The CMV6x86DX cpuModules
The PC/104 cpuModules described in this manual are designed for industrial applications which re-
quire:
• software and hardware compatibility with the PC/AT world
• high-speed "number-crunching" operation
• low power consumption
• small physical dimensions
• high reliability
• good noise immunity
This cpuModule is highly integrated, combining all major functions of a PC/AT computer on one
compact board. It integrates all primary I/O functions of a AT compatible computer:
• keyboard interface
• ECP parallel port
• two versatile RS232/422/485 serial ports
• Real Time Clock
• Speaker port
It also enhances standard AT-compatible computer systems by adding:
• two Solid State Disk sockets
• a non-volatile configuration EEPROM or ATMEL chip
• a Watchdog Timer
• Fail Safe Boot ROM
The figure below shows a simplified block diagram of the cpuModule:
You can easily customize the cpuModule by stacking PC/104 modules such as video controllers,
modems,LANcontrollers,or analoganddigitaldataacquisitionmodules.StackingPC/104modules
on the cpuModule avoids expensive installations of backplanes and card cages and preserves the
module's compactness.

A PC compatibleBIOS is also implemented in the cpuModule. This BIOS supports ROM-DOS and
MS-DOS operating systems. Drivers in the BIOS allow booting from floppy disk, hard disk, Solid
State Disk, Fail Safe Boot Rom, or DiskOnChip. The system can be used with traditional disk drives
or non-mechanical drives.
The cpuModule and BIOS are also compatible with most real-time operating systems for PC com-
patible computers, although these may require creation of custom drivers to use the SSD, EEPROM,
and watchdog timer.
For industrial applications, a set of BIOS functions have also been implemented which allow easy
control of system hardware devices.

CHAPTER 2: GETTING STARTED
For many users, the factory configuration of the cpuModule can be used
to get a PC/104 system operational. If you are one of these users, you can
get your system up and running quickly by following a few simple steps
described in this chapter. Briefly, these steps are:
• Connect power.
• Connect the utility cable.
• Connect a keyboard.
• Connect the PC/104 bus to a video card.
• Booting the cpuModule for the First Time.
• Default Bios Configuration
• Booting to Boot Block Flash with Fail Safe Boot ROM
• If you Misconfigure the cpuModule
Refer to the remainder of this chapter for details on each of these steps.

CN3 Auxiliary power 8 pin
CN4 Factory use only -
CN5 Multifunction 10 pin
CN6 Parallel port 26 pin
CN7 Serialport#1 10pin
CN8 Serialport#2 10pin

15
For a complete listing of connectors, please refer to I/O Connections on page 28.
NOTE! Pin 1 of each connector is indicated by a square solder pad on the bot-
tom of the PC board and a white box silkscreened on the top of the
board.

16
Cable Kits
For maximum flexibility, cables are not provided with the cpuModule. You may wish to purchase
our cable kit for the cpuModule.
The XK-CM10 cable kit contains the following:
• Multifunction cable (keyboard socket, battery, reset, speaker)
• Twoserialportcables(two-DIL10toDSUB9)
• Parallel port cable (DIL26 to DSUB25)
• Power cable (DIL8 to wire leads)

17
Connecting Power
Power is normally supplied to the cpuModule through the PC/104 bus, connectors CN1 and CN2 .
If you are placing the cpuModule onto a PC/104 stack that has a power supply, you do not need to
make additional connections to supply power.
If you are using the cpuModule without a PC/104 stack or with a stack that does not include a power
supply, refer to Auxiliary Power, CN3 on page 30 for more details.
WARNING! If you improperly connect power, the module will almost certainly be
damaged or destroyed. Such damage is not warranted! Please verify
connections to the module before applying power.

18
Connecting the utility cable
The Multifunction connector, CN5, implements the following interfaces:
• AT keyboard
• Speaker output
• System reset input
• Battery input
• Vpp to program 12V Flash SSD devices
To use these interfaces, you must connect to the Multifunction connector, making sure the orienta-
tion of pin 1 is correct. If you are using the Multifunction cable from our cable kit, the cable provides
a small speaker, a 5-pin circular DIN connector for the keyboard, a push-button for resetting the PC/
104 system, and a lithium battery to provide backup power to the Real Time Clock.
To connect individual devices to the Multifunction connector, please see Multifunction Connector,
CN5 on page 39.

19
Connecting a Keyboard
You may plug a PC/AT compatible keyboard directly into the circular DIN connector of the Multi-
function cable in our cable kit. Some newer keyboards may use a smaller "mini-DIN" connector; you
will need an adapter to plug these keyboards into the cpuModule.
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.

20
Connecting to the PC/104 Bus
Since this cpuModule does not include a video display controller, you will probably wish to stack
the cpuModule with another card to add video. For example, you may add the CM112 utilityMod-
ule, which adds a VGA display controller with flat-panel support and a floppy and IDE hard drive
controller, all on one PC/104 module.
The PC/104 bus connectors of thecpuModule are simply plugged onto a PC/104 stack to connect to
other devices.
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 cpuModule on the PC/104 stack.
• Touch a grounded metal part of the rack to discharge any buildup of static electricity.
• Remove the cpuModule from its anti-static bag.
• Check that keying pins in the 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 cpuModule 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 cpuModule onto the PC/104 stack.
WARNING! Do not force the module onto the stack! Wiggling the module or apply-
ing 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.
