Εσωτερικός προσαρμογέας RS-232 DeLOCK 90293

The PCI Express card by Delock expands a PC by one external serial RS-232 port and fits standard and low-profile PC cases. The Internal RS-232 Adapter DeLOCK 90293 uses a SUN2212 chipset, provides a maximum transfer rate of 0.0001152 Gbit/s and a 128 B FIFO buffer. The adapter supports optional device power output of 5 V or 12 V and is compatible with Windows 10, 8.1, 7 and several Windows Server versions.

Advantages

The DeLOCK 90293 offers a compact PCIe solution to add a single external RS-232 port without occupying a motherboard serial header. Its low-profile bracket allows installation in Mini-PCs and small form-factor systems. Built-in FIFO buffering and chipset-level control ensure stable serial communication at typical RS-232 speeds. Selectable 5 V or 12 V power output provides flexibility for different legacy peripherals.

Key specifications

How to use

Install the card into an available PCIe slot on the motherboard. If you use a small form-factor case, replace the full-height bracket with the included low-profile bracket before inserting the card. Secure the card with the case screw, connect the external serial device to the RS-232 port, and, if required by the peripheral, set the output voltage to 5 V or 12 V according to the device specification. Install the appropriate Windows driver if the operating system does not automatically detect the adapter.

Recommendations

Use shielded serial cables for reliable communication in electrically noisy environments, verify peripheral voltage requirements before enabling the 5 V or 12 V output, and ensure you install the driver version matching your Windows release to maintain stability.
