The LAARS Gateway LER and RER Startup Guide LAARS Gateway Startup Guide 1 Page 5 of 32 INTRODUCTION The LAARS Gateway is an external, high performance Building Automation multi-protocol gateway that has been 1 preprogrammed for LAARS’ Mascot II, NeoTherm, and NeoTherm LC to support BACnet® MS/TP, BACnet/IP, 2 3 Metasys® N2 by JCI, Modbus TCP, and LonWorks® . Configurations for the various protocols are stored within the Gateway and are selectable via DIP switches for fast and easy installation.

Record the information about the unit. (See Section 2.2) 2. Configure each Mascot II, NeoTherm, and NeoTherm LC Modbus node address for each LAARS controller connected to the Gateway. The first node must start at 1 and go up to 8; if you have a total of 8 LAARS boilers controls connected to the Gateway. (See Appendix B.
The LAARS Gateway LER and RER Startup Guide LAARS Gateway Startup Guide Page 7 of 32 NOTE: When setting DIP Switches, please ensure that power to the board is OFF. 2.3.2 Setting the Serial Baud Rate (DIP Switch B0 – B3) for BACnet MS/TP & Metasys N2 DIP Switches B0 – B3 can be used to set the serial baud rate to match the baud rate provided by the Building Management System for BACnet MS/TP. Metasys N2 is always defaulted to 9600 baud and the B bank is disabled.

Page 16 LAARS Heating Systems Page 16 of 32 LAARS Gateway Startup Guide Appendix A. Troubleshooting Tips if the Unit is Not Working Appendix A.1. Check Wiring and Settings No COMS on Modbus RTU side. If TX/RX is not flashing rapidly then there is a COM issue on the Modbus side and you need to check the following things: o Visual observations of LEDs on Gateway. See Appendix A.3 o Check baud rate, parity, data bits, stop bits o Check Modbus device address o Verify wiring Field COM problems.
