ending in ".0 " are reserved. Some addresses ending in ".1" are used for multicast host broadcasts
and should also be avoided. Examples of valid multicast addresses include: 225.0.0.2, 225.0.0.3,
225.1.2.3. You may need to check with your network administrator to see what multicast
addresses are available for your use. Enter the desired value and click Submit Changes.
Packet Escrow: ese radio buttons enable or disable Packet escrow mode. Packet escrow is used
to escrow and reorder any out of order 852 IP CN Data packets during the escrow time.
Escrow Time: is value determines the time during which 852 IP CN Data packets are escrowed
waiting for out of order packets to show up. is only occurs when Packet Escrow is enabled.
Packet Aggregation: ese radio buttons enable or disable Packet Aggregation mode. Packet
aggregation can be used to reduce the number of 852 IP packets sent to a given device by
aggregating multiple 852 IP CN Data packets into one big 852 IP packet.
Aggregation Time: is value determines the time during which outgoing 852 IP CN Data
packets are aggregated when Packet Aggregation is enabled.
MD5 Authentication: ese radio buttons enable or disable MD5 Authentication of all 852 IP
packets sent or received by this device. MD5 authentication provides for enhanced security over
the internet. In order to work all devices engaged in communication must have authentication
enabled. An MD5 digest is appended to each sent packet. When enabled, unauthenticated packets
are dropped. Authentication only works with Echelon Devices or LonMaker when in Standard
852 Mode (see RouterSetup). When in iLONCongServer Mode, Echelon uses a non standard
authentication algorithm.
MD5 Key (hex): is value is the shared secret used by the MD5 Algorithm to compute the
authentication digest. e value must be 16 hex pairs (32 hex digits) long. is value should not
be sent in the clear over the internet. In order to accomplish this for the Ethernet version, set the
MD5 key while the GR4 router (Ethernet) is attached via an isolated Ethernet channel to the PC
running a web browser. To set the MD5 Key for WiFi version GR4 routers, rst set up the WiFi to
use WPA encryption.
Submit Changes: is button updates node parameter information and refreshes the display.
Update Member Names: is button updates the names of the devices in the channel and
refreshes the display.
Add New Device: is form adds a new device to the channel list. Enter the device name, IP
address, and port in the associated elds and the click the ADD button.
Channel List: is lists all the devices in the channel by name. e list also includes the IP address
and port of each device. e IP address eld is also a link to the status web page of the associated
device. e Info eld is a link to the device detail page for each device. e remove link will
remove the associated device from the channel list.
2.8. Device Detail Page
e device detail page provides useful information about the addressing and conguration of
each device. is page is accessed from the a device's Info link in the channel list.
