The Sealevel 5104 PCI interface card delivers powerful synchronous serial communication in a compact MD1 low-profile form factor. Equipped with one versatile port, the adapter supports multiple electrical standards—RS-232, RS-422, RS-485, RS-530, RS-530A, and V.35—making it a flexible solution for telecom, military, industrial automation, and protocol-driven environments.
At the heart of the 5104 is the Zilog Z16C32 Integrated Universal Serial Controller (IUSC), which features an embedded DMA engine and 32-byte FIFO buffer for robust, high-speed data handling. The card supports synchronous communication speeds up to 10 Mbps (RS-422/485), and 20 Kbps for RS-232, with signal integrity over long distances up to 4000 feet via RS-485.
The board ships with both low-profile and standard-height brackets, ensuring seamless integration into any PCI-based system. Software support via SeaMAC enables quick configuration for HDLC, SDLC, and other legacy protocols.
