8 PinPoint Specific AT Commands These AT commands are specific to the AirLink PinPoint.
Command
Description
DTRP=n [?] 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
NOTE: Also see PTMR
GPSn Send NMEA GPS strings out serial link.
ATGPS will cause the NMEA GGA, RMC, and VTG GPS strings to
output to the serial port one time.
ATGPS1 will cause these strings to be sent out the serial link once
per second forever.
ATGPS0 will stop the feed.
PTMR=n [?] 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. If DTRP and VLTG are both 0 (zero), this setting does
nothing.
NOTE 1: There is always a minimum of 1 minute between power
down event and actual shutdown (to give the modem time to
prepare); entering zero will not power down the modem
immediately, but after one minute.
NOTE 2: In the first 5 minutes after modem powers up, power
down events are ignored to give the user time to change
configurations.
VLTG=n [?] Set or query the voltage level at which the PinPoint goes into low
power mode.
n = 0: Ignore voltage for power control
n = low power voltage threshold in tenths of volts.
Example: ATVLTG=130 would power down the modem if the
voltage goes below 13.0V.
*DTRI=n Enable monitoring the DTR signal as in input event.
n = 0: Disable DTR input monitoring
n = 1: Enable DTR input monitoring
NOTE: If DTR is used as an input, DTR cannot be used for low-
power control. (See DTRP)
