Aggregation Time
: This value determines the time during which outgoing 852 IP CN Data
packets are aggregated when Packet Aggregation is enabled.
MD5 Authentication
: These 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 Router Setup). When in iLON Config Server Mode,
Echelon uses a non standard authentication algorithm.
MD5 Key (hex)
: This value is the shared secret used by the MD5 Algorithm to compute the
authentication digest. The value must be 16 hex pairs (32 hex digits) long. This 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
: This button updates node parameter information and refreshes the display.
Update Member Names
: This button updates the names of the devices in the channel and
refreshes the display. The member names are not used by the 852 protocol and are merely
displayed as a user friendly way of distinguishing devices. The 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
: This button reboots the device. See the Router Setup page for a detailed description of
the reboot button behaviour.
Channel List
: This lists all the devices in the channel by name. The list also includes the IP
address and port of each device. The IP address field is also a link to the status web page of the
associated device. The Info field is a link to the device detail page for each device.
2.10.2. Manual Mode Channel List Page
The 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.
