Front Panel Interface Chapter 1: General Information
1.12 Front Panel Interface
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 (
G for GPS, A for ACTS and N
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.
