CAUTIONS
○
Multiple BBMD's on an IP subnet disrupt BACnet communications. Define only one BBMD per
subnet.
○
Unless explicitly modified, the UDP Port for BACnet/IP is 0xBAC0 (47808). Do not change this
parameter unless you made a change in the router.
4
In a text editor such as Notepad, create a list of the routers that will be BBMD's. List each IP address on
a separate line. (Maximum of 50 IP addresses per file)
5
Save the file to your folder of choice with a .bdt extension instead of .txt.
NOTE
".bdt" is a
Broadcast Distribution Table
file.
6
Open the
BBMD Configuration Tool
.
7
In the
IP Address
or
Host Name
field, type the IP address of the router that functions as the BBMD
(BACnet Broadcast Management Device) for its subnet.
8
To check if the router has an existing BBMD table, click
Broadcast Distribution Table Read
button.
9
If the
Broadcast Distribution Table
contains IP addresses that are not in your .bdt file, verify that they are
valid BBMD's and, if so, add them to your .bdt file.
NOTES
○
The BDT's in each BBMD must be identical. Be sure to repeat this entire process whenever a BBMD
is added.
○
If needed, disable the checkbox next to
Show Broadcast
to limit the amount of scrolling text that is
displayed.
10
Click the
Broadcast Distribution Table
Browse
button and select the .bdt file that you made in step 4.
11
Verify that the appropriate IP address is still in the
IP Address
or
Host Name
field.
12
Click the
Broadcast Distribution Table
Write
button.
13
Click
Read
again to verify that the new .bdt file was written to the router. See example below.
