1 Introduction
The GPS-2-E-NTP Network Timeserver provides a high precision time directly to TCP/IP
networks using NTP (Network Time Protocol). It synchronizes time of any NTP clients
running on remote PC’s. It supports both NTP and SNTP clients for more of current popular
operating systems including: Microsoft Windows 95/98/Me/NT/2K/XP, Linux, FreeBSD,
IBM AIX and other UNIX family systems. It can synchronize simultaneously thousands of
servers, workstations and routers.
The high precision UTC time is powered by cesium atomic clocks coming via GPS (Global
Positioning System) satellite system. The independent GPS antenna can be connected optionally
too. Both antennas works redundant.

The GPS-2-E-NTP distributes UTC reference time to 1 Ethernet 10/100Mbs sub-network. All
time and satellite information is traced on front panel 2 isolated LCDs. More detailed statistic is
available by remote NTP software: SNTP Manager for Microsoft Windows 2K/XP.
The installation of GPS-2-E-NTP timeserver is very easy. It simply requires basic TCP/IP
address (IP, MASK, GATEWAY) to be set up by ordinary terminal program (e.g. Windows Hyper
Terminal). This software can be executed on any remote PC connected to GPS-2-E-NTP via
Ethernet 10/100Mbs sub-network.
