Synchronizing the SM45 Real-time Clock
The SM45 features a battery-backed real-time clock for accurate date-time stamping of all
alarms and control processes. Battery back up ensures that the date and time is maintained
while the SM45 is not powered.
The real-time clock is set to Coordinated Universal Time (UTC) during manufacture. If
required, the time can be corrected by synchronizing it with the internal UTC time of your
PC.
PC real-time clocks are not always accurate. Ensure that the time of your PC is correct before
synchronizing.

1 Ensure that the SM45 is powered and connected to DCTools.
2 From the DCTools System Summary (Home) screen, click the Configuration
hotlink and
then Identity
to display the System Identification view.
3 Under Time Synchronization, click the Synchronize button to synchronize the real-time
clock.
