Ceag CG-S / IP-Router + 1P Betriebsanleitung Seite 47

If the CG-S / IP Router+ 1P is used simultaneously as configuration server, certain device settings (e.g. NTP
server, unicast and multicast addresses) are not available as they are overwritten by the corresponding
server settings.
Device Name
Enter a unique name for the device under Device Name. The basic node-ID is used here as default. This is used by
the router to register itself with the configuration server and to identify itself compared to other participants in the
LON/IP channel.
The Device Name must be unique in the LON/IP network.
IP Unicast Port
If you wish to assign a port deviating from the standard (port 1628) for the exchange of LON packets on the CEA-
852 interface, enter this under the IP Unicast Port option.
If unicast or multicast addresses have been assigned on the configuration server, the local settings of a
device are overwritten.
IP Multicast address and port
LON packets can be sent in parallel on the LON/IP channel to several recipients via the IP multicast addressing.
This contributes significantly to reduction of network load. Enter the values specified by the administrator under IP
Multicast Address and IP Multicast Port.
All participants in a LON/IP channel should use the same multicast address and the same port number.
IP TTL
The specified Time To Live gives the number of router hops over which a CEA-852 packet can be maximally for-
10
warded. This can limit the communication of messages, which also leads to a reduction of bus load. The maximum
value is 255 (default = 16).
Configuration Server
A LON/IP channel is usually managed via the configuration server, and is integrated in the CG-S / IP Router+. It can
be activated via SETTINGS > CATEGORIES > CEA-852 Server.
Enter the address of the CG-S / IP Router+ on which the configuration server runs, and the port (1629 acc. to CEA-
852 standard). No entry can be made here if the configuration server is run on the same device.
You can check whether assignment of the configuration server was successful with the following:
1. The status/reset LED lights up green,
2. In the web interface of the router, you can see whether data and configuration packets have been transmitted
via STATISTICS > CEA-852 > Packets.
3. Members on the Channel displays the number of the other participants. The Get Channel List link calls up an
overview.
4. Other devices can be reached in the LON/IP network.
