A) To identify a device using its service pin message

To identify a device using a service pin message, in the station with the LonNetwork:
Step 1 Right-click the LonNetwork and select Views > Lon Utilities Manager.
The Lon Utilities Manager appears.

Step 2 At the bottom, click the lower-left drop-down control (command menu) and select Identify.

Click the drop-down control to the right (command submenu) and select Service Pin.
Note: For this command, selected LON device makes no difference (“LocalLonDevice”, other).

Step 3 Click the Execute button.
The view updates to show a timestamp with “Waiting on service pin” below.

Step 4 At any connected LON device, press its service pin.
In the utilities manager view, the device’s domain table is shown, including the domain length (Domain
Len) and ID for the device. If the device is configured on something other than the zero-length domain
(Domain Len not “0”), you must configure the LonNetwork’s working domain to match. See the next
 section, “To change the working domain”.

B) To change the working domain

Note: Niagara’s working domain always uses domain index 0 (do not confuse with zero-length domain). If you
change the default working domain, the zero-length domain is retained, but moved to domain index 1. If
operating as network manager (typical), the network’s Lon Netmgmt always needs access to the zero-length
domain in order to receive service pin messages.
To change the working domain for a station’s LonNetwork, from the zero-length domain:

Step 1 Right-click the LonNetwork and select Views > Property Sheet. The property sheet appears.

Step 2 In the property sheet, click to expand Lon Netmgmt .

Step 3 In Domain Id property, click the length drop-down and select the matching domain-length used by
other Lonworks devices (either 1, 3, or 6).

The adjacent id field changes from empty to showing bytes (for example, 00 or 00 00 00).

Step 4 In the id field, enter the domain id used by other devices. Domain IDs are hexidecimal bytes. For
example, if domain length is 1, the ID range is from 00 to FF.

Step 5 Click the Save button.

The LocalLonDevice is now configured with a non-default working domain.
Note: To place other (existing) Lon devices in this domain, you must recommission them.
