5. Apply power by inserting the power supply module into an appropriate AC power source and the power connector into
the male Switchcraft-style locking power socket on the rear of the unit (labeled
DC IN
).
6. If desired the unit can be operated from a nominal 12 VDC battery (9-18 VDC range). Observe voltage polarity as
indicated on the rear panel (the center pin is positive +VDC, and is labeled 9 -28VDC).
7. When power is first applied the initial sequence of the front panel LED is:
•
amber and green LEDs on briefly, with time display showing 88:88:88
•
all LEDs extinguish briefly
•
amber (NTP) LED out, green (Status) LED steady on
•
green (Status) LED begins twice per second blink, with time display incrementing the seconds digit once per second
(indicating locked to internal TCXO oscillator , and acquiring lock to an external source, if applicable).
•
Green (Status) LED begins to blink once per second and time display increments the seconds digit once per second
when synchronized to an external reference source, if applicable.
[Note: when configured to obtain network configuration through DHCP, the display may hesitate on startup
while DHCP is resolved.]
At this time the NTP100 can be communicated with over the local network using the WinDiscovery application.
WinDiscovery can find and identify the NTP100 through the exchange of broadcast messages even when TCP/IP
networking parameters are not configured on the same network.
Once the NTP100 has a valid network configuration it can also be accessed via Telnet by computers in the same
logical network.
