared with conventional serial cards. The card is compliant with the PCI Express base specification 2.0 and provides two male DSUB 9 connectors with UART 16C950 functionality.

Advantages

The PCIe serial card offers two reliable RS232 ports in a single low-profile card, supports high data rates up to 128,000 bps and follows PCI Express 2.0 standards for broad compatibility. The native single-chip design lowers CPU overhead, and the onboard UART 16C950 ensures stable serial communication with legacy equipment.

Suitable for

• Connecting serial modems and ISDN terminal adapters
• Integrating legacy industrial equipment and controllers
• Attaching POS devices, receipt printers and barcode scanners
• Supporting serial PDAs, older digital cameras and measurement instruments

How to use

Power off the computer and insert the card into an available PCI Express slot, securing it to the case. Connect serial devices to the two DB9 ports using standard RS232 cables. After powering on the system, install any required drivers provided by the operating system or the manufacturer. Verify port assignment in the system device manager and configure baud rate and serial parameters (parity, data bits, stop bits) in the application that will access the ports.

Recommendations

For stable operation, use shielded RS232 cables for connections in electrically noisy environments and match serial settings (baud rate, parity, data bits, stop bits) between the card and the connected devices. Ensure drivers are up to date for your operating system and, if used in industrial systems, fit the card in a low-profile or standard bracket according to your chassis.
