IP-852 Channel User’s Guide 15
You can change the port number; however, you must avoid any
conflicts with other applications that are using the IP network
card. Each IP-852 interface definition you create with the
L
ONWORKS Interfaces application must use a unique port. If
you modify the port used by an IP-852 interface definition, the
change will be implemented once all applications using the
IP-852 interface definition are closed.
Channel Timing
Select the channel delay. You have the following two choices:
• LAN. Select this if your IP-852 channel spans a local area
network. This is the default.
• WAN. Select this if your IP-852 channel spans a wide area
network. This results in a larger channel delay value.
Authentication
If the IP channel used by this IP-852 interface definition is
using authentication, enter the authentication key as a
32-character hexadecimal string representing a 128-bit MD5
key. The following is an example authentication key:
A9048749F4BF89590310C547BD4594D7
You can enable authentication for an IP-852 channel with the
IP-852 Configuration Server. See
MD5 Authentication in
Chapter 3 for more information on using authentication on the
IP-852 channel.
Configuring an IP-852 Device as a LONWORKS Router
An IP-852 device may be either a native IP-852 device or a router to a native LONWORKS
channel. An LNS server may be configured as a native IP-852 device, and any IP-852 to
native L
ONWORKS compliant router may be configured as a LONWORKS router.
Examples of native L
ONWORKS channels are TP/FT-10 free topology twisted pair and
TP/XF-1250 high-speed twisted pair. IP-852 to L
ONWORKS routers are available from
multiple manufacturers. Echelon’s IP-852 to L
ONWORKS routers include versions of the
SmarServer Energy Manager and i.LON 100 Internet Server with IP-852 routing
enabled, and the i.LON 600 L
ONWORKS/IP-852 router.
The procedure that you will use to configure an IP-852 device as a L
ONWORKS router
depends on the network management tool that you use to configure you L
ONWORKS
network. You can use any network management tool that complies with the ISO/IEC
14908-1 Control Network Protocol. The following procedure illustrates how to use the
LonMaker tool to integrate an IP-852 router with the L
ONWORKS network described in
Figure 2.8. For more information on the LonMaker tool, see the LonMaker User's Guide.
1. With the IP-852 Configuration Server running, create a new LonMaker network and
specify the IP-852 network interface created with the L
ONWORKS Interfaces
application in the previous section as the network interface. Change the name of
Channel 1 to IP852 Channel and assign specify IP-10L (if using a local IP network)
or IP-10W (if using a wide area IP network, such as the Internet) as the transceiver
type in the Channel's properties.
