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 SNTP capability for synchronization to any SNTP 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.
