Page 16: Function Principle
UNCTION RINCIPLE Function Principle This chapter describes the function principle of the Time Server 8030NTS/GPS and the inter- nal 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.
Page 17: Function 8030Nts (Webgui: Device)
RINCIPLE Function 8030NTS (WebGUI: Device) The Module 8030NTS is the "heart" of the Time Server 8030NTS/GPS. A complete LINUX operating system is running on this Module providing all functions such as NTP, WebGUI etc. The Module also controls the connected Sync Source (here Module 8024GPS). Using the high-precise time information of Module 8024GPS the NTP service running on Module 8030NTS is also adjusted with high-precision.
Page 18: System Behaviour
This chapter describes the behaviour of the system in special operational phases and condi- tions. Boot Phase The boot process of the Time Server 8030NTS/GPS starts after turning on the system or a reset. During the boot process the Module 8030NTS boots its LINUX operation system and is there- fore not available via LAN.
Page 19: Firmware Update
EHAVIOUR Firmware Update The Time Server 8030NTS/GPS is a multi processor system. For this reason a firmware up- date always consists of a so called Software SET including up to three (3) program releases defined by the SET version needed to be loaded into the board.

Page 25: Voltage Input / Fuse Protection
Further equipment protection is not required because the device is fused internally. Recommended External Fuse When connecting the Time Server 8030NTS/GPS a suitable fuse protection of the power sup- ply needs to be observed. Accordingly, the performance data should be taken from the nameplate of the device. Cur- rently the standard versions of the Time Server 8030NTS/GPS are supplied with power sup- plies with power consumption between 6 and 15VA.
Page 26: Power Supply Unit Specifications
All specifications regarding the DC power supply can be found in Chapter 11.4 Power Sup- plies. 5.3.2.2 Fuse Protection When connecting the Time Server 8030NTS/GPS a suitable fuse protection of the power sup- ply needs to be observed. Accordingly, the performance data should be taken from the nameplate of the device.

Restarting NTP services is the only possibility of making NTP changes effective without having to restart the entire Time Server 8030NTS/GPS. As can be seen from the warning message, the currently reachable stability and accuracy get lost caused by this restart.

Page 76: Symmetric Key
The keyword key of a client’s ntp.conf determines the key that is used to communicate with the designated server (e.g. the Time Server 8030NTS/GPS). The key must be reliable if time is to be synchronised. Authentication causes a delay. This delay is automatically taken into account and adjusted in the current versions.
Page 77: How Is A Key Created
The receiver (which has the same key) carries out the same calculation and compares the results. Authentication has been successful if the results agree. GPS - NTP Time Server with 2x 10/100/1000 MBit LAN Interface 8030NTS/GPS - V04.00 77 / 141...
