Page 4: Introduction
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. -

2 Installation 2.1 Location To receive GPS signals the Time Server's antenna must be located in a location where it can “see” the sky. The GPS module itself is highly sensitive and able to “see” the GPS satellite signals from within many structures. -

It is also possible for the LOCK LED to turn off, or blink, after a GPS timing lock has occurred and the SEC LED continues to blink. This signifies that the TM2000A has an accurate internal time and is serving time, but is trying to re-establish the timing lock because it was lost for some reason. -

3.3 Settings Page 3.3.1 TM2000 Name This is a generic entry that has no effect on the TM2000A operation other than to allow the user to enter a name for the device to help recognize it when parameter updates are required. -
Page 8: Ip Address
The Password of the unit can be changed in this field. The existing password is not displayed for security purposes. Enter the new password and click the “Change Password” button to update. The TM2000A will then prompt for the new password to be entered to continue access to the web pages. * Default Username/Password is “admin”/“tmachine”. -
Page 9: Status Page
3.4 Status Page The status page is an information only page. It shows the various pieces of information about the current working state of the device. 3.4.1 Location Location shows the latitude and longitude of the device itself based on the GPS receiver. Paste this set of coordinates into Google Maps to see your location. -
Page 10: Gps Fix
3.4.4 GPS Fix This displays the level of the current GPS lock. No GPS Fix – Check cable connections. If connected correctly, likely the antenna needs a better view of the sky. Obstructions, building materials, window tinting can all cause possible signal issues. 2D - GPS satellites found. -
Page 11: Update Page
3.5 Update Page The update page is used to update firmware of the unit. The firmware updates will be archived and available for download from the timemachinescorp.com website. Save the file to the local computers drives. Most likely the file will need to be unzipped. The file type that is used for the update is a .img file. -
Page 12: Diagnostics Page
HTTP download. The binary log can be used by TimeMachines as an aid in troubleshooting. 3.6.3 Reboot System Clicking the Reboot button will cause the TM2000A to do a software based reset. This is a full kernel reset of the unit and takes 20-30 seconds to complete. -
Page 13: Ntp/Ptp Settings Page
3.7.2 Allow 2D Fix for NTP This checkbox will allow the TM2000A to start serving time once a 2D lock is achieved by the GPS receiver. It is generally better to get a 3D lock as timing accuracy is much better. The GPS module maker doesn't guarantee accuracy until a 3D lock is achieved, but this option exists if needed. -
Page 14: Disable Holdover Limit
3.7.3 Disable Holdover Limit When checked, this option allows the holdover limit of the device to extend forever. The TM2000A requires a GPS lock to initially set its time, but by checking this option, it can then be run without a GPS lock. -
Page 15: About Page
The front panel button, accessible with a paperclip or other small object, accessible from the front panel of the TM2000A is used to reset the units software settings to factory original. This is useful when a password is forgotten or the IP address cannot be determined. To do this, insert a paperclip or ball point pen end through the hole in the front of the unit until you feel the button depress. -
Page 16: Locator Data Query
Starting in version 0.3.3, the Locator service employed by TimeMachines clock products is also included in the TM2000A. This makes it easier to manage and monitor a time system on a local network using the TM-Manger software. See the TM-Manager documentation for more information on this feature. -
