LonWorks Driver
This screen is used to configure a USB@LON interface to access a LonWorks network.
Settings Tab
Label
Label is the name of the item as displayed in the Device Tree.
All items in the Device Tree are sorted alphabetically by label. Folders may be used to organize items.
Description
Description is optional text that describes the item. It can be any descriptive text or be left blank.
Interface Serial #
This is the eight digit serial number found on the back of the USB@LON interface. Enter it here as a single run of eight numbers and letters (85WZ03E4).
Be careful with letters and numbers that look similar, such as O/0, I/L/1, etc. If it seems to not be communicating and the USB@LON power light is not lit, check the serial number again.
Network Delay
The network delay can be used to throttle traffic on the USB@LON interface.
The value specified here is the number of milliseconds to wait between network transmissions by the USB@LON. It may be set higher on busy networks or for slower devices causing read errors. It may be set lower for faster point updates. Except in extreme conditions, it should be set to 100 or lower.
Domain
This is the domain ID the USB@LON interface should be set to. It can usually be left blank but if a router is in use on this network, it should be set to match the domain of the router.
The domain ID must be 0,1,3 or 6 pairs of hexadecimal digits (0-9, A-F). For example: B0, F21804 or E43C10563D92.
If the domain ID is set (non-blank) with no routers in use, the USB@LON interface will be limited to accessing only devices on that domain. This is useful in some specialized cases, but is not normally desired.
Subnet/Node
This is the subnet and node the USB@LON interface should be set to. They can be set to any subnet/node that does not already exist on the network.
The subnet and node must be set even if routers are not in use.
Group Settings Tab
The group settings are used to determine which user groups can see this item in the tree. The default setting is "Everyone". Unchecking "Allow Everyone" enables selecting individual groups.
If a user group is not allowed to see an item, that group will also not be able to see any items under it in the tree.
There are "Check All" and "Uncheck All" buttons in the upper-right corner to make major changes easier.
Group access permissions are for the tree only. If an item is placed on a graphic that a group can view, that group would still be able to access it.
Advanced Tab
Name
Name is used for advanced features. If left blank, it will be assigned automatically. It is recommended that the default value not be changed.It can be up to 48 characters. Only A-Z, a-z, 0-9, period (.) and underscore (_) are allowed. Names are case sensitive.
