Introduction 1
CM1-86DX2
1 Introduction
1.1 Overview
The CM1-86DX2 is a PC/104 Single Board Computer (SBC) based on DMP’s Vortex86-DX2
single chip solution, featuring exceptionally high integration and a very good perfor-
mance-to-power ratio. The board supports all peripherals needed for an embedded PC on a
small 3.775" by 4.050" printed circuit board.
The Vortex86-DX2 chip integrates a powerful yet efficient CPU with graphics controller, audio
controller, and Gigabit Ethernet controller to form a complete PC, with all the standard periph-
eral connections onboard.
The board provides two Ethernet ports (1x Gigabit and 1x 100Megabit), four
RS232/RS422/RS485 serial ports, one USB 2.0 host controller, one USB 1.1 host controller to
handle the communication with external devices, and PS/2 connectors for keyboard and
mouse. A first generation SATA interface allows the connection of hard disk or CD drives. Appli-
cations that require non-moving storage can use the MicroSD-Card slot or the bootable flash.
System expansion is possible easily over the PC/104, Mini-PCI-Express and I²C bus connec-
tors.
The CM1-86DX2 is powered by a 5V-only supply and runs DOS, Windows XP/7 and Linux
operating systems. The Vortex86-DX2 SoC has a simulated ACPI to support Windows 7
(though S3 or S4 modes are not supported.)

with the components located around the mounting holes. This can damage
the board.

2.3 Hardware Setup
Use the cable set provided by ADLINK Technology to connect the CM1-86DX2 to a VGA moni-
tor. Connect either PS/2 or USB keyboard or mouse, respectively. Use the SATA cable to con-
nect the hard disk. Make sure that the pins match their counterparts correctly and are not
twisted. If you plan to use additional peripherals, connect them to the appropriate headers.
Connect a 5 volt, 5 amps power supply to the power connector and switch on the power.
The display shows the BIOS messages. If you want to change the standard BIOS settings,
press the <DEL> key to enter the BIOS menu. See Chapter 4 for setup details.
If you need to load the BIOS default values, they can be automatically loaded at boot time.
The CM1-86DX2 boots from CD drives, USB floppy, USB stick, hard disk or µSD-Card. Provided
that any of these is connected and contains a valid operating system image, the display then
shows the boot screen of your operating system.
The CM1-86DX2 needs adequate cooling measures depending on the desired operating tem-
perature range. Using the board without cooling could damage the board permanently.
Be sure to observe the EMC security measures. Make sure you are always at the same
potential as the module.
Never connect or disconnect peripherals like HDDs, PCI, and ISA boards while the board's
power supply is connected and switched on.
The 5 amps value is the minimum you should have for the standard peripherals
mentioned. For additional peripherals, make sure enough power is available. The
system will not work if there is not enough supply current for all your devices.
