1.1.7 External Connection The PMC421 offers both front and rear I/O. The front I/O is a high-density 68-pin connector. The 68-pin connector mates with a separate cable to provide standard connection to 8 DB-9 male connectors (purchased separately).
Provision to augment firmware with special protocol handling (e.g., encryption) with minimum effort. (All firmware is in high-level language.) The PMC421 takes advantage of the most recent technology in UART implementation, which allows deeper hardware buffers and control to further augment overall data flow.
Driver Driver Driver Driver Driver Driver Driver Driver 2.1 Functional Components The PMC421 can be broken into several functional components: • PCI Interface • intelligent Co-Processor (IOCP) Firmware execution • UART (Data serializes) • Signaling Drivers The following paragraphs describe each component.

“per port” basis. 2.1.4 Signaling Drivers A design goal of the PMC421 was to maximize the amount of configuration that can be done under software control, including setting of the electrical signaling characteristics. Each port can be set to RS232, RS422 or RS485 signaling standard under software control of the IOCP.
Work at an approved anti-static work station when unpacking boards. 3.2 Unpacking Instructions RAMiX products are shipped in individual, reusable shipping boxes. When receiving the shipping container, inspect it for any evidence of physical damage. IF the container is damaged, request that the carrier’s agent be present during the unpacking of individual boxes and the inspection of each unit.
