PCI Express x1 Card DeLOCK 89895

The DeLOCK PCI Express x1 Card (89895) adds four external serial RS-232 ports to a PC and supports optional voltage supply on the serial lines. It offers flexible communication parameters and a low-profile form factor for installation in compact systems.

Advantages

This PCI Express card provides four RS-232 ports with selectable 5 V or 12 V voltage outputs on designated pins, a 256‑byte FIFO buffer for stable data flow, and support for multiple data bits and stop bit configurations. The included low profile bracket enables installation in standard and small form‑factor (Mini‑PC) cases.

How to use

Install the card into an available PCI Express x1 slot on the motherboard. Choose the standard or the supplied low profile bracket depending on your case. Connect serial devices to the external RS-232 ports and configure the device voltages if required by selecting the 5 V or 12 V outputs on the specified control pins. Set communication parameters (baud rate, data bits, stop bits, parity) in the operating system or device software to match the connected equipment.

Recommendations

Verify device voltage requirements before enabling the 5 V or 12 V outputs on the RS-232 control pins to prevent damage. Use appropriate drivers provided by the system or manufacturer for stable operation and ensure proper grounding when deploying in industrial environments.
