About PUP Device Discovery Config

When you click Discover in the Pup Device Manager, a discovery config dialog appears, as shown in Figure 6.

Figure 6. PUP device discovery config dialog

Fields in this dialog are explained as follows:

Start Address

Beginning address range (typically unit number) for PUP device discovery. Default value is 0.
Stop Address

Ending address range (typically unit number) for PUP device discovery. Default value is 65534.

To learn what devices are on the wire, it is best if you narrow the Start Address and Stop Address range, because the learn process has to loop through and attempt to talk to each and every address in the range. Attempting to talk to 65535 would take quite a long time!
Search By

Allows selection of either:
- “search using unit number” — (default) Niagara will search using the specified start and stop address range of unit numbers.
- “search using serial number” — Niagara will search using the specified start and stop address range as serial numbers (a “back door” search of devices that use the American Auto-Matrix method of serial number to access devices).
Controller List

Specifies the XML-formatted file to be referenced when doing online “Discovers” of PUP devices, as also specified by the “Device Types File” property of the PupNetwork. The file describes device types, channel names, channel search ranges, and so forth. For more details, see Modifying DeviceTypes.xml.
