This PCIe to RS232 serial adapter card adds eight DB9 serial ports to a desktop computer via a PCIe expansion slot. It is designed for users who need to connect legacy serial devices such as printers, scanners, industrial controls, and medical equipment. The card uses a Systembase SB16C1058PCI chipset with a 16C1050 UART, offering high-speed communication up to 921.6Kbps per port. It also includes a 256-byte FIFO buffer for efficient data transfer and supports various parity modes and data bit configurations.
The card features a low-profile design that fits into small form factor cases, making it suitable for compact desktops and servers. It comes with two low-profile brackets for PCIe 1x slots and includes optional full-profile brackets for compatibility with larger cases. The card provides configurable power options on pin 9, allowing users to choose between 12V/5V or no power delivery. This flexibility ensures compatibility with a wide range of serial devices that may have different power requirements.
Installation is straightforward, with the card pre-configured for low-profile installation and including two breakout cables that provide four DB9 connectors each. These cables help connect multiple serial peripherals without the need for additional adapters. The card is fully compliant with PCIe Base Specifications Revision 1.0a/1.1 and supports Windows operating systems from XP up to the latest versions, as well as Windows Server from 2003 onwards. However, it is not compatible with macOS or Linux systems.
The card is ideal for use in environments such as point-of-sale terminals, factory automation, scientific instrumentation, and medical equipment where reliable serial communication is essential. Its robust design includes protection against electrostatic discharge (ESD) up to 15kV, ensuring durability in industrial settings. The inclusion of hex nuts allows for secure mounting of DB9 connectors using either screws or nuts, enhancing stability during use.
