Frequently Asked Questions
What is the difference between an SBT clock and an SBTG clock?
The SBT digital clock operates in the 900MHz frequency range, while the SBTG operates in the 2.4GHz
frequency range. Clocks of different frequency ranges cannot be used together in the same system.
Can this digital clock be used as a standalone clock?
The 3300 digital clock can be used as a standalone clock, but it will not keep synchronized time in this
configuration. Instead, it will rely on an internal quartz oscillator for keeping the time. The clock will drift by
a few seconds each year while in this mode, and will need to be readjusted manually.
How can I use this digital clock with Rauland, Dukane and other systems?
3300 clocks can be added directly to several sync wire systems. Refer to the Inputs section of this manual
for instructions on how to connect the clock to each system type.
3200 and 3100 clocks can obtain time from these systems through a master clock working as a translator.
Data from the other system would be sent to the master clock, and then the master clock would send the
data to the digital clocks through 2-wire, RS485, or wireless communication protocols.
What happens to the digital clock if a power failure occurs?
If a power failure occurs, the display will shut off but the clock will continue to keep time with its internal
quartz oscillator. This oscillator will continue to run on a tiny battery backup for about ten years. In this
mode, it may drift from synchronized time by a few seconds for each year that the clock is without power.
Once power is restored to the clock, the display will turn on and display the time on the quartz oscillator. It
will correct this to accurate, synchronized time once a signal from a master clock is received.
What happens to the digital clock if contact with the time data source is lost?
The digital clock will rely on an internal quartz oscillator for keeping the time until time data is received.
The clock will drift by a few seconds each year while in this mode, and will need to be readjusted manually.
The 3300 digital clock is able to act as a master clock. If the communication input is lost to the 3300, and
the 3300 is acting as a master, then the clock will send synchronization data to any clocks down the line
that are connected. This data will be based off of the 3300’s quartz oscillator, so while the clocks will be
synchronized to each other, they may not be showing accurate time. Colons will blink if the clock has not
recieved a signal after a set amount of time.
How do I take advantage of the 3200/3300 chronograph functions?
The Chronograph functions can be engaged through Sapling’s Elapsed Timer (part# SBD-ELT-001-0), or by
using a dry contact closure with the configurable user inputs (3300 only). Refer to the respective selections
of this manual for setup instructions.
How can I display “BELL” and “FirE” on the clock?
“FirE” and “BELL” are signals sent by the appropriate master clock. Refer to the master clock manual
for instructions.
