The AD CR5/PMC Dual PMC Carrier Board can be used with a range of Concurrent Technologies VME PMC host processor boards. The carrier board allows two PMC modules to be added to the host processor board, thereby increasing the flexibility and functionality of the host board. Standard PMC modules include SAS, LAN, WANs, Graphics, Communications and Modems. Non-monarch mode Processor PMCs (PrPMC) modules can also be used. For harsher environments, extended temperature versions are supported. The AD-CR5/PMC is pin-compatible with the rear I/O of the popular AD-CR2/PMC Dual PMC Carrier board.
