EXSYS EX-43362 Placa controladora serial PCI Express 2 portas RS-232

PCI Express serial controller card with dual RS-232 ports delivers reliable high-speed connectivity for industrial and legacy devices. The EX-43362 leverages the ASIX AX99100 chipset to provide two independent 921.6 Kbps serial channels over a single PCIe x1 lane, ensuring smooth integration with modern systems while maintaining compatibility with existing serial equipment.

Advantages

This card offers native PCI Express connectivity, eliminating the need for USB-to-serial adapters and their associated latency. Each port features a 256-byte FIFO buffer to reduce CPU overhead during sustained data transfer. The included low-profile bracket allows installation in slim desktops and 2U rackmount chassis, while 15KV ESD protection safeguards against electrical surges. Hardware and software flow control options provide flexible handshaking for diverse peripherals.
