2.4.2
Piggyback Interface Connectors for Serial Interface Piggybacks
The VSBC-32(E) is equipped with a set of piggyback interface connectors for serial
interface (SI) piggybacks (three 7-pin row male connectors). The pinout of these piggy-
back interface connectors includes all signals for serial I/O (RS232), PROFIBUS
(RS485) and Ethernet (10BaseT, 10Base5, 10Base2) communication.
For a detailled description of the pinouts of these piggyback interface connectors please
refer to the VITA/
PEP Modular Computers CXC MPI Specification.
2.4.3
Memory Piggyback Interface Connectors
The VSBC-32(E) is equipped with a set of memory piggyback interface connectors (two
50-pin row female connectors). The pinout of these piggyback interface connectors
includes all signals for the connection of up to 128MB of DRAM and up to 4 MB of flash
EPROM.
For a detailled description of the pinouts of these piggyback interface connectors please
refer to the VITA/
PEP Modular Computers CXC MPI Specification.
2.4.4
EPROM DIP Sockets
The VSBC-32(E) is equipped with two sets of (flash) EPROM DIP sockets (two 32-pin
row female sockets). The pinout of these DIP sockets includes all signals for the connec-
tion of up to 1MB of SRAM.
Note...
Although physically all piggybacks fit on bott basic board variants
(IUC-32 and IUC-32E), the MN68360 processor of the IUC-32
variant does not support Ethernet communication. Therefore,
Ethernet piggybacks should be used only on the IUC-32E board
variants.
