MVME5500 Single-Board Computer

PMC/SBC Mode Selection

The MVME5500 is set at the factory for SBC/IPMC712 mode. The

SBC/IPMC761 mode should only be selected when using the IPMC761

module in conjunction with the MVME761 transition module.The PMC

mode should be selected when using PMC modules with specific user I/O

in conjunction with the corresponding transition module. PMC mode

should also be selected when using PrPMC modules.

Two 3-pin planar headers (J28, J32) are for PMC/SBC mode selection. For

PMC mode, install jumpers across pins 1-2 on both headers. For

SBC/IPMC761 mode, install jumpers across pins 2-3 on both headers. For

SBC/IPMC712 mode, install a jumper across pins 2-3 for J32 and install a

jumper across pins 1-2 for J28.
