Connecting to the Stack
The bus connectors of the cpuModule are simply plugged onto a PC/104 stack to connect to other devices.
Follow the procedure below to ensure that stacking of the modules does not damage connectors or
electronics.
For mechanical dimensions, including board-to-board spacing, see
1. Turn off power to the PC/104 system or stack.
2. Always work at an ESD protected workstation, and wear a grounded wrist-strap.
3. Select and install stand-offs to properly position the cpuModule on the stack.
4. Remove the cpuModule from its anti-static bag.
5. Check that pins of the bus connector are properly positioned.
6. Check the stacking order; make sure all of the busses used by the peripheral cards are connected
to the cpuModule.
7. Hold the cpuModule by its edges and orient it so the bus connector pins line up with the matching
connector on the stack.
8. Gently and evenly press the cpuModule onto the PC/104 stack.
Power Input Connections
Power to the board must come from either the top or bottom PCIe/104 Type 2 bus connectors (
CN1
or
CN2
), or the auxiliary power connector (
CN3
). These connectors provide the re5V DC voltage rail
input to the cpuModule. While the RTD Intel E3800 Series CPU only re5 volts, +12V may
optionally be connected to CN3 if it is required by any other device in the system.
WARNING
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.
WARNING
While the PCI bus connector (
CN16
) has a +12V pin, it is not connected to the
cpuModule, as the pin does not meet the cpuModule’s current requirement. If the cpuModule
is only connected to the power supply via the PCI connector, the cpuModule’s LED will turn
red, indicating that the +12V input rail is not present.
