On Mode (D0); User Idle / Backlight Off Mode (D1); System Idle / Display Off Mode (D2); Suspend Mode (D3) - Honeywell Thor VM2 User Manual

On Mode (D0)

When the Thor VM2 is attached to either vehicle power or an external power supply or is operating from the UPS bat-
tery and the power button is pressed, the Thor VM2 is in the On mode. In this mode, the keypad, touch screen and any
attached peripherals such as a scanner function normally. The display remains on until the backlight timer (if enabled)
expires.

User Idle / Backlight Off Mode (D1)

Backlight is dimmed, but display is readable. The Thor VM2 transitions to this mode from On after the User Idle time-
out period has passed without a primary even occurring.

System Idle / Display Off Mode (D2)

Backlight and display are off. The status LED is solid green. The Thor VM2 transitions to this mode from User Idle
after the System Idle timeout period has passed without a primary event occurring.

Suspend mode (D3)

All devices that are not configured as wakeup events are powered off. The status LED is blinking green if external
power is connected and off if external power is not connected. The Thor VM2 transitions to this mode from System Idle
after the Suspend timeout period has passed without a primary event occurring.
By default power is turned off to the USB port when the Thor VM2 is in Suspend. The Thor VM2 can be configured to
provide power to the USB port in Suspend using the
Additionally the power button can be used to enter or exit Suspend mode:
• If the Thor VM2 is On, pressing the power button immediately transitions the unit to Suspend.
• If the Thor VM2 is in Suspend mode, pressing the power button transitions the unit to On.

Shutdown / Off Mode (D4)

The Thor VM2 shuts down when the Thor VM2 is operating on power and the UPS battery becomes critically low
regardless of the current power management state. The Thor VM2 remains Off until external power is applied. The
Thor VM2 may restart automatically when external power is applied or may require the user to press the Power button
depending on installation and configuration.
The Thor VM2 transitions to Off mode from Suspend after the Shutdown timeout period has passed without a primary
event occurring. If the Thor VM2 has external power applied or a sufficiently charged UPS battery the Thor VM2 may
restart automatically or may require the user to press the Power button depending on installation and configuration.
A Real Time Clock (RTC) powered by an internal battery maintains the date and time while the Thor VM2 is off.

Primary Events

The Primary Events described below are the default behavior. Primary events can be modified using the LXEPower-
MgrPrimaryEvents API.
Please refer to the CE API Programming Guide for API details.
User Primary Events
A User Primary Event transitions the Thor VM2 to D0 (On) mode. When no user event happens for the specified
time period, the Thor VM2 transitions to D1 (User Idle), then D2 (System Idle) and then D3 (Suspend). Timeout
periods are set via the Schemes tab in the Power control panel.
User primary events include:
• Any key press on the integrated keypad or external USB keyboard
• Touch on the touch screen
System Primary Events
A System Primary Event allows the Thor VM2 to transition to D2 (System Idle) but the Thor VM2 does not enter
D3 (Suspend) as long the system event occurs.
System primary events include:
• Serial data transfer
• USB data transfer
