4/ 8

TMS6002 is a multi-source (IRIGB or GNSS) disciplined NTP time server. It also generates a PPS output.

The equipment can be used with one source only, it is preferable to disable the unused source in that case in

order not to get the corresponding Alarms.

It can also be used with several sources with a priority selection amongst them. The equipment will

automatically switch from one to the other source if the current source is not usable anymore.

1.1. FRONT AND BACK PANEL

The front panel of the device has a high contrast LCD display with two lines of 40 characters, three color LED

indicators and a simplified 6 buttons keypad for navigation between the different screens.

Fi ure 1 – Front panel

The back panel of the equipment groups all connectors for connections to the environment :

•GNSS TNC type connector

•SD card connector

•RJ45 NTP network

•USB console

•BNC PPS signal

•BNC IRIGB IN connector

2.1. PHYSICAL INSTALLATION OF EQUIPMENT

The equipment is intended to be installed into a 9" cabinet. It is recommended to connect the equipment to

the protective ground of the cabinet via the ground stud on the left rear of the equipment.

2.2. CONNECTIONS

The following connections must to be made:

•Connect the equipment to the AC power via the supplied AC cord.

•Connect the mechanical chassis ground to the cabinet ground.

•Connect the GNSS antenna cable to the antenna input of the equipment.

•Connect the equipment to the remote management network ("LAN" connector) with a RJ45 network

cable.

Important: Power the equipment only after all connections have been made.

2.3. CONFIGURATION

The proper functioning of the equipment requires setting the configuration parameters with consistent values.

These settings are located on an SD card inserted in the back of the equipment.

The parameters available to the user are located in the 'user.ini' file. When inserted into a PC, the 'user.ini' file

is located in the 'TMS6002' directory of the SD card. On the equipment, this file is located in the '/confi '

directory.

The following table lists the parameters according to their location in the configuration space. The procedure to

change the settings is described in the maintenance chapter of this document.

Important: Please do not modify files other than those listed below under penalty of breaking the equipment’s

operation, except if the support staff of Timelink microsystems invites you to do so.

2.3.1. Gener l settings

These settings are located in the'TMS6002/user.ini' file of the SDCARD.

Only the parameters listed below can be modified, contact TIMELINK for other needs.

2.3.2. Dedic ted NTP settings

NTP authentication is managed using 3 files located on the SD card:

The file “/config/system/etc/ntp/keys” sets the keys to be used. Those keys must be shared

with the NTP client so that authentication can take place.

“keys” file example :

# Thu Apr 28 16:06:45 2016

1 MD5 12345678901234567890 # MD5 key

2 MD5 x$H;9MV>zXL7YEa%+T)x # MD5 key

3 MD5 $jHdPH(0S3Jm;A7 # MD5 key

The file “ /config/system/etc/ntp/trustedkeys” activates the keys

Example: within the following file, the 3 keys are activated

# Specify the key identifiers from /etc/ntp/keys which are trusted.

trustedkey 1 2 3

The file “/config/system/etc/ntp/restrict” define NTP server access rights for a subnet or a

machine.

Example:

restrict 192.168.10.0 mask 255.255.255.0 #authenticated or not

restrict 192.168.1.0 mask 255.255.255.0 notrust #authenticated

restrict 192.168.1.1 mask 255.255.255.255 notrust #authenticated

3. HOW TO GET STARTED

3.1. POWERING-UP

3.3. SCREENS

The display is composed of several screens on which the navigation is done by using the up and down arrow

keys. The default screen is displayed again after 5 seconds without action on the up or down arrows.

Nevertheless, it is possible to lock the display on the current screen by pressing the green button.

No configuration changes can be made from the screens displayed.

The following sections describe the contents of screens.

3.3.1. MAIN SCREEN

This screen is displayed as the default screen. It provides a synthesis of the operation of the equipment.

The displayed information is the following:

•current UTC date and time

•name of the selected time source (GNSS or LOCAL)

•quality of the generated time

•quality of the frequency stability

Time 2014-04-25 12:00:00 UTC Freq

▌▌▌▌▌ Synced to source GPS ▌▌▌▌

Screen sample

The quality indicators are made of 0 to 5 bars.

Time indicator:
