PinPoint EDGE/GPRS - User Guide, version 2.32 100
AT Commands: Low Power
The PinPoint will put itself into a low power using mode when configured events occur (page 30).
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 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 time to prepare); entering zero will not power down the modem
immediately, but after one minute.
In the first 5 minutes after PinPoint 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 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.
