StarTech.com PCI Express Serial Card (2 Port, RS232, 16950 UART, 256-Byte FIFO Cache, Windows and Linux)

The maximum theoretical speed at which a serial communication interface can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. This value represents the upper bound of throughput under optimal conditions and is useful for comparing performance across different serial devices and adapters.

The number of bits used to represent each data unit in a device’s interface or communication channel. It indicates the width of the data path and affects how much information can be transferred per clock cycle. Values are typically integers such as 8, 16, 32, or 64.

The amount of memory allocated for a First In, First Out (FIFO) buffer, expressed in bytes. It indicates how many data units can be stored before processing or transmission occurs.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

List of Linux operating systems that the product can run or support, including specific versions and architectures when relevant. Each value represents a distinct Linux distribution or kernel version supported by the hardware or software.

The vertical dimension of a product’s outer enclosure measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where the overall height of the external case is relevant, including electronics, appliances, furniture and packaged goods.

The linear dimension of a product’s outer case measured in a standard unit such as meters, centimeters or inches. It represents the overall length from one end to the other and is used to compare the size of similar items across categories.

The horizontal dimension of a product’s outer enclosure measured in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.

The type of serial communication interface supported by the product, such as RS‑232, RS‑485, RJ‑45, or SATA. It indicates which physical connectors and protocols are available for data exchange with other devices.

The number of stop bits used in a serial communication interface. Stop bits indicate how many bit periods are transmitted after each data byte to signal the end of that byte and allow the receiver to resynchronize. Common values include 1, 1.5, or 2 stop bits.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.
