Ams trex™ Device Communicator

Power management option
Description
Dim Display (Backlight) timer
Dim the backlight after a period of inactivity.
Suspend timer
Turn off the backlight after a period of inactivity. Device
communication and power are not interrupted.
Note
If the Suspend timer is enabled, the Shut Down timer is ignored.
Disable the suspend timer by setting the timer to Never to
maximize the battery charge of your Trex unit.
Shut Down timer
Shut down the Trex unit after a period of inactivity.
When the AC adapter is connected to the power module, all the timers are disabled. It is
recommended to connect your Trex unit to the AC Adapter when not in use to ensure full
charge of the power module and maximize the life of the battery.
Note
The timers are cumulative. For example, if you set the Dim Display (Backlight) timer to 5
minutes, the Suspend timer to Never, and the Shut Down timer to 10 minutes, the Trex
unit shuts down after 15 minutes of inactivity.
Enter or exit suspend mode
Suspend mode is similar to standby mode on a phone. The screen is turned off, but all
connectivity is maintained. If the Trex unit is powering a device before entering suspend, it
continues to power and communicate with the device. If a Trex unit is connected to a
network, it remains connected in suspend mode. You can put the Trex unit in suspend
mode, or wait for the suspend timer to expire.
When in suspend mode, the Trex unit shuts down if there is no activity (key presses) after a
specified amount of time. Use the 
Turn off after
option on the 
Power Management
screen to specify this time.
