Figure 4. ISA BUS layout

According to PC/104 specifications, KEY are filled holes in the upper side and missing pins in the lower side

of the bus. This is made to avoid the wrong insertion in/of another module.

18 PC/104Plus – CPU-1432 Module

The PCI BUS

Connector J3 carries signals of the PCI Bus. The PCI Bus mechanical interface is a stackable 30x4 header.

This interface carries all of the required PCI signals per PCI Local Bus Specification Version. 2.1.

Below is shown a picture of the PCI BUS

For further info about ISA bus and PCI bus please refer to Eurotech site (www.eurotech.it) in

the section Industry Standards.

How to connect to the CPU other PC/104 & PC/104Plus devices: the stack assembly

The ISA Bus connectors of the module are designed to allow the connection onto a stack of other PC/104

and/or PC/104Plus devices.

We recommend you to follow the procedure below ensuring that stacking of the modules does not damage

connectors or electronics parts.

1. Turn off power to the PC/104Plus system or stack.

2. Select and install standoffs to properly position the module on the PC/104Plus stack.

3. Touch a grounded metal part of the rack to discharge any buildup of static electricity.

4. Remove the module from its anti-static bag.

5. Check that keying pins in the bus connector are properly positioned.

6. Check the stacking order; make sure an XT bus card will not be placed between two AT bus cards or it

will interrupt the AT bus signals.

7. Hold the module by its edges and orient it so that the bus connector pins line up with the matching

connector on the stack.

8. Press evenly the module onto the PC/104Plus stack.

The picture below shown a typical module stack with 2 PC/104Plus modules, 1 PC/104 16-BIT module, and

1 PC/104 8-BIT module.

The maximum configuration for the PCI bus of PC/104Plus modules is 4 plus the Host Board.

If standard PC/104 modules are used in the stack, they must be the top module(s) because they will

normally not include the PCI bus.

Figure 6. The Module Stack

Do not force the module onto the stack! Wiggling the module or applying too much pressure

may damage it. If the module does not readily press into place, remove it, check for bent pins

or out-of-place keying pins, and try again.
