It will take 3 minutes to discover all Modbus RTU devices attached to the ProtoNode. - Once the ProtoNode has discovered all of the Modbus RTU devices, set the S3 DIP switch to the OFF position to save the recently built configuration. ProtoNode RER and LER S3 DIP Switch Auto-Discovery Mode Auto-Discovery ON Build New Configuration Auto-Discover OFF Load Current Configuration S3 On Off NOTE Initial Auto Discovery Cycle All boilers MUST be powered and connected to the ProtoNode before cycling power to the ProtoNode. The ProtoNode will auto discover only connected boilers. If a boiler is connected after the ProtoNode has completed auto discovery it will not find the new boiler. Page 4 of 40 Part Number

5 2.4 BACnet MS/TP Setup (skip if this protocol is not used by the EMS) Set MAC Address - Set ProtoNode MAC Address - Set DIP Switch (A0 A7) for a MAC address between 1 and 127 which are Master addresses. Addresses between 128 and 255 are Slave addresses. BACnet Master Addresses pass tokens on the BACnet MS/TP network and can be Auto-Discovered by Energy Management System (EMS) front end systems that support Auto-Discovery. BACnet Slave Addresses cannot pass Tokens and will never be Auto-Discovered by EMS front end systems that support Auto- Discovery. Figure 2: A0 A7 DIP Switches (MAC address 3 is show) - Please refer to Appendix E for the full range of addresses to set Node-ID/Device Instance. - NOTE: When setting DIP Switches, please ensure that power to the board is OFF Set Serial Baud Rate DIP Switches B0 B3 are used to set the serial baud rate to match the baud rate provided by the Energy Management System.
