Power.exe - Intermec Janus 2020 User Manual

POWER.EXE

POWER.EXE lets you adjust the reader's power management at the DOS
prompt. It provides power-saving features and an application program
interface (API) that applications can use. POWER.EXE works through the
Advanced Power Management (APM) interface. IRL programs and programs
that use Reader Services do not require POWER.EXE.
To change the level of power management, type this command at the reader's
DOS prompt:
Syntax:
[ drive :][ path ]power.exe [adv[:max | reg | min] |
where:
drive:path
adv:max
adv:reg
adv:min
std
off
low
To display the current power setting, type the command:
Notes:
power
You can view the power settings screen with the viewport or use Interlnk to
view the settings on the host.
POWER.EXE is embedded in the software and is set by default to adv:min.
The JANUS 2020 has its own power management for maximum efficiency.
POWER.EXE gives you an estimate of the amount of NiCad power is left in the
reader's battery pack. This estimate is accurate to ± 10 %. The accuracy of the
estimate depends upon variables such as the temperature and age of the
battery pack. You may find that POWER.EXE performs differently for each
battery pack. For example, when POWER.EXE indicates that the battery life is
at 20%, the battery pack is getting low and you need to replace it soon.
std | off][/low]
specifies the location of the POWER.EXE file.
conserves the reader's power when applications and hardware
devices are idle. Performance may be affected if an application is
active instead of idle. Use max for maximum power
conservation. Use reg to balance power conservation with
performance. Use min (default) if performance is not
satisfactory with max or reg.
conserves the reader's power. Use std to conserve power by
using only the power management features of your hardware.
Use off to turn off POWER.EXE. If POWER.EXE is off, the date
is not updated when you turn off the reader. If you use your
own APM interface, it should be able to update the date each
time the reader is turned on and the date has changed.
loads POWER.EXE into conventional memory, even if the upper
memory area is available. By default, POWER.EXE is loaded
into upper memory if it is available.
