Click Synchronize to open the SmartServer Resync dialog and manually
resynchronize the SmartServer with the selected OpenLNS network
database. See the Manually Synchronizing the SmartServer to an
OpenLNS Network Database section later in this chapter for more
information.
This property is only available for networks in the SmartServer tree.
Use LNS Network
Interface To use an OpenLNS or LNS network interface, select this option and then
select the network interface to be used for communication between the
OpenLNS or LNS Server and the network.
If you are designing a network, you can clear this option to specify that the
SmartServer is not attached to the network. This is the default.
Network
Management
Mode Select when network configuration changes are propagated to devices.
You have three choices:

OnNet. Changes are sent immediately to the devices on the network.
Select OnNet if you are installing an engineered network, or if you
are designing and installing an ad-hoc network at the same time.

OffNet. Changes are stored in the network database and then sent to
the devices on the network when you place the SmartServer OnNet.
Select OffNet if you are designing an engineered network.

Maintenance. Same as OnNet except that the SmartServer does not
send out heartbeat and polling messages. This increases the available
bandwidth by freeing up the consumption from checking data point
heartbeats, sending poll requests, and receiving poll message
responses. Select Maintenance to speed up the network
commissioning process. This is mode is typically required for power
line repeating networks.
Domain Length You can change the length (in bytes) of the domain ID. The domain is the
top level of the LonTalk domain/subnet/icon addressing hierarchy. The
domain length may be 0, 1, 3, or 6 bytes. The zero-length domain,
though, is reserved for the use of the OpenLNS architecture and cannot be
used as the system’s domain.
This property is not available for the network in the SmartServer tree
when the SmartServer is operating in LNS mode (LNS Auto or LNS
Manual).
Domain ID You can change the domain ID in hexadecimal notation. If you enter an
ID that has fewer bytes than that specified in the Domain Length box, the
domain ID will be padded with leading zeroes.
This property is not available for the network in the SmartServer tree
when the SmartServer is operating in LNS mode (LNS Auto or LNS
Manual).
Use
Authentication Enables the SmartServer to send authenticated network management
commands such as commissioning to the devices on the network. To
enable authentication, select the Use Authentication check box, and
specify a 6-byte or 12-byte key (12-digit or 24-digit hexadecimal string).
To use a random authentication key, click Generate Random Key.
When the SmartServer commissions a device, it will set the device’s key
