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. It is not necessary to download any
configuration files to support the required applications.
This document provides the necessary information to facilitate installation of the Gateway.
1.1
BTL Mark – BACnet Testing Laboratory
The BTL Mark on the Gateway RER is a symbol that indicates that a product has
passed a series of rigorous tests conducted by an independent laboratory which
verifies that the product correctly implements the BACnet features claimed in the
listing. The mark is a symbol of a high-quality BACnet product. Go to
http://www.bacnetinternational.net/btl/ for more information about the BACnet
Testing Laboratory.
1.2
LonMark Certification
LonMark International is the recognized authority for certification, education, and
promotion of interoperability standards for the benefit of manufacturers, integrators
and end users. LonMark International has developed extensive product certification
standards and tests to provide the integrator and user with confidence that products
from multiple manufacturers utilizing LonMark devices work together

BACNET/LONWORKS SETUP THROUGH PROTOCESSOR GATEWAY RER/LER
2.1
Installation steps for the customer
1.
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.1 Note that NeoTherm LC units each have
two controllers.)
3.
Set device addressing: MAC Address and Device Instance/Node-ID for BACnet MS/TP, BACnet/IP, Metasys
N2, and Modbus TCP. (See section 2.3)
4.
Connect the Gateway to the Field protocol port and Honeywell’s Display (RS-485 gateway port) to the
Gateway’s RS-485 interface. (See Section 3)
5.
Power up the Gateway RER and LER.
6.
If the Controls Contractor requires LonWorks Fserver.xif file for the Gateway LER, see Appendix A.3 to
generate the file.
7.
If the Field protocol is BACnet/IP or Modbus TCP, refer to Section 4 to run the Gateway web GUI to
change IP address or the RUINET utility program to change the IP address (Section 4).
2.2
Record Identification Data
Each Gateway has a unique part number located on the underside of the unit. The numbers are as follows:


FieldServer # FPC-N34-103-122-0701 Modbus RTU to BACnet MSTP, BACnet IP, N2, Modbus TCP,
RER, Metasys N2 by JCI.
FieldServer # FPC-N35-103-401-0702 Modbus RTU to LonWorks, LER.
This number should be recorded, as it may be required for technical support.
2.3
Configure the DIP Switches
2.3.1 Setting the Node/ID Device Instance (DIP Switch A0 – A7) for BACnet MS/TP,
BACnet/IP, & Metasys N2

The A Bank DIP switches on the Gateway RER allow users to set the Node-ID/Device Instance on the Field
RS-485.

DIP switches A0 – A7 can also be used to set the MAC Address for BACnet MS/TP and BACnet/IP.
Figure 1: A0 – A7 DIP Switches

Please refer to Appendix C.2 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.
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.

2.3.3 Using S0 – S3 bank of DIP Switches to select and load Configuration Files

The S bank of DIP switches, S0 - S3 is used to select and load a configuration file from a group of
pretested/preloaded configuration files which are stored in the Gateway RER (BACnet MS/TP, BACnet/IP
and Metasys N2) and LER (LonWorks).

Connect the Gateway to the field network with the LonWorks terminal using a twisted pair non-shielded
cable. LonWorks has no polarity.
Power-Up the Gateway RER or LER
Apply power to the device. Ensure that the power supply used complies with the specifications provided in
Appendix C.1. Ensure that the cable is grounded using the “Frame-GND” terminal. The Gateway is factory set for
9-30VDC or 12-24 VAC.

Commissioning the Gateway-LER on a LonWorks network
Commissioning may only be performed by the LonWorks administrator.
To commission the Gateway LER LonWorks port, insert a small screwdriver in the commissioning hole on the face
of the LER’s enclosure to access the Service Pin. See the illustration on the Gateway LER as to which way to toggle
the screw driver during commissioning.

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.
o Visual observations of LEDs on Gateway. See Appendix A.3
o Visual dipswitch settings (using correct baud rate and device instance)
o Verify IP address setting
o Verify wiring
If the problem still exists, a log needs to be taken and sent to FieldServer.
Appendix A.2. Take Log With Our FieldServer Utilities

Once the log is complete, email it to support@protocessor.com. The log will allow us to rapidly diagnose
the problem.

Make sure the FieldServer utilities are loaded on the PC.
http://fieldserver.com/techsupport/utility/utility.php

Disable any wireless Ethernet adapters on the PC/Laptop

Disable firewall and virus protection software


Description
Unused
The RUN LED will start flashing 20 seconds after power up, indicating normal operation.
The SYS ERR LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady red
light will indicate there is a system error on the Gateway LER. If this occurs, immediately report the
related “system error” shown in the error screen of the RUI interface to FieldServer Technologies for
evaluation.

Appendix C.1.1.
Compliance with UL Regulations
For UL compliance, the following instructions must be met when operating the Gateway.

The units shall be powered by listed LPS or Class 2 power supply suited to the expected operating
temperature range.

The interconnecting power connector and power cable shall:
 Comply with local electrical code
 Be suited to the expected operating temperature range
 Meet the current and voltage rating for the Gateway/Net

Furthermore, the interconnecting power cable shall:
 Be of length not exceeding 3.05m (118.3”)
 Be constructed of materials rated VW-1 or FT-1 or better

If the unit is to be installed in an operating environment with a temperature above 65 °C, it should be
installed in a Restricted Access Area requiring a key or a special tool to gain access.

This device must not be connected to a LAN segment with outdoor wiring.
