3.4.2 iSIC Power Management
By default, all iSIC‟s are set to continuously power telemetry such as a spread spectrum radio or
cellular modem. However, in battery powered applications where limited solar charging is
available or the current consumption of sensors is high then it may be advisable to use a power
schedule.
Power schedule allows you to set when the iSIC telemetry will be powered on, and when it will
be powered off. This feature is useful for 4100-iSIC, 3100-iSIC, and 4200-iSIC models and is not
used in direct connect, analog phone line, or stand alone systems.
Select the iSIC you would like to setup power management for in the Navigation Panel. Then
click the Setup button and go to the Schedule tab. At the bottom of the window there is a
Switched Power Schedule section.
You have three options for power management. Continuous, Fixed time, or Periodic.
 In continuous mode operation the iSIC will be powered on continuously
 In fixed time mode the iSIC will only power on at the set time and will turn off after the
duration has expired.
 In periodic mode the iSIC will turn on at every interval for the specified duration.
Note: you will be unable to communicate to the iSIC during the times that it is powered off. It is
recommended that you also set a “Sync RTC Schedule” to make sure that the iSIC clock matches
the PC clock at all times, ensuring you that you know when it is on or off.
Note: If you are using power schedule and the iSIC is scheduled to be off but you need to talk to
it you can do so by cycling power. After cycling power you will have five minutes to change the
power schedule if you would like.
