The tool auto recognizes if there are existing configurations and applies them in the tool based on what is selected.

If the user needs to make changes to the current configurations already set up:

They can either re-run the auto-configuration again which will override the existing configurations

They can manually configure each device in the manual window.

 

 

The following fields on the tool are below:

Broadcast Address - address of what is being searched for

Custom Broadcast Address - if the address of what is being searched doesn't appear in the Broadcast Address dropdown, the user can type it in here. User can also specify the port if needed if other than the standard port of 47808.

Local Address - address of local machine doing the discovering (not configurable in this window, refer to the BACnet Global Config tool below)

Instance Number Start - the lowest instance to check can be configured here to narrow search results (default is 0).

Instance Number End - the highest instance to check can be configured here to narrow search results (default is 4194303).

Network Number - to narrow network, the user can specify it here else leave as is (default is 65535).

Timeout (seconds) - time spent to try and discover for said devices (default is 8).

To send a global broadcast as an unconstrained “Who Is”, set both the Instance Number Start and End to -1. This will send a broadcast without the low/high instance limits. When the BBMD receives these global broadcast requests, it will then forward it to it’s peer BBMDs.
