The CEA-852 protocol settings are displayed in the settings box on the right-hand side as
shown in Figure 50. Typically, the device is added to an IP channel by entering the relevant
information on a configuration server. The configuration server then contacts the CEA-852
device of the L-DALI and sends its configuration.
The field
Config server address
and
Config server port
display the IP address and port of
the configuration server, which manages the L-DALI and the IP channel. The field
Config
client port
represents the IP port of the L-DALI’s CEA-852 device. This setting should be
left at its default (1628) unless there are more than one CEA-852 devices operating behind a
single NAT router. Please refer to the L-IP User Manual [1] to learn more about NAT
configuration.
In the field
Device name
the user can enter a descriptive name for the L-DALI, which will
appear in the IP channel to identify this device. You can enter a device name with up to 15
characters. It is recommended to use unique device names throughout the IP channel.
The
Channel mode
field reflects the current channel mode of the CEA-852 device. It is
configured by the configuration server. If there are any two devices in the channel which
use the same IP address but different ports (e.g., multiple L-DALI behind one NAT router)
the channel switches to
Extended NAT mode
. Please refer to the L-IP User Manual [1] to
learn more about configuring the Extended NAT mode in the configuration server.
The configuration server sets the
SNTP server
addresses and the
Channel timeout
.
The filed
Escrow timeout
defines how long the CEA-852 device on the L-DALI waits for
out-of-sequence CEA-852 data packets before they are discarded. Please enter the time in
ms or ‘0’ to disable escrowing. The maximum time is 255 ms.
The field
Aggregation timeout
defines the time interval in which multiple CEA-709
packets are combined into a single CEA-852 data packet. Please enter the time in ms or ‘0’
to disable aggregation. The maximum time is 255 ms. Note that disabling aggregation will
negatively affect the performance of the CEA-852 device of the L-DALI.
The field
MD5 authentication
enables or disables MD5 authentication. 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. In the following field
MD5 secret
enter the 16-byte MD5 secret.
Note that for security purposes the active MD5 secret is not displayed. 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.
Also note that entering the MD5 secret on the Web interface may pose a security risk. Since
the information is transmitted over the network it can be subject for eavesdroppers on the
line. It is recommended to use a cross-over cable.
In the field
Location string
the user can enter a descriptive test which identifies the
physical location of the L-DALI. A location string can have a maximum length of 255
characters. This is optional and for informational purposes only.
If the CEA-852 device on the L-DALI is used behind a NAT router, the public IP address of
the NAT router or firewall must be known. To automatically detect the NAT address leave
the
Auto-NAT
checkmark enabled.
The
Multicast Address
field allows the user to add the CEA-852 device of the L-DALI
into a multi-cast group for the CEA-852 IP channel. Enter the channel’s IP multi-cast
address here. Please contact your system administrator on how to obtain a valid multi-cast
address. To learn when it is beneficial to use multi-cast addresses in your channel please
refer to the L-IP User Manual [1].
