Connecting the Utility Cable

The multi-function connector (CN5) implements the following interfaces:

PC/AT compatible keyboard

PS/2 mouse port

Speaker port (0.1W output)

Hardware Reset input

Battery input for Real Time Clock

Soft Power Button input

To use these interfaces, you must connect to the utility port connector (CN5). The utility harness from the RTD cable kit provides a small speaker, two connectors for the keyboard and mouse, a push-button for resetting the PCI-104 system, a soft-power button, and a lithium battery to provide backup power for the real time clock.

Refer to Utility Port Connector (CN5) on page 28 to connect devices to the utility port connector.

Connecting a Keyboard

You may plug a PC/AT compatible keyboard directly into the PS/2 connector of the utility harness in the cable kit.

Note Many keyboards are switchable between PC/XT and AT operating modes, with the mode usually selected by a switch on the back or bottom of the keyboard. For correct operation with this cpuModule, you must select AT mode.

Connecting to the PC/104-Plus(PCI) Bus

Other PC/104-Plusor PCI-104 expansion boards may be connected to the cpuModule’s PC/104-Plus(PCI) bus connector. To connect expansion modules to the PC/104-Plusbus, follow the procedure below to ensure that stacking of the modules does not damage connectors or electronics.

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.

1.Turn off power to the PC/104-Plusor PCI-104 system or stack.

2.Select and install stand-offs to properly position the cpuModule on the stack.

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

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

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

6.Check the stacking order; if a PCI to ISA bridge card is used to connect any PC/104 modules, 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 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-Plusor PCI-104 stack.

There are three additional considerations to make when using the PCI bus:
