9. Re-configuring Cellular Phone On/Off State
This Motorola Cellular Phone is equipped with a feature known as
Convenience On/Off state. When the phone is turned off it saves certain
parameters to non-volatile memory so that they may be remembered when the
phone is turned back on. This includes the on or off state of the phone at the
time the ignition sense line (green wire) was set low (0V).
In unattended installations the datalogger will NOT power up the cellular
phone if the red LED power indicator/switch has been manually turned OFF
(no longer lit) while under datalogger control. There is a specific sequence that
causes this failure to happen:
1. Primary +12VDC Power has been applied to the phone.
2. The ignition sense (green wire) is set high (5V) via a control port.
3. The red LED power indicator/switch has been manually depressed to turn
the phone off (LED is no longer lit).
4. The ignition sense line is set low (0V) via a control port (stores phone’s
OFF power state to non-volatile memory).
In this configuration the cellular phone will remain off even if the control port
is set high again. The only way to turn the phone back on is to manually
depress the red LED switch again.
Campbell Scientific has configured the phone at the factory to power-up under
datalogger control. If your cellular phone is not turning on while under
datalogger control, you will have to restore the phone’s “ power on” state in
non-volatile memory.
