How to set up a custom time server

In order to use a custom time server, a PC needs an NTP service.

Important:

Please note in case of using a Microsoft Windows operating system:

Since professional Edition, Windows operating systems offer an integrated NTP service. Unfortunately, this internal NTP service provided by Microsoft Windows is not compatible for using with CS141.

Numerous freeware tools located on the Web, which can provide this service, too - therefore it is not necessary to use Microsoft's internal NTP service.

A well-made tool is NTP for Windows, which we use as an example in this manual. Due to the fact this is a freeware tool, the download source may differ after writing this tutorial.

Step 1: 

Download the tool from the Internet:

Possible download sources would be

Please note, download links may differ and even change after writing this tutorial.

After downloading, the tool can be easily installed.

Step 2: 

Start the installation routine. The installer guides you through the complete installation:

Please note that the functions selected in this example may not necessarily be suitable for your network. If in doubt, consult your system administrator for the correct settings.

NTP Tool needs an account to provide time services – Normally you can use this option:

•  Use SYSTEM Account

The tool asks to create a configuration file during installation. This is necessary for operation therefore you need to allow it - the tool will create and configure this file for you.

Note:

After installation, you should restart NTP for Windows using the option Start as administrator. Otherwise, it could cause problems during operation. If you are not authorized to use this option, please contact your local system administrator.

Testing the NTP server tool

If the NTP server has started, you can check the functions with an NTP server testing tool. Download another freeware tool from the following website:

http://www.ntp-time-server.com/ntp-server-tool.html

Please note that this tool only returns correct values ​if the following 2 conditions are completed:

1. The computer with the NTP time server is in the same network segment like the computer containing the NTP testing tool.
2. You use a second computer for testing

The NTP server in this example is installed on a Windows machine dealing with the IP 192.168.200.17, subnet mask 255.255.255.0. Both the test PC and the CS141 must therefore be located within the corresponding IP address space.

Otherwise, the NTP server service will not work.

Set up time manually

Manually setting the time adjusts the internal clock to your specified time. When you click "Set System Time", the CS141 applies the entered values and displays them directly under "Current System Time".

Note:
Synchronization with a time server is handled automatically by the CS141’s operating system and is therefore not recorded in the log files. The message “Device time synchronized” in this case refers to a special UPS function – it means that the CS141 has adjusted the internal clock of the UPS.

Exception:
You have changed the settings and manually restarted the NTP service using the “Synchronize with Time Server” function.
