L-INX User Manual 63 LOYTEC
Version 4.0 LOYTEC electronics GmbH
The Roaming members option allows tracking CEA-852 devices when their IP address
changes. This feature must be turned on if DHCP is used and the DHCP server can assign
different IP addresses to the same device (same Neuron-ID). In combination with Auto-
NAT the LINX‘s router can also be operated behind NAT routers, which change their IP
address between connection setups. For more information on this topic refer to Section
7.3.1. The roaming member feature is turned on by default. It is recommended to turn off
this feature if DHCP is not used or if the DHCP server always assigns the same IP address
to a given MAC address.
Use the drop-down box MD5 authentication to enable and disable MD5 authentication. If
MD5 authentication is enabled, all devices on the IP-852 channel must have MD5 enabled
and must use the same MD5 secret. Note that MD5 authentication cannot be used together
with the Echelon‘s i.LON 1000 since the i.LON 1000 is not fully compliant with the
CEA-852 authentication method. MD5 can be used with the i.LON 600. The MD5 secret
can be entered over the Web interface. You may enter the 16 bytes as one string or with
spaces between each byte,
e.g., 00 11 22 33 44 55 66 77 88 99 AA BB CC DD EE FF.
It is recommended, however, to enter the secret locally and not over an Internet connection.
It is best to use a cross-over Ethernet cable connected to the PC.
4.2.10 CEA-852 Channel List
This page is only available on CEA-709 L-INX models with the router option (101, 111,
121, 151). If the configuration server is enabled on the LINX, the CEA-852 device list can
be seen in the CEA-852 channel list menu. An example is given in Figure 45.
The Add Device button is used to add another CEA-852 device to the IP-852 channel. The
Reload button updates the Web page and the Recontact button contacts all devices to
update their status. The Execute button executes the option selected in the adjacent drop-
down box on the checked members. Each member can be selected for that action in an
individual check-box in the Sel column. Actions available are: disable, enable, delete,
assign to NAT, and remove from NAT. For more information on the actions on NAT
routers refer to Section 7.3.2.
