How to do SNTP time synchronization of a PCD within a LAN without internet access (FAQ #101884)
A Windows PC (or Windows Server) can be configured as an NTP server.
The PCD's can read the time via SNTP from this NTP server.
The clock of PCD's, located in a LAN without internet access should be synchronized over SNTP.
If there is a PC on the same network, then this PC could be used as SNTP Server for the PCD's.
The PCD's could read the time via SNTP from this NTP server.
In the Device Configurator, the IP address of the NTP Server (Windows PC or Windows Server) must be defined as SNTP server.
Configuring a PC (or Server) as NTP Server:
Instructions for: Windows 2000; Windows XP; Windows Server 2003; Windows Server 2008 (32-bit)
1 Open the registry editor with "Start -> Run... -> regedit". 2 Search for the code
3 Edit the "LocalNTP" value and set it to 1.
- If the "LocalNTP" value does not exist in your system, create a new DWORD value.
- 0 means deactivated, 1 means activated.
4 Restart the computer to make the changes effective.
Instructions for: Windows 7 (32-bit & 64-bit); Windows 2008 Server R2 (64-bit)
1 Stop the "Windows Time" service under START > Control Panel > System and Security > Administrative Tools > Services. 2 Open the registry editor with "Start -> Run... -> regedit". 3 Search for the code
4 Set the "Enabled" value to 1 5 Search for the code
6 Set the "AnnounceFlags" value to 5 7 Start the "Windows Time" again and set the start type to "Automatic" if not already done.
Changes in the Registry can lead to unexpected problems requiring you to reinstall your system.
We cannot guarantee that problems arising from changes in the registry can be solved.
Changes in the Registry are entirely at the user's own risk.
Take also care that the UDP Port 123 is not blocked otherwise the NTP synchronization doesn't work.
Why do my "old" configurations files for the Ethernet protocols no longer work? (FAQ #101681)
The configuration of the PCD by storing (on a flash file system) the files "WebSocketConfig.txt", "FTPConfig.txt" etc... does no longer work once the configuraiton has been done by the Device Configurator.
Since firmware 1.14.23 it is possible to configure the Ethernet protocols directly in the Device Configurator.
As soon as the configuration of the device is set to "Firmware 1.14.xx or newer", the configuration will be downloaded via the Device Configurator. This configuration has a higher priority than the previous configurations files. So these previous files will not work.
In case you already have configured the PCD in the old way (e.g. with the WebSocketconfig.txt) and you would like to keep it that way even after a firmware upgrade, please select "Before the version 1.14.00" and download this configuration; this will cause the Device Configurator to delete its configuration files even if the firmware used on the PCD is newer than 1.14.00.
Please note that the configuraiton files for SNTP (from the pilot tests) are no longer compatible to the ones used for FW 1.14.xx and later. When using SNTP the usage of the Device Configurator is mandatory.
Set up of a public SNTP server (FAQ #101249)
There exists about 1700 public SNTP server on the internet. A large list of these servers is available on the homepage of the NTP Pool Project (http://www.pool.ntp.org)
Example of use for a PCD in Switzerland: (need a DNS configuration)
