Standalone Logging Power Management

In VehicleScape DAQ the Standalone Logging feature has important Power Management settings to control when the logger will go to sleep and wake up.  These power mode settings apply to all Standalone Logging collections.

ICS loggers (neoVI FIRE, PLASMA, ION) are designed to be "always on", which means they do not have power on/off switches.  Various sleep and wake up settings are available to minimize power consumption while connected to power.  It is CRITICAL to change the default Never sleep setting to avoid killing a car battery!

Refer to Table 1 which describes the settings in Figure 1.

Table 1: Standalone Logging Power Management Settings

Power Management Setting Description
Disable all logger Tx'ing on this For all collections, stop all diagnostic transmit messages sent by the logger after the chosen expression becomes true.
Never For all collections, use default firmware settings configured in hardware with neoVI 3G Explorer.

The firmware default for all ICS hardware is Sleep Mode DISABLED, which means never enter sleep mode...always stay awake.  This setting can kill a car battery if used incorrectly.
When Message Not Present For all collections, go to sleep after a chosen message is not received for a chosen period of time.
On Expression For all collections, go to sleep after a chosen expression is true for a chosen period of time.
On No Bus Activity For all collections, go to sleep after all chosen networks connected to the logger remain quiet for a chosen period of time.

Networks are chosen by clicking Advanced Options in the Standalone Logging Generate section.
Time Period For all collections, the length of time to wait (in seconds) before going to sleep.
Normal Wakeup For all collections:
  • When awake, everything runs.
  • When asleep, the wakeup might not log the first few messages.
This mode has the lowest current draw while asleep when compared to Instant and Drowsy modes.

Any activity on any network connected to the logger will trigger a wakeup and keep it awake until sleep conditions are met again.
Instant (HS/MS) Wakeup For all collections:
  • When awake, everything runs.
  • When asleep, a wakeup from HS or MSCAN can log the first message that woke it up.
This mode has higher current draw while asleep when compared to Normal mode.

Any activity on any network connected to the logger will trigger a wakeup and keep it awake until sleep conditions are met again.
Drowsy Wakeup For all collections: (intended for neoVI PLASMA)
  • When awake, the touch screen remains off, but the script and SD card still run.
  • When asleep, a wakeup from HS or MSCAN can log the first message that woke it up.
For neoVI PLASMA, this mode has the lowest current draw while AWAKE when compared to Normal and Instant modes.

Any activity on any network connected to the logger will trigger a wakeup and keep it awake until sleep conditions are met again.
Start a new file when waking up For all collections, start a new log file after each wakeup instead of appending data to a previous log file.
neoVI PLASMA remote wakeup For all collections, allow a sleeping PLASMA to be woken up with an SMS text message.
3G Use the PLASMA 3G wireless link to upload all log files to a WirelessNeoVI server before going to sleep.  (slower than WIFI, but usually more available in the USA)
WIFI Use the PLASMA WIFI wireless link to upload all log files to a WirelessNeoVI server before going to sleep.  (faster than 3G, but not as widely available in the USA)
Fail Timeout For all collections, PLASMA will automatically upload all log files to a WirelessNeoVI server before going to sleep until it is successful or until this timeout (in minutes) expires.  This timer is reset after each PLASMA wakeup.
