System
The PCM-VDX-2-512 is a fanless PC/104 single board computer (SBC) based upon the ultra low power Vortex86DX
processor. It requires about 6 Watts under full load while operating over an extended temperature range of -40°C to 85°C.
The board has 512 MB soldered on DDR2 SDRAM, Ethernet, USB, serial and parallel I/O, as well as PC/104, MiniPCI
expansion, and optional external battery. This board replaces older generation WinSystems’ and other manufacturers’
386SX, 486DX, 586, and SC520 based SBCs. A 500 MHz model is also available.
Memory
The PCM-VDX-2-512 board is built with 512 MB of SDRAM soldered directly to the PCB. Additionally, 512 MB of
soldered-on ash SSD is optional for this board. 1 MB of SRAM is included for user data space. This RAM may be
battery backed to maintain data integrity during power off conditions.

Interrupt Map
Hardware Interrupts (IRQs) are supported for both PC/104 (ISA) and PCIe devices. The user must reserve IRQs in the
BIOS CMOS conguration for use by legacy devices. The PCIe/PnP BIOS will use unreserved IRQs when allocating
resources during the boot process. The table below lists IRQ resources as used by the PCM-VDX-2-512.
IRQ0 18.2 Hz heartbeat
IRQ1 Keyboard
IRQ2 Chained to Slave controller (IRQ9)
IRQ3 COM2 *
IRQ4 COM1 *
IRQ5 USB/On-board Ethernet
IRQ6 USB
IRQ7 LPT *
IRQ8 Real-Time Clock
IRQ9 COM3 *
IRQ10 Available
IRQ11 COM4 *
IRQ12 Mouse
IRQ13 Floating point processor
IRQ14 IDE
IRQ15 Available
*
These IRQ references are default settings that can be changed by the user in the CMOS Settings
utility. Reference the PCI Congurations section under Advanced Settings.
**
IRQ9 is commonly used by ACPI when enabled and may be unavailable (depending on operating
system) for other uses.
*** IRQ15 is currently unavailable under the Windows operating systems.
Some IRQs can be freed for other uses if the hardware features they are assigned to are not being
used. To free an interrupt, use the CMOS setup screens to disable any unused board features or their
IRQ assignments.

Watchdog Timer
The PCM-VDX-2-512 features an advanced watchdog timer which can be used to guard against software lockups. Two
interfaces are provided to the watchdog timer. The Advanced interface is the most exible and recommended for new
designs. The other interface option is provided for software compatibility with older WinSystems single board computers.
Advanced
The watchdog timer can be enabled in the BIOS Settings by entering a value for Watchdog Timeout on the Chipset →
SouthBridge Conguration screen. Once the operating system is loaded, the watchdog can be disabled or recongured in
the application software.
NOTE: It is recommended that a long timeout be used if the watchdog is enabled when trying to boot any operating
system.
The watchdog can be enabled, disabled or reset by writing the appropriate values to the conguration registers located
at I/O addresses 565h and 566h. The watchdog is enabled by writing a timeout value other than zero to the I/O address
566h and disabled by writing 00h to this I/O address. The watchdog timer is serviced by writing the desired timeout value
to I/O port 566h. If the watchdog has not been serviced within the allotted time, the circuit resets the CPU.
The timeout value can be set from 1 second to 255 minutes. If port 565h bit 7 equals 0, the timeout value written into I/O
address 566h is in minutes. The timeout value written to address 566h is in seconds if port 565 bit 7 equals 1.

Watchdog Timer Examples
Legacy
This interface is provided for legacy software support only and is not recommended for new development.
The watchdog can be enabled or disabled via software by writing an appropriate timeout value to I/O port 1EEH. See the
chart provided below.
140808 PRODUCT MANUAL PCM-VDX-2-512 18
Real-Time Clock/Calendar
A real-time clock is used as the AT-compatible clock/calendar. It supports a number of features including periodic and
alarm interrupt capabilities. In addition to the time and date keeping functions, the system conguration is kept in CMOS
RAM contained within the clock section. A battery must be installed for the real-time clock to retain time and date during a
power down.

140808 PRODUCT MANUAL PCM-VDX-2-512 20
An optional external battery, connected at J8, supplies the PCM-VDX-2-512 board with standby power for the real-time
clock and CMOS setup RAM. An extended temperature lithium battery is available from WinSystems, part number
BAT-LTC-E-36-16-1 or BAT-LTC-E-36-27-1.
A power supervisory circuit contains the voltage sensing circuit and an internal power switch to route the battery
or standby voltage to the circuits selected for backup. The battery automatically switches ON when the VCC of the
systems drops below the battery voltage and back OFF again when VCC returns to normal.
For OEM applications, an on-board battery may be populated. Please contact your WinSystems’ Application Engineer
for additional information.
(For external battery. Provides battery backup to RTC and BIOS CMOS.)
