How to connect the CPU-1461 to other PC/104 & PC/104-Plus devices:
the stack assembly
The ISA and PCI Bus connectors of the CPU-1461 are located on the bottom side of the module only, and
are designed to allow the connection on the top position of the stack formed by other PC/104 and/or PC/104-
Plus devices.
We recommend you to follow the procedure below ensuring that stacking of the modules does not damage
connectors or electronics parts.
Always use appropriate antistatic precautions when handling boards
1. Turn off all power to the PC/104 computer and its peripheral devices.
2. Select and install standoffs to properly position the module on the PC/104 stack.
3. Remove the module from its antistatic bag.
4. Check that keying pins in the bus connector are properly positioned.
5. Check the stacking order; make sure an XT bus card are not placed between two AT bus cards as
this will interrupt the AT bus signals.
6. Hold the module by its edges and orient it so that the bus connector pins line up with the matching
connector on the stack.
7. Using even pressure press the module onto the PC/104 stack.
