2 Safety Instructions for Building-in Equipment
This building-in equipment has been designed and tested in accordance with the requirements of Standard
IEC60950-1 "Safety of Information Technology Equipment, including Electrical Business Equipment".
During installation of the building-in equipment in an end application (i.e. rack) additional requirements
in accordance with Standard IEC60950-1 have to be taken into account.
•The building-in equipment is a class 1 - equipment and must be connected to an earthed outlet
(TN Power System).
•The building-in equipment has been evaluated for use in office environment (pollution degree 2) and
may be only used in this environment. For use in rooms with a higher pollution degree more stringent
requirements are applicable.
•The building-in equipment may not be opened.
•Protection against fire must be assured in the end application.
•The ventilation opening may not be covered.
•The equipment/building-in equipment was evaluated for use in a maximum ambient temperature of 50◦C
(40 ◦C by using Rubidium).
•For safe operation the building-in equipment must be protected by max 16 A fuse in the power installation
system.
•Disconnection of the equipment from mains is done by pulling the mains plug.

3 Global Information LANTIME M400/GPS
The LANTIME (Local Area Network Time Server) provides a high precision time base to a TCP/IP network
(Stratum-1-Server). The NTP (Network Time Protocol) is used to synchronize all NTP clients with the refer-
ence. The several LANTIME variants differ from each other by the time reference and output configuration. A
GPS or GNSS (GPS, GLONASS, Galileo, BeiDou) receiver, GNS-UC (only GPS and Galileo) , a long wave
receiver (like DCF77, MSF or WWVB) or an IRIG time code receiver can be integrated as an internal reference
as well as a combination of these references (hybrid system). External references are also possible.
The LANTIME system is a set of equipment composed of an integrated GPS receiver, a single-board com-
puter and a power supply, all installed in a metal 19 inch modular chassis and ready to operate. A simplified
LINUX operating system is installed on the single-board computers flash disk. Eight push buttons and a display
can be used to configure and monitor the time server.
After the network connection has been established the time server can also be configured and monitored
remotely from a workstation via TELNET or FTP. An integrated web server enables access to the LANTIME by
using an ordinary web browser.

1. The main menu is displayed after switching on the
device and having completed the initialization phase.
In the main menu the most important status informa-
tion are displayed. In the top line of the display the
operating mode of the reference clock / reference time
is shown. Instead of "GPS: NORMAL OPERATION"
the messages, "GPS: COLD BOOT", "GPS: WARM
BOOT" or "GPS: UPDATE ALMANAC" can appear (as
GPS reference Time). In case the antenna connection
is interrupted, the following message is shown: "GPS:
ANTENNA FAULTY".
