Foreign Device Settings
Some BACnet/IP devices also support a feature called Foreign Device Registration (FDR). FDR allows a BACnet/IP device
to send broadcast messages to a device with BBMD enabled. The BBMD-enabled device will then forward these broad-
cast messages to all other BBMDs and onto all other FDR devices. If a subnet has only FDR supported devices, then it
does not need a local BBMD. These devices can register directly with a BBMD on another subnetwork.

Network MS/TP Ports

BACnet MS/TP and Modbus RTU communications are made by connecting directly to separate RS-485 ports. On-board
RS-485 Port is the controller's onboard RS-485 port. The following network configuration parameters are for an RS-485
port that is used to communicate with BACnet MS/TP controllers.

IP address of a controller (foreign device) located on another subnetwork

Description
Enables/disables the controller's BACnet MS/TP connection. If the controller has been configured to use Modbus RTU,
this option cannot be enabled.
Network number identifies a LAN for routing purposes. All controllers with the same network number are members of the
same logical BACnet network. See
Recommended baud rate setting is 38 400. See
The ECLYPSE controller's MAC Address on the BACnet MS/TP Data Bus.
When commissioning a BACnet MS/TP Data Bus, it is useful to start with the Max Master set to 127 so as to be able to
discover all devices connected to the data bus. Then, once all devices have been discovered and the MAC Addressing is
finalized by eliminating any gaps in the address range, set the Max Master (the highest MAC Address) to the highest
Master device's MAC Address number to optimize the efficiency of the data bus. See
Frames.
For the ECLYPSE controller, this should be set to 20. See
