Synchronising the PC Clock
With the network service SNTP (simple network time protocol) it is possible to synchronise the internal clock of a PC with the time of the OpenCom 100.
Requirements
You must enter the time zone so that the OpenCom 100 can calculate the time of the internal clock back to the GMT (Greenwich Mean Time) required for SNTP:
1. Go to the Configurator, SYS Configuration: System menu. Click on Change.
2. Under Internet time (SNTP), enter the Time zone for which the time of the
OpenCom 100 applies and whether summer time is allowed for. Confirm this with Assign.
Configuring SNTP
For various operating systems, you can use one of the numerous SNTP programmes offered for downloading on the Internet. Configure the OpenCom 100 as an SNTP server for such programmes.
SNTP with Windows 2000
Here you configure the SNTP server as follows:
1. Log on as the administrator. Start the Command Prompt under Start: Pro-
grams: Accessories.
2. Enter the command line “net time /setsntp:192.168.99.254”. Confirm with the enter key. This command changes the setting for the SNTP server address in the system registry. Close the command line.
