INSTALLING THE UTILITYMODULE
Since the utilityModule uses a PC/104 stackthrough bus, the only hardware installation you will
do is placing the module to the PC/104 stack. To do this, you will connect the PC/104 bus
connector with the matching connector of another module.
Recommended Procedure
We recommend you follow the procedure below to ensure that stacking of the modules does not
damage connectors or electronics.
•Turn off power to the PC/104 system or stack.
•Select and install standoffs to properly position the utilityModule on the PC/104 stack.
•Touch a grounded metal part of the stack to discharge any buildup of static electricity.
•Remove the utilityModule from its anti-static bag.
•Check that keying pins in the PC/104 bus connector are properly positioned.
•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.
•Hold the utilityModule by its edges and orient it so the bus connector pins line up with the
matching connector on the stack.
•Gently and evenly press the utilityModule onto the PC/104 stack.
CAUTION: Do not force the module onto the stack! Wiggling the module or applying too
much force 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.

PC/104 Bus Connectors, CN1 and CN2
CMT106 IDE controller utilityModule 8 Real Time Devices USA, Inc.
PC/104 Bus Connectors, CN1 and CN2
Connectors CN1 and CN2 provide PC/104 bus connections. CN1 carries XT bus signals, and CN2
carries additional signals for the AT bus. The signals on CN1 and CN2 conform to the IEEE P966
standard for the PC/104 bus.

Note: Two locations on the bus have mechanical keying pins to help prevent
misconnection of the PC/104 bus. These keying pins are a part of the PC/104
standard, and we strongly recommend you leave them in place.
If you have other modules without keying pins, we suggest you modify them to
include keying.

USING THE UTILITYMODULE
IDE Hard Disk
The CMT106 provides an IDE interface to 2.5 inch, 2.1 Gbyte harddrive. This harddrive can be
set up as the primary or the secondary drive (you must be sure that your CPU bios supports both
primary and secondary drives). The CMT106 cannot be used as a slave drive.
Since the CMT106 provides the IDE decoding on-board, there is no need for any cabling. You
must be sure to disable any other IDE controllers that might be present on your CPU module or
VGA module.
You may need to run the setup program for your cpuModule or computer to configure the correct
hard drive type.
NOTE: If you are using this harddrive with an RTD CPU module, enter 4095
for the number of cylinders.
Power Protection Circuitry
To reduce the risk of damage due to power-supply problems, the utilityModule includes several
protective components.
Module Power-Supply Protection
The utilityModule includes components to help prevent damage due to problems with the +5Vdc
power supply from the PC/104 bus or power-supply connector. Protection is provided for:
•Over-current
•Reversed polarity
•Excessive voltage
This protection is only for the utilityModule, and will not protect other devices in a PC/104 stack .
The protective fuse is replaceable and is available from electronics suppliers. Its description and
part number are:
Littelfuse Nano2SMF 1.0 amp, R451-001
Caution: Replace fuses only with parts of identical current and voltage rating.
