Power Modes
On
When in the On state, the display (touch screen) is on. The keyboard, touch screen and all peripherals function normally.
The display backlight is on until the User Idle timer expires. The display does not turn off until the System Idle timer expires.
Only interrupts classified as User Activity events will keep the unit in the On state.
MX9 User Activity Events are:
Note: These items are not configurable selections.
• Any key on the keypad except the Power key
• Incoming data through scanner port
• Touch screen tap
• Trigger pull
The user is presented with a Power applet in the Control Panel. One tab in the applet, Schemes, is designated for the
power management timeouts. This tab displays three transition states, User Idle, System Idle and Suspend.
Additionally, the OS provides a Backlight tab on the Display control panel. The Backlight tab allows the user to select the
same timeout ranges provided by the User Idle scheme timers. Any changes on the Display > Backlight tab will also
change the Power > Schemes > User Idle timer, and vice-versa.
The backlight for the keypad (if enabled) will always follow the display backlight.
User Idle
When transitioning from the On power state to the User Idle power state, the keypad backlight (if enabled) is dimmed and
the display backlight is dimmed. User Activity Events listed below will transition the system back to the On state.
User Idle timers are set using Start > Settings > Control Panel > Power > Schemes tab.
Only interrupts classified as System Activity events will keep the MX9 awake in this state until a deliberate user action to put
the unit into Suspend or power Off occurs. An event must be specifically coded to wake up from this state.
The following User Activity events DO transition the unit from the User Idle state to On state:
Note: These items are not configurable selections
• Any key on the keypad except the Power key
• Incoming data through the scanner port
• Touch screen tap
• Unit docked in powered cradle
• Trigger pull
• Incoming Bluetooth connection or data on the virtual COM port
• Connection of USB Device to host port
Note: The scanner port is defined as a software (SW) port. Any hardware (HW) device that sends data to the software (SW)
defined scanner port will transition the unit from User Idle to On.
The following events DO NOT wake the unit from the User Idle state or reset the timers:
•COM1 CTS
• Serial connection
• USB client connection to a host PC
• Power key press (transitions to Suspend)
Example: Bluetooth Voice will not transition the unit from User Idle to On. Bluetooth Scan data will transition the unit to On
as it sends the data to the scanner port.
System Idle
After transitioning to the User Idle power state, the timer is started for the transition to System Idle. When this timer expires
without any further user activity, the keypad backlight (if enabled) is turned off and the display is turned off. Only interrupts
classified as System Activity events will wake the unit from System Idle to User Idle. Any activity classified as User Activity
will transition from System Idle to On.
System Idle timers are set using Start > Settings > Control Panel > Power > Schemes tab.
