The Abaco Systems / Ramix CP237 is a 6U CompactPCI (cPCI) PMC carrier that expands embedded systems by hosting two Peripheral Component Interconnect Mezzanine Card (PMC) slots. It bridges PMC modules to the cPCI backplane, routing rear I/O signals through J3 and J4 connectors to support modular, distributed architectures. The carrier accommodates both 32-bit and 64-bit PMC operation at 33 MHz or 66 MHz bus speeds, with 66 MHz operation available through selective component de-population. Hot-insertion capability enables system maintenance without downtime—essential for high-availability deployments. An optional Enhanced IDE/ATA interface supports boot or data storage via rotating or flash disk. Optional 10/100Base-TX Ethernet and RS232 serial ports extend connectivity options.
