Microconnect MC-PCIE-MCS2S Interface Cards/Adapters Internal Serial

The Microconnect MC-PCIE-MCS2S is a PCI Express expansion card that provides two external serial ports (RS-232) and one external parallel port. It uses the MCS9901 chipset and fits into a standard PCIe slot to add legacy device connectivity to desktop PCs. The card is supplied with a standard profile bracket already mounted and includes an extra low-profile bracket for compact or small-form-factor systems.

Advantages

The card delivers reliable serial and parallel connectivity for peripherals such as scanners, printers and mice. Its PCIe host interface ensures compatibility with modern motherboards while the compact dimensions (175 mm x 130 mm x 34 mm) and light weight (0.11 kg) make it suitable for a range of desktop and compact PC enclosures. Inclusion of both standard and low-profile brackets simplifies installation in different chassis types.

Suitable for

• Connecting serial devices (RS-232) such as barcode scanners and industrial equipment
• Adding a parallel port for older printers and legacy peripherals
• Upgrading desktop or small-form-factor PCs that require additional I/O ports
