NOTE: Never set a BACnet MS/TP MAC Address from 128 to 255. Addresses from 128 to 255 are Slave
Addresses and can not be discovered by BMS Front Ends that support auto discovery of BACnet MS/TP
devices.
Set DIP switches A0 – A7 to assign MAC Address for BACnet MS/TP for the MCS-BMS-GATEWAY FPC-ED4.
Please refer to Appendix A.1 for the complete range of MAC Addresses and DIP switch settings.
NOTE: When using Metasys N2 and Modbus TCP/IP, the ‘A’ Bank of DIP
switches are disabled and not used. They should be set to OFF.
NOTE: When setting DIP Switches, please ensure that power to the boaris OFF.

BACnet MS/TP and BACnet/IP: Setting the Device Instance
•
The ‘A’ Bank of DIP switches are used for two purposes:
• For BACnet MS/TP, they are used to set the BACnet MS/TP MAC address (Section 3.3.2)
• For both BACnet MS/TP and BACnet/IP, they are also used to determine the BACnet Device In-
stance values
• The BACnet Device Instance can range from 1 to 4,194,303.
•
The BACnet device instances will be calculated by taking the Node Offset (default is 18100)
found in Web Configurator and adding it to the value of the ‘A’ Bank DIP switches.
When more than one device is connected to the MCS-BMS-GATEWAY, the subsequent BACnet Device In-
stance values will be sequential from the first/previous device.
For example:
•
Given that Device Instance = Node_ A Bank DIP switch value = Default Node_Offset
value = 18150 = ‘A’ Bank DIP switch value = 03 (as per Appendix A.10 DIP Switch Setting)
• Then the Device Instance values for the devices are: = Device 1 Instance = 18153 = Device 2
Instance = 18154
4.3.4
Metasys N2: Setting the Node-ID
• Set DIP switches A0 – A7 to assign a Node-ID for Metasys N2 to the MCS-BMS-GATEWAY.
•
Node-ID’s range from 1-255.
• Refer to Appendix A.10 for the full range of addresses for setting Node ID.
4.3.5
BACnet MS/TP: Setting the Serial Baud Rate for BMS Network
DIP Switches B0 – B3 can be used to set the serial baud rate to match the baud rate required by the Building
Management System for BACnet MS/TP.
• The baud rate on MCS-BMS-GATEWAY for Metasys N2 is set for 9600. DIP Switches B0 – B3
are disabled for Metasys N2.
NOTE: When setting DIP Switches, please ensure that power to the board is OFF.
