Adapting The Time Settings - Ceag CG-S / IP-Router + 1P Betriebsanleitung

The use of a software MAC Address that replaces the hardware MAC Address of the device (if specified)
must be carefully considered. With devices with identical MAC addresses, serious network errors
may occur.

3.5 Adapting the time settings

The CEA-852 standard recommends synchronisation of the routers to permit the detection of obsolete messages
for a LON/IP network. For this purpose, synchronisation is recommended with the NTP protocol.
Both an NTP client and an NTP server are installed in the CG-S / IP Router+ 1P, meaning that the device can re-
ference the current time information from one or several NTP servers in the local network or the internet, but can
also function as such a server in the local network. Simultaneous operation is possible, meaning the router can for
example call up the precise time from a specific NTP server on the internet and is at the same time available locally
for connected clients. If the NTP Client option is inactive, the router uses the integral time clock as a reference.
Open the SETTINGS tab, and under CATEGORIES on the left select Time to carry out the settings.

You should make sure that all devices connected with the CG-S / IP-Router+ 1P and the router itself are time-syn-
chronised.
The integral time clock has a buffering of approx. 36 hours. If the router is longer without power, you must reset the
time manually or via NTP.
The specific function is activated/deactivated by clicking on the NTP Server or NTP Client checkbox. One or several
time servers can be entered into the NTP Servers field. Use a separate line for each server address.
Make sure that with use of external time servers, specifications for the gateway and DNS servers are
entered in the IP settings (see above).
You can also manually enter the desired time or date (in UTC/GMT) under Local Date or Local Time. In this case the
NTP Client function must not be selected as otherwise the time is overwritten again by the NTP synchronisation.
If the configuration server is activated as NTP server, the settings here are overwritten.
