PMC522/FP 為將串行 I/O 要求集成到 VMEbus 或 CompactPCI 系統(tǒng)中提供了獨(dú)特的有效解決方案。PMC522/FP 在單個(gè) PMC 卡上實(shí)現(xiàn)，與當(dāng)前一代 VMEbus 和 CPCI 單板計(jì)算機(jī)以及任何包含 PMC 連接器的專用處理器完全兼容。

In addition, the PMC422 and PMC422/FP have a 16-bit general purpose Timer/Counter with 8 general-purpose bs. The 8 bits can be set with switches on-board and read by the host. A total of 256 combinations are possible.?PIM (PMC I/O Module) per VITA standard VITA 36-199X
The PIM422 is designed to give rear access I/O when used in conjunction with RAMiX's PMC421, PMC422 orPMC423. The PIM module mates to rear transition modules (refer to the assembly diagram in section 5), which have been designed to the PIM standard.
The PMC specification provides for user defined I/O to exit the PMC through one or more 64 pin connectors. This user I/O is commonly employed to bring I/O to the rear of the system in order to augment or replace the I/O available on the PMC’s bezel at the front.
The benefits of using a PMC module to add functionality at the system integration level (as opposed to being designed onto the host board) are well known. The development of the PIM standard now allows for a unib b to route this I/O to the system panel
