PinPoint-E EDGE/GPRS - User Guide, version 2.32 103
AT Commands: Low Power
The PinPoint-E will put itself into a low power using mode when configured events occur
(page 32). Low Power mode is essentially a standby mode which uses minimal power while being
ready to “come alive” quickly.
FIGURE 1. Common : Low Power
DTRP=n
PTMR=n
VLTG
Low Power
Set or query the DTR power control.
n=0 : Ignore DTR for power control.
n=1 : Enter low power mode when DTR is low.
n=2 : Enter low power mode when DTR is high.
See also PTMR.
Number of minutes after one of the power down events (VTLG or DTRP) happens until the
PinPoint-E enters the low power mode.
n=0 - 255 minutes
If DTRP and VLTG are both 0 (zero), this setting does nothing.
Note: There is always a minimum of 1 minute between power down event and actual shut-
down (to give the
PinPoint-E time to prepare); entering zero will not power down the
modem immediately, but after one minute.
In the first 5 minutes after PinPoint-E powers up, power down events are ignored
to give the user time to change configurations.
Set or query the voltage level at which the PinPoint-E goes into low power mode.
n=threshhold in tenths of volts
Example: ATVLTG=130 would place the modem in a low power use, standby state if the
voltage goes below 13.0V.
n=0 : Ignore voltage for power control.
