Port to bus module (X20)
The computer unit has a bus module with a PCI expansion slot and a shared
ISA/PCI slot. Expansion boards can be installed complying with ISA specification
(Rev. 3.1) and PCI specification (Rev. 2.0) with a maximum length of 265 mm
(175 mm for shared ISA/PCI modules) (see Chapter 4). All PCI slots can be used
as masters. Only 5 V PCI modules can be operated.
The power supply of the expansion boards runs via the connection of the bus
module to the basic board. The -5 V voltage is not provided by the power supply
and is generated from the -12 V on the bus module using in-phase control.
The connection to the basic board is established by a gold-plated ’EISA’ type
two-part connector. All the necessary bus signals (ISA and PCI) are applied to this
connector. The following table shows the connector pin assignment.
