Master Clocks
SMA 2000
Sapling’s new SMA 2000 series master clock enables a user to have complete flexibility over their system. The SMA 2000 comes standard with (S)NTP capability for synchronization to pre-programmed (S)NTP web servers. The clock has two pre-programmed relays that are dedicated for synchronous wired clock systems. The master clock can be purchased with a built-in transmitter for sending out the signal wirelessly to Sapling wireless analog and digital clocks. A GPS can be added as a supplement to the already feature-rich clock for even more accurate timekeeping.
SMA 3000
Sapling’s new SMA 3000 series master clock comes fully equipped with a crisp LED readout and a backlit two line LCD display. Programming the SMA 3000 with up to 800 events is easy with the 2X8 rubber tactile keypad. The SMA 3000 comes standard with (S)NTP capability for synchronization to any (S)NTP web site. The clock has two pre-programmed relays that are dedicated for synchronous wired clock systems.
The master clock can be purchased with a built-in transmitter for sending out the signal wirelessly to Sapling wireless analog and digital clocks. A GPS can be added as a supplement to the already feature-rich clock for even more accurate timekeeping. The SMA 3000 Series also encompasses a fully functional web interface for controlling the master clock from any computer on a network or via a crossover cable.

SAPLING SMA MASTER CLOCKS
Sapling is proud to introduce its SMA Series Master Clock. The standard models come loaded with many helpful features including a user friendly built-in web interface for master clock settings and monitoring, as well as many optional features to choose from, allowing system flexibility all wrapped in an elegant and stylish housing.
Sapling’s Master Clock is the center of a synchronized clock system. The master clock’s primary function is to receive accurate time and distribute that time to all of the secondary clocks and other devices throughout a facility. The master clock is programmed to frequently send out a time signal in order to prevent the clocks from drifting. This will allow all of the secondary clocks in the facility to always display the same time on every clock within a system.
How Does the Master Clock Receive Time?
The master clock can receive the accurate time mainly from two sources:
- NTP Server – A standard feature in each and every master clock model
- GPS Receiver – An optional feature
The master clock can also receive the time from:
- Once-a-day contact closure from a third party device
- May interface with existing clock systems (58 minute or, 59 minute protocol, National Time / Rauland or Dukane protocol)
Additionally, the master clock has its own internal real-time (quartz) clock. In the event that communication with the accurate time source has been lost, the system will still be synchronized based on the real-time (quartz) clock, until communication with the accurate time source has been restored.
RECEIVING ACCURATE TIME FROM AN NTP SERVER
All Sapling Master Clocks receive accurate time from NTP servers as a standard feature. A master clock may receive its time either from an external NTP server (third party NTP server) or via an in-house NTP server (if there is one in the facility).
Receiving Accurate Time from Third Party NTP Servers:
Sources of NTP time include government facilities, colleges and universities, and various corporations. Such institutes allow a free connection to their NTP server via the Internet as a source of accurate time. Sapling Master Clocks are designed to store up to 10 NTP server IP addresses for redundancy. This mean that if communication with the first NTP server has been lost, the master clock will automatically attempt to receive accurate time from the next NTP server in the list. This unique feature provides reliability and redundancy to the system. Sapling already provides the master clock with 10 NTP server IP address inputs to get accurate time from, but at any time you are able to change all 10 default NTP server IP addresses to ones that you prefer.
Receiving Time from an In-House NTP Server:
Some facilities already have their own in-house NTP server. In this case, the in-house NTP server IP address should be set in the Sapling Master Clock so it will refer to this in-house NTP Server and receive NTP time via LAN connection. In addition, there are still 9 other NTP server IP addresses that can be stored forbackup and redundancy.
Relaying Time to Secondary Clocks
One of the functions of a master clock is to relay accurate time to the secondary clocks in the system. A master clock can relay time to the secondary clocks in the system either via wires or in a wireless manner. Sapling offers different types of clock systems, some of which are wired and some are wireless. While all of Sapling’s Master Clocks can relay time to the secondary clocks in a wired manner, a master clock with a wireless transmitter is needed for wireless clocks. All Sapling Master Clock models are offered with or without transmitter. Master clocks with a transmitter will support both wired and wireless clocks, while a master clock without the transmitter will only support wired clocks.
