Sapling’s new SMA 2000 series (SMA-2R0-1000-1) master clock is rack mountable and enables a user to have complete flexibility over their system. The SMA 2000 comes standard with SNTP capability for synchronization to pre-programmed SNTP 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.
