6 NTP Software Installation and Configuration
6.3.1 GPS Preparation
• Perform the checkout, installation and connection
instructions in chapters 1–4.
!
Note – Temporary installations, as described in Chapter 2, can be
used to establish functionality of NTP, but reliable performance
cannot be achieved until the Acutime smart antenna is properly
installed with clear view of the sky.
• The Acutime and Synchronization Interface Module should
be powered up.
• PPS indicator LED should be flashing once per second,
indicating the output of data packets.
• A valid UTC almanac has been acquired by the Acutime
Smart Antenna. This should be confirmed using the Acutime
Monitor or TSIPCHAT applications.
!
Note – NTP will not accept time stamps from the Acutime NTP
reference clock until a valid UTC almanac has been obtained. The
UTC information is stored in non volatile memory and only erased
during a factory reset operation.
