connector
Restrictions regarding installation of particular PC/104+ expansion boards on the module are
described in Section 7.
4.3.13 PC/104 connector
It is possible to connect additional expansion boards with the PC/104 interface (ISA bus, 8/16 bits,
8.3/16.6 MHz, DMA support) to the module. The master mode is not supported for
РС/104 bus.
The interface is routed to the XS2 connector (PC-104 connector, 104 pins, 2.54 mm pitch).
The assignment of the XS2 connector pins and the default load-carrying capacity of the ISA bus
circuits are given in Table 4.23.
The module has an AMP 1375795-5 connector and an AMP 1445251-1 organizer.
