1. Getting Started
1.1 0BSafety Precautions
Warning!
Always completely disconnect the power cord from your
chassis whenever you work with the hardware. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by sudden power
surges. Only experienced electronics personnel should
open the PC chassis.
Caution!
Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution,
use a grounding wrist strap at all times. Place all electronic
components in a static-dissipative surface or static-shielded
bag when they are not in the chassis.

Definition
Vehicle Power Mode
BIOS sets up as Vehicle PC
ACC Function (JACC1) sets up as Enable
AT/ATX Jumper (SW1) sets up as AT
Industrial PC Power Mode
BIOS sets up as Industrial PC
ACC Function (JACC1) sets up as Disable
AT/ATX Jumper (SW1) sets up as AT or ATX
ACC Function (JACC1)
- It is Vehicle PC power mode (Power on/off controlled by Ignition or Power
button) if ACC Function sets up as Enable.
- It is Industrial PC power mode (Power on/off controlled by Power button)
if ACC Function sets up as Disable.
AT/ATX Jumper (SW1)
This function will be active if ACC Function (JACC1) sets up Disable
(Industrial PC power mode).
Power Input Selection (SW2)
To set up the DC input voltage is +12Vdc, +24Vdc or wide range from
+9~36Vdc.
Vin Work/Shutdown (BIOS)

VMS-CFS
12 VMS-CFS Quick Reference Guide
- To set up the startup/shutdown voltage in accordance with DC input
voltage as +12Vdc, +24Vdc or wide range from +9~36Vdc.
- The following behaviors happen if ACC Function (JACC1) sets up as
Enable:
VMS-CFS won’t power on if the DC Input voltage is lower than the startup
voltage.
VMS-CFS will automatically power on, if the DC input voltage reaches the
startup voltage.
VMS-CFS will automatically power on, if the DC input voltage reaches the
startup voltage and power on delay ends up (the power on delay is Enable in
BIOS).
VMS-CFS will automatically power off, if the DC input voltage is lower than
shutdown voltage, and the time exceeds 60sec. If it still doesn’t power off and
the time exceeds 6min, VMS-CFS will be forced power off immediately.
Power on delay time is selectable by BIOS in following hierarchies
10sec / 30sec / 1min / 5min / 10 min / 15min / 30min / 1hr.
The delay time starts to count if ignition turns on.
User can skip the delay time to turn on VMS-CFS if pressing power button.
VMS-CFS will automatically power on if the delay time ends up.
Power off delay time is selectable by BIOS in following hierarchies
20sec / 1min / 5min / 10min / 30min / 1hr / 6hr / 18hr.
The delay time starts to count if ignition turns off.
User can skip the delay time to turn off VMS-CFS if pressing power button.
VMS-CFS will automatically power off, if the delay time ends up. If it still
doesn’t power off and the time exceeds 60sec, VMS-CFS will be forced power
off immediately.
S3, S4 suspend mode
In the vehicle power mode, the S3/S4 is only able to resume from power
button.
The status of Ignition On/Off is detectable by SW
The status of Low battery is detectable by SW
VMS will shut down automatically when internal temperature is reach the
setting (it is selectable by BIOS).

VMS-CFS will cancel the delay function, and then continue to operate
normally, if the ignition is turned on again and the power off delay is in
process.
VMS-CFS will shut down completely, and then power on again automatically,
if the ignition is turned on again and the power off delay ended.
VMS-CFS will cancel the delay and stayed in power off status, if the ignition is
turned off again and power on delay is in process.
VMS-CFS is only 10mA if it is off.
