iSIC Data Logger:
The general tab allows you to see basic iSIC information such as the iSIC time, battery voltage,
and firmware version as well as much more. Most items can be updated by putting a check in
the box next to them and, if needed, entering new information. Click Apply for the readings to
take effect.
Sync to PC time: Check this box if you notice that the iSIC Time is not the same as your
computer clock
Change address: Changes the iSIC address. This should only be done on 4100-iSICs. Note, no
two 4100-iSICs should have the same address. As each iSIC ships with address 1, it is important
to change the address when using more than one iSIC.
Change Protocol: Changes the type of iSIC an iSIC thinks it is. Use this only under NexSens
direction.
Reset all to mfg default: Requires NexSens assistance. Usually never required.
The main battery voltage needs to be above 10.7V for the iSIC to operate. For 4100-iSICs, the
iSIC will stop communicating at 11.5V. This is a feature designed to conserve battery life. The
iSIC will continue to log sensor readings until the battery is charged above 12V. No data loss will
result in this loss of communication.
The RTC (Real Time Clock) Battery voltage should typically range from 2.7 to 3.3. When the
battery voltage drops below these levels dramatically (approaching zero volts), the iSIC will not
hold a time whenever the iSIC is powered down. This means that every time the iSIC battery is
disconnected, the iSIC time will reset. The iSIC cannot log data when the time resets.
Note: An iSIC with a dead RTC battery will need to be returned to NexSens for a replacement.
