Raven and PinPoint CDMA User Guide Version 1.12

A new IP update will be sent anytime the remote Raven detects that its IP has
changed. A periodic update is a redundant process that guarantees the host Raven
will be updated in the event the host Raven loses its IP list for any reason or the
remote Raven’s IP is changed or dropped without notification to the remote Rav en.
Configure the frequency the IP update will be occur.
AT*IPMGRUPDATE[1|2]=n
where n = minutes [0-255]
Other parameters may need to be changed, but this is dependent on the RTU type
being used.
Remember to save your configuration with AT&W.
7.1 Low-power Mode
A PinPoint 9612 can be configured to enter a low power mode in order to conserve a
vehicle’s battery life. The PinPoint can power down when the voltage to the modem
drops below a configured threshold (caused by the vehicle being turned off), or when
DTR changes (usually a contact or voltage controlled by the key switch, signaling
when the vehicle is turned off). For now see the PinPoint 9612 CDPD User Manual.
Important: the external DB9’s RTS and DTR pins can be configured through ATS to
be used as digital inputs. If one or both pins have been configured to be used as
inputs, then low power mode cannot be keyed off of DTR.
7.1.1 Effect on Modem State
Once the transition from powered on to low-power mode starts, the modem will
change state to AT mode. This results in the current mode (e.g. PPP, TCP, etc.) being
gracefully terminated. For the brief period when the modem is preparing for low-
power mode, the modem will remain in AT mode (i.e. won’t auto-answer, ATD will
fail, etc.). Once low-power mode is entered, the modem will then discard any data
received on the host port.
When the modem is woken from low-power mode, the same behavior occurs as upon
power on. The modem starts in AT mode, and then after 5 seconds will enter the
default mode (MD).
7.2 Real-Time Clock Sync
Every hour, the modem will re-sync the internal RTC with the UTC time received
from the GPS satellites;
7.3 Different Local and Remote Report types
A different report type can be specified for local reports (*PPLATSR) than that for
remote reports (*PPGPSR). The type of commands (either RAP or TAIP) which the
PinPoint accepts and the port it listens on depends on the value for *PPGPSR. For
example if *PPGPSR is set to send RAP GPS reports w/date (AT*PPGPSR=12) and
*PPLATSR is set to send TAIP reports (AT*PPLATSR=F0), the PinPoint will accept
