Industrial PCIe serial card with four RS485/RS422 ports supporting up to 921.6 kbps bandwidth.
Connecting legacy industrial equipment to modern servers often requires reliable, high-density serial interfaces that standard motherboards lack. The LRUA9254-485 PCIe serial card solves this by providing four independent RS485/RS422 ports in a compact low-profile form factor, ensuring seamless integration into miniature computers and mainframes.
Powered by the XR17V354 I/O controller, each port delivers up to 921.6 kbps bandwidth with 128-byte FIFO buffers. This hardware-level flow control eliminates data loss during high-throughput industrial communication, while the 3.3V power supply ensures compatibility with diverse PCIe slots without additional power connectors.
Ideal for factory automation, POS systems, and telecom infrastructure, this card supports Windows and Linux operating systems. Included HDB44M to 4*DB9M cables and interchangeable brackets simplify deployment. Choose the LRUA9254-485 for robust, multi-port serial connectivity in space-constrained industrial environments.
Features four independent RS485/RS422 ports, each supporting bandwidths up to 921.6 kbps for efficient industrial data transmission.
Equipped with 128-byte FIFO and hardware/software flow control (RTS/CTS, XON/XOFF) to ensure data integrity.
Low-profile form factor (87mm*65mm) with interchangeable brackets fits miniature computers and standard mainframes.
Supports major operating systems including Windows and Linux, ensuring easy integration into existing infrastructures.
Internal LED indicators and software management tools facilitate quick troubleshooting and status monitoring.
