utility or with any LOYTEC configuration server. If multiple CEA-852 devices behind one
NAT router are added, the Auto-NAT setting in the CEA-852 devices is recommended to be
used with the LINX-101 configuration server or an L-IP configuration server. Please refer
to the following sections on how to setup the device and the configuration server.
If the ―Auto member‖ feature is enabled in the configuration server, the CEA-852 device
can add itself to the IP-852 channel without explicitly adding the device at the configuration
server. Note, that enabling auto member is a potential security hole since any device can
add itself to the IP-852 channel.
7.2.1 Configuration Server for Managing the IP-852 Channel
7.2.2 Overview
Every logical IP-852 channel requires one configuration server that manages all CEA-852
devices (LINX-121, L-IP, LOYTEC NIC852,

this channel. A simple example is shown in Figure 150. A configuration server keeps a list
of all devices on a logical IP-852 channel and distributes the routing information between
those devices. If a device wants to join an IP-852 channel, it needs to register itself at the
configuration server. Traditionally, a dedicated Windows PC is used to act as the
configuration server. The L-INX contains an embedded configuration server and can
therefore replace the PC.
The configuration server can be enabled in the L-INX in the CEA-852 server configuration
menu in Section 4.2.9. This configuration server can manage one IP-852 channel and up to
256 devices on this IP-852 channel. In order to setup the configuration server, one must
specify the following parameters:
IP address/netmask/gateway (either via DHCP or manual entry), see Section 4.2.4
NAT address if used behind a firewall/NAT router, see Section 4.2.7
MD5 secret if authentication is required, see Section 4.2.7
Enable the configuration server, see Section 4.2.9 (server LED lights up green)
A list of IP-852 channel members, see Section 4.2.10.
Note:
If the LINX-101 is used as a configuration server it needs a fixed IP address.
