The package contents for the ELETECH NTP-100 are:

The indicators for the LED lights on the top panel of the ELETECH NTP-100 are as follows:

Connect the ELETECH NTP-100 to the network as shown in the connection diagram.

In order to obtain time from the ELETECH NTP-100, the PC needs to have the NTPClock client software installed.

1. Insert the installation CD and open the NTP Clock folder. Double-click setup.exe. The following dialog box will appear:

4. NTPClock is installing..

5. Click Close to finish the installation.

6. After installation, a NTPClock icon will be created on the Windows desktop.

7. Execution of the NTPClock program requires administrator privilege. If you are not logged in as administrator, you must do the following:

Right click on the NTPClock icon and select Properties.

When the following dialog box opens, select the Compatibility tab. Check the box for “Run this program as an administrator”, then click OK.

8. Double-click the icon and a clock icon will appear:

A red clock indicates that the PC has not linked with the ELETECH NTP-100.

A yellow clock indicates that the PC has linked with the ELETECH NTP-100 but the GPS is not working properly.

A white clock indicates that the PC has linked with the ELETECH NTP-100 and the GPS is working properly.

9. Right-click the clock. The following dialog box will appear:

SNTP Client Settings

Actions

SyncInterval: The time synchronization interval between the PC and the ELETECH NTP-100. Default is 3600 second (1 hour), minimum setting is 1 second.

UpdateLocalDateTime: If set to False, time synchronization will be disabled but the color of the clock will remain white as long as the PC can maintain communication with the ELETECH NTP-100.

Connection

RemoteSNTPServer: Enter the IP address and port number of the ELETECH NTP-100.

Timeout: If the PC fails to get a response from the ELETECH NTP-100 within this period then the color of the clock icon will turn red. The default is 5000 milliseconds (5 seconds).

VersionNumber: The Internet Protocol Version to be used. Version3 is for IPv4 and Version4 is for IPv6.

To stop communication with the ELETECH NTP-100, double-click the clock icon and quit the NTPClock program. Time synchronization will also be stopped.

Power up the ELETECH NTP-100, the following screens will appear.

The ELETECH NTP-100 has a default IP address of 192.168.1.100. This IP address must be changed if it’s not in the same subnet as the LAN where the device is to be installed.

The first step is to change your PC’s IP address to 192.168.1.xxx, so that you can log in the ELETECH NTP-100 and change its IP address. If you are not sure how to change your PC’s IP address, please consult with your IT personnel.

Device Login

1. On the web browser, type the ELETECH NTP-100’s IP address and press Enter.

2. Enter user name (default = ntp100) and password (default = 1234) then click OK.

The following screen will appear after logging in:

Eletech NTP Server Setup

IP: 192.168.1.100

Net Mask: 255.255.255.0

Gateway: 192.168.1.1

HTTP Port: 80

NTP Port: 123

Time Adjustment: 1150

DNS: 8.8.8.8

Password: ….

Time Zone: 480

Save

click “Save” button to save and reboot device.

IP Address (IPv4)

The factory default value is “192.168.1.100” which needs to be changed if it is not in the same subnet as the LAN where the device is to be installed.

Net Mask

The default subnet mask is “255.255.255.0” which works well in most cases.

Gateway

The gateway address should be set to the router’s IP address. Consult with your IT personnel if you are not sure.

Http Port

The port 80 is standard port used and recommended for most installations.

NTP Port

The port 123 is standard port used and recommended for most installations.

Time Adjustment

The ELETECH NTP-100 has a backup clock that’s used to keep time when GPS signal is lost. When GPS signal resumes the backup clock is automatically calibrated by GPS, if necessary. Should GPS signal be lost for a long time, the backup clock may need to be manually calibrated by changing the Time Adjustment value. Default setting is 1150. Increase the value if ELETECH NTP-100 runs too fast, or decrease the value if ELETECH NTP-100 runs too slow. A value change of 50 will result in a time change of 0.438 second per year.

DNS

Please leave it unchanged.

Password

Changing the password is recommended.

Time Zone

Enter an offset value (in minutes) based on your time zone. For example, the time zone for Singapore, which is 8 hours east of UTC, has an offset of +480.
