Enter NTP timer server address and ports in the fields
Primary SNTP
and
Secondary
SNTP
. The L-IP will synchronize to NTP time if primary or primary and secondary NTP
servers are specified. A list of available timeservers can be found at
The
Channel timeout
is an IP-852 channel property and indicates how old a packet can be
before it is discarded. The channel timeout is set in ms. To disable the channel timeout enter
a value of 0. To select the proper value please consult Section 7.5. Setting a channel timeout
other than 0 requires a valid SNTP server entry on the configuration server.
The
Auto members
option allows members to be automatically added to the channel. If
turned on, CEA-852 devices can register on the IP-852 channel without the device being
explicitly added on the configuration server. This special feature is useful in combination
with the LPA-IP since it can add itself to the configuration server during the debug session.
Non-responding auto members are automatically removed from the channel. This feature is
turned off by default and must be explicitly turned on. Use this option with care because
new CEA-852 devices can add themselves to the channel without knowledge of the system
operator. This could cause a potential security hole.
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 device’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. 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.
Note:
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.
