Communication across IP subnets requires a Broadcast Management Device (BBMD)
device or support for Foreign Device Registration (FDR) feature. The BASstat supports the
FDR feature to register with a remote BBMD which could be a BACnet client or a BMS
headend. To communicate with BACnet clients across subnets, the BAST321HP-BW2 can
do FDR registration with a remote BBMD. The BACnet BBMD feature requires a BACnet
device with BBMD capability, such as a BACnet router or other, to be installed and
configured on the network. BBMD allows discovery of all BACnet/IP devices in the IP
subnet instead of just the FDR device.
•
Select As Foreign Device.
•
The BBMD IP is the address of the BBMD device on the remote network. Enter the
address of the BBMD with which the BAST-321HP-BW2 will perform Foreign Device
Registration (FDR) if there is no local BBMD device in the same subnet as the BAST-
321HP-BW2 providing communication to the remote subnet.
•
Enter the UDP port for BBMD.
•
Time to Live is the BBMD registration time. Specify the seconds between successive
FDR registrations. Recommended value is 100.
