Tarjeta de interfaz DeLOCK 89918

The DeLOCK 89918 is an internal PCIe interface card that adds two external RS-232 serial ports to a PC. Based on the WCH CH382L chipset, the card extends serial communication capabilities for connecting scanners, protocol converters, IoT devices and other RS-232 peripherals. A low-profile bracket is included for installation in Mini-PCs.

Advantages

The card provides two reliable external RS-232 ports via a PCIe host interface and supports flexible serial frame formats with data bits of 5, 6, 7 or 8 and stop bits of 1 or 2. It is compatible with common Windows versions (Windows 10, 8.1 and 7) and includes a low-profile bracket for compact systems.

Suitable for

• Connecting barcode scanners and measurement instruments
• Interfacing with protocol converters and industrial controllers
• Extending serial ports for legacy peripherals in desktop and Mini-PC systems
• Integrating RS-232 IoT devices into a PC-based system

How to use

Power off the PC and insert the card into an available PCIe slot on the motherboard. Secure the card with the full-height or included low-profile bracket depending on your case form factor. Boot the system, install the appropriate driver for the WCH CH382L chipset on a supported Windows version, and connect external RS-232 devices to the serial ports using standard serial cables. Configure port parameters (baud rate, data bits, parity, stop bits) in your operating system or application to match the connected device.

Recommendations

For stable communication, use shielded serial cables and set matching serial parameters on both the PC and the connected device. Install the latest chipset driver from the manufacturer for best compatibility with Windows 10, 8.1 and 7.
