This chapter describes the function principle of the Time Server 8029NTS/GPS and the
internal relations between the different functional groups.

Block Diagram
•
Internal Supply Voltage
The individual functional components are supplied with the required operating voltage
via the implemented power supply unit.
•
Firmware Update
A H8 firmware update of the Sync Souce (here Module 8024GPS) is completey
controlled by Module 8029NTS.
The update file for Module 8024GPS is loaded into Module 8029NTS via LAN through
the WebGUI. Then Module 8029NTS performs the update of the Sync Source (here
Module 8024GPS) independently.
•
Management
The entire control of the Sync Source (here Module 8024GPS) is done by Module
8029NTS. All data of the Sync Source, indicated via WebGUI, are demanded cyclically
by Module 8029NTS from the Sync Source (here Module 8024GPS) or if necessary.
These data are then prepared for the display in WebGUI. After activation settings for
the Sync Source are transferred to the Sync Source immediately.
•
High Precision Time
The Sync Source provides a high-precision time information and the according
synchronization status to Module 8029NTS. This time and status information is used
for synchronization of the NTP service and if applicable other signal generations
running on 8029NTS.
