Chapter 1: General Information

This section provides a general description of TimeVault’s front panel input devices.  For 
details about how to enter commands and interpret display readouts, see “Overview and 
Format” on page 4-49.

TimeVault’s front panel is your primary interface with the system.  Input is through six 
keypad buttons (four directional, SET-UP and SAVE).  Output is through the two-line, 
20-character alphanumeric display (see Figure 1-1, below).  The letter at the end of the 
output date line indicates the synchronization source in use (

 for GPS, 

 for ACTS and 

 

for NTP). 

Two front panel mounted, tri-color LEDs reflect the status of TimeVault.  The system 
status indicator at the left end of the front panel has five different displays:

Possible causes and solutions for problems resulting in a solid red or solid orange display 
are discussed in “LED System Status Alerts” on page 5-89.

The connection active indicator, labeled “ACT” and located to the right of the NET Port’s 
RJ-45 plug, indicates the connection speed on the NET Port.
