LRUA9284-4S1P is a PCIe x1 to 4-port RS232 + 1-port LPT Card designed by Linkreal Co., Ltd. based on CH384P chip. The first serial port of the adapter supports TTL level output, which can meet the requirements of specific equipment or development and debugging. All serial ports support 12V and 5V power supply, and the serial port power supply function can be set by jumping the cap, and PCIe and external power supply can be automatically switched to ensure stable power supply in various scenarios.

The equipment has a wide range of system compatibility, compatible with CPU platforms such as Phytium, Kirin, Zhaoxin, and Hygon, as well as operating systems such as UOS, KOS, and Windows, ensuring stable operation on different platforms. Built-in 8KV ESD protection circuit can effectively resist electrostatic interference and improve the overall stability and reliability of the system. Its design is compact and energy-saving, and it is widely used in industrial control, security monitoring, retail settlement, educational display and large-screen display.
