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 iLONConfigServer 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, first 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. e member names are not used by the 852 protocol and are merely
displayed as a user friendly way of distinguishing devices. e member names are usually not
shown because they are not included in the channel list update messages and must be retrieved
explicitly from the devices. Pressing this button will perform the retrieval.
Reboot
: is button reboots the device. See the Router Setup page for a detailed description of the
reboot button behavior.
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 field is also a link to the status web page of the associated
device. e Info field is a link to the device detail page for each device.

10.2. Manual Mode Channel List Page
e Manual mode page operation is the same as Normal mode with the exceptions that multi-cast
addressing may be specified and devices may be added and removed from the channel. Only
those fields that are different from Normal mode are described here. In Manual mode, the page
looks like the following.
