PCIe x1 to 4-port RS232 + 1-port LPT Card based on CH384P chip.
The LRUA9284-4S1P is a PCIe x1 to 4-port RS232 + 1-port LPT Card designed by Linkreal Co., Ltd. based on the CH384P chip. It provides four independent asynchronous serial ports conforming to the 16C550 standard and one parallel port conforming to IEEE1284 protocol.
The first serial port supports TTL level output, meeting the requirements of specific equipment or development and debugging. All serial ports support 12V and 5V power supply, which can be switched by jumping the cap. 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. 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.
