TCXO AND RTC CIRCUIT 

The Display contains a 

RTC (Real Time Clock)

 circuit allowing 

the clock to maintain an accuracy of ± minute per year to 
the last known  NTP input  (± 165 mSec per day) when NTP 
is not present or cannot be decoded (i.e. freewheeling 
mode).     

 

MAINTENANCE-FREE RECHARGEABLE BATTERY 

The RTC is maintained continuously from a rechargeable 
battery circuit during periods of power outage.  Minimum 
holdover period is two weeks with a fully-charged battery 
under constant drain. 

 

DEFAULT CONFIGURATION 

The factory defaults may be restored by using the 

WinDiscovery

 program, 

Telnet

 or by using the reset button 

at the rear of the NTDS-A.  

Your Masterclock display ships from the factory with the 
following configuration as defined below. The NTDS-A 
firmware interprets incoming time signals as UTC.
