SST4 Series  SATELLITE SYNCHRONIZED TIME   NTP STRATUM 1

The SST4-SO NTP server provides UTC (Coordinated Universal Time) to IT and Telecommunication Systems. This information is generated by the U.S. Naval Observatory and retransmitted by GPS satellites. Up to 12 satellites are tracked simultaneously. All pertinent data are stored in solid state memory providing a history log in excess of nine years. Three front panel LEDs provide instant status of power and activity. Although not as accurate as the SST2, the SST4 series serves the Small Office/ Home Office needs.  Included with each unit is an active antenna with 25’ of cable and a 12VDC power supply.
