Key Product Features

Technical Specifications

Designed for B2B Integration and Replacement Projects

For commercial customers, selecting an expansion card is not only about port quantity. Model identification, interface type, chipset, certification, warranty, packaging, and supply options are equally important when evaluating a product for distribution or integration.

The W-9900-2S1P clearly identifies these purchasing factors in one model. Its 2-serial-port and 1-parallel-port configuration can help simplify sourcing for projects that require both connection types from a single internal PCI Express card. The defined MOS9900 chip also allows procurement teams to confirm the controller platform before placing orders.

This product can be considered for desktop expansion, equipment integration, replacement-card sourcing, reseller inventories, and other projects where serial and parallel interfaces are required. Buyers should verify host-system slot conditions and end-device interface requirements before final deployment.

OEM, ODM and Packaging Support

The W-9900-2S1P is available for OEM and ODM cooperation, making it suitable for customers who want to develop private-label or customized accessory programs. Packaging can be supplied in a standard color box or customized according to project requirements.

For B2B inquiries, buyers can provide expected order quantity, target market, packaging requirements, branding needs, and other customization details. This information helps make quotation and project evaluation more efficient.
