    MVME712-13 The manual also provides information about the LCP2 Adapter Board. The transition modules are used as the interface between Motorola Single Board Computer VMEmodule families, such as the MVME147S, MVME162, MVME167, MVME187, and MVME197, and their peripheral devices. An LCP2 adapter module and a cable are supplied for interconnection between the MVME712 family module and the MVME1xx family module.

  • Page 14: Cooling Requirements

    Cooling Requirements Motorola VMEmodules are specified, designed, and tested to operate reliably with an incoming air temperature range from 0 degrees C to 55 degrees C (32 degrees F to 131 degrees F) with forced air cooling. Temperature qualification is performed in a standard Motorola VMEsystem 1000 chassis. Twenty-five watt load boards are inserted in the two card slots, one on each side, adjacent to the board under test to simulate a high power density system configuration.
