7.2.1 CEA-852 Device
Every L-IP acts as a device on the IP channel. It either needs to contact a configuration
server or a configuration server needs to contact the device in order to set up the proper
routing tables. Before a device can become a member of the logical IP-852 channel it needs
to have the following parameters:
IP address/netmask/gateway (either via DHCP or manual entry), see Section 6.2.4
Auto-NAT or manual NAT address if used behind a firewall/NAT router, see Section
6.2.10
MD5 secret if authentication is required, see Section 6.2.10
Please consult Sections 6.2.4 and 6.2.10 on how to setup a CEA-852 device.
7.2.2 CEA-852 Configuration Server
Any CEA-709 device that is directly connected to an IP channel (Intranet, Internet) must be
managed by a so-called configuration server (see Figure 84). 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.
The L-IP can be used together with the PC based i.LON Configuration Server utility or with
the built-in configuration server. The built-in configuration server can be enabled in the
CEA-852 server configuration menu in Section 6.2.12. 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 6.2.2
NAT address if used behind a firewall/NAT router, see Section 6.2.10
MD5 secret if authentication is required, see Section 6.2.10
Enable the configuration server, see Section 6.2.12 (server LED lights up green)
A list of IP-852 channel members, see Section 6.2.13.
Note:
If the L-IP is also used as a configuration server it needs a fixed IP address.
There are two different scenarios how a device can join an IP-852 channel. Either the
device has a valid IP address of a configuration server stored and contacts the configuration
server direct or the configuration server has a list of the IP addresses of the devices and the
configuration server contacts the device.
