Configuration 3 - 17
Device Activity Management (Sleep/Wake-up Functionality)
Use the Device Activity Manager to manage the device usage profile and lifecycle by turning on/off the scan engine
laser and the display backlight. Set the sleep and wake-up times by day, weekday, weekend, etc. When setting the
time, use the 24-hour clock in the format hh:mm.
If the Device Activity Manager (DAM) puts the scan engine and/or backlight into sleep mode, these subsystems
repower (wake up) upon the following events:
•
a button press
•
a display touch.
The DAM only checks whether to turn devices on or off when the Inactivity Application Timeout expires. If a device
wakes up due to user input (a “wakeup”), it remains awake regardless of user input until another timeout expires,
then goes back to sleep.
To use the DAM without the Inactivity Application Manager, configure the Inactivity Application Timeout to the
default wakeup time and set the Inactivity Application parameter to nothing.
Printing
The MK1200 supports printing text, bar codes, and bitmaps in the following environments:
•
Browser applications
•
C/C++ applications.
The MK1200 transmits data to a printer using an RS-232 serial connection. RS-232 serial port settings (port, stop
bits, data bits, parity) are shared with the tethered scanner.
Table 3-5 contains the default baud rate settings for the
following printers:
•
Zebra (QL320, Cameo, Encore)
•
Zebra (LP2824/TLP2844)*
•
Zebra EPL Series (LP/TLP 2824, LP/TLP 2844, TLP 3842)
•
Zebra ZPL (LP/TLP 2844-Z, TLP 3844-Z)
•
Epson TML90
•
Epson TMT88III.
* Zebra LP printers ship in Gap mode. If using a printer in Continuous Paper mode, the autosense does not work
and you must manually set the gap to zero. To avoid this, send a command to the printer to change the mode.
Refer to the Zebra printer documentation.
NOTE
It is strongly advised to use the Device Activity Management functionality.
NOTE Use the RDM or System Menu to set up the Device Activity Manager. Enter valid values to all DAM
parameters (see
page 3-10 ). Otherwise the system rejects the input values and the DAM does not invoke
the Inactivity Application.
