 1  Introduction

The Time Machines PTP Network Time Server is a simple to use GPS sourced time server that will 
supply accurate time for all computers and time keeping devices on the network.  By placing a time 
server on the local network, PTP and NTP time packets are provided without requiring systems to go to
the Internet to get a Stratum 1 time synchronization.  The system uses an active GPS antenna to 
maintain the current time as broadcast by United States GPS satellites.  With this device installed on 
your local network, there is no longer the worry that if the Internet connection goes down, time 
synchronization is lost across the network.  In addition, the TM2000A includes a high precision internal
clock based on an OCXO (Oven controller oscillator) that allows the unit to serve accurate time beyond
loss of the GPS antenna signal.
The unit is small and can be placed anywhere within the network layout.  The built in high sensitivity 
GPS receiver is able to lock multiple satellites from within many buildings or from a window location, 
removing the requirement that outdoor antennas be installed.
Setup and use of this time server is straightforward.  Simply connect both the included power supply 
and the GPS antenna to the base unit and then connect the base unit to the local network.  Go to a 
computer on the network and browse to the device at its default address to enter the software setup 
within the control box.  Set parameters to match your network and the system will start to send out time
packets to any device on the system that asks for an update from it.     Two servers can be setup to 
provide redundancy and more capacity.
When paired with our digital Power Over Ethernet (PoE) or WiFi clocks, synchronized time is assured 
no matter the state of your network, or the state of the internet time server the clocks are pointed to.  
Accuracy is also improved because the network delay of the internet is highly variable, while the local 
LAN connection is likely sub-millisecond delay.
TimeMachine GPS based time servers are suited to any application where coordination of events at 
multiple locations is required.  Without coordinated network time, searching for problems across 
multiple system logs becomes much more difficult.  Education, industrial facilities, military 
installations, public safety command rooms,  government, broadcasting, and hospitals are all candidates
for synchronized time systems.
