MicroConnect MC-PCIE-MCS2S PCI Express 2-Port Serial RS-232 Adapter (ASIX MCS9901)

The MicroConnect MC-PCIE-MCS2S PCIe 2-Port Serial RS-232 Adapter (ASIX MCS9901) is an internal expansion card that adds legacy serial ports to desktop computers. The card converts a PCI Express slot into two active serial ports for data exchange with peripheral hardware. It is designed for industrial and commercial environments that require interfacing older equipment, such as barcode scanners or controllers, with modern systems. This card provides the dedicated serial connection often missing from contemporary motherboards, allowing for the continued use of specialized equipment without the need for external converters.

Installation requires one available PCIe slot, which supplies the card with power and data connectivity. The ports are accessible from the rear I/O panel, where they can be used to connect automated machinery, point-of-sale terminals, or laboratory instruments. The card supports applications that require direct hardware addressing to maintain communication integrity. It features a standard mounting bracket to secure the card to the chassis, ensuring stability when connecting or removing devices.

• ASIX MCS9901 chipset: handles serial processing for stable communication with legacy peripherals.
• Two independent serial ports: support the simultaneous operation of two devices via a single expansion slot.
• Standard DB-9 connectors: provide a secure interface for industrial serial cabling.
• Dimensions (175 mm x 130 mm x 34 mm): compatible with standard desktop computer housings.
• Weight (110 g): lightweight construction reduces physical strain on the motherboard slot.
• RS-232 communication standard: provides the voltage and signaling required for legacy hardware.
