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 PC/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 34 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 Some older 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. 26 CME136686LX cpuModule BDM-610000065 Rev C
Connecting to the PC/104 Bus The PC/104 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. 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 system or stack. 2. Select and install stand-offs to properly position the cpuModule on the PC/104 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; 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 stack. Note Before installing ISA add-in cards, refer to the section Using ISA Peripheral Cards on page 64 and I/O Address Aliasing on page 65. BDM-610000065 Rev C Chapter 2: Getting Started 27
