31. The NIM backplane connector is an irregular arrangement of individual pins into sockets in the crate. 32. Unlike a backplane , it also contains the central processing unit and hosts other subsystems and devices. 33. SGPIO is essentially another ( incompatible ) application stack for SPI designed for particular backplane management activities. 34. PICMG expanded the CompactPCI specification with the use of standard Ethernet connectivity between boards across the backplane . 35. The printed backplane of the I / O bus was modular in groups of 8 interface slots. 36. Plus a " backplane card ", ( which connected all the other cards ) and a keyboard. 37. Many DAQ solutions involve the use of DAQ modules, which are cards that plug into a backplane . 38. A NIM crate only has power on the backplane , there is no data bus or data connectors. 39. The pathfinder allowed practicing installing mirror segments with a non-flight mirror and non-flight backplane . 40. CompactPCI was initially ratified as PICMG 2.0 in late 1995 as a passive backplane for PCI signaling.
