1. INTRODUCTION
GF-129
ProtoNode is an external, high performance, Building Automation multi-protocol gateway that has been
preprogrammed for AERCO’s equipment to support BACnet®
TCP, and LonWorks®
the ProtoNode and are selectable via DIP switches for fast and easy installation. There is no need to download any
configuration files to support the required applications.
This provides the necessary information to assist the Installers of the boilers/heaters with the installation of the
ProtoNode RER on BACnet MS/TP, BACnet/IP, and Metasys N2 by JCI networks and installation of the ProtoNode
LER on a LonWorks network.
BACnet International BTL certification is the highest level of BACnet conformance tests that a product can be
subjected to.
• The ProtoNode RER is BACnet BTL Certified.
• The ProtoNode LER is LonMark Certified.
The ProtoNode units feature a very small form factor, as indicated in the dimensional illustration below:

2. BACNET/LONWORKS SETUP THROUGH PROTOCESSOR PROTONODE RER/LER
2.1 Installation Steps For The Customer
1. Set the A, B, and S DIP Switch banks for field protocol baud rate, Node-ID/Device Instance, and proper
configuration. See Section 2.3.
2. Connect the ProtoNode to the Field protocol port and AERCO’s Control System/Boiler Management
System – RS-232 or RS-485 interface. See Section 3.
3. Power up the ProtoNode RER or LER. After power up, the device is installed on BACnet MS/TP, Metasys
N2, or LonWorks for the LER.
4. Where the Field protocol is BACnet/IP, refer to Section 5 to run the Ruinet utility program to change the
IP address. No changes to the configuration file are necessary.
2.2 Record Identification Data
Each ProtoNode has a unique serial number located on the underside of the unit. The number format is FPC-N3XXXX-XXX-XXXX. This number should be recorded as it may be required for technical support. The AERCO part
numbers and model numbers are shown in the table below:
ProtoNode Model AERCO P/N Model Number
RER 64084 FPC-N34-103-126-0645
LER 64085 FPC-N35-103-401-0646
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, and Metasys N2
•The A Bank DIP switches on the ProtoNode RER-R 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 B.2 for the full range of addresses to set Nod-ID/Device Instance..
2.3.2 Setting the Serial Baud Rate (DIP Switch B0 – B3) for BACnet MS/TP & Metasys N2
•Setting the serial baud rate to match the baud rate provided by the Building Management
System can be done through DIP Switches B0 – B3 for BACnet MS/TP.
•Metasys N2 is always defaulted to 9600 baud and the B bank is disabled.

*NOTE:
The first sixteen profiles in the chart above (Section 2.3.3.1) require that DIP
switches A1 through A8 be set to OFF, which is the default setting, so those
switches do not need to be accessed for those configurations (and so are not
shown in the above chart). However, the last two profiles do require that DIP
switch A1 be set to ON, so for those two profiles, DIP Switch A1 needs to be
changed to ON (A2 through A8 remain in the OFF position).
A photograph showing the DIP switch locations inside the unit is on the next page.

The S-Bank DIP switches are accessible through the top cover. However, the cover must be
removed to access the A1 through A8 switches. To remove the cover, pull it from the unit while
holding onto the 6 pin Phoenix connector.
IMPORTANT!
Do not hold the wall mount tabs when removing the cover as these

3.2 ACS/BMS II/BMS Wiring Connections to ProtoNode RER and LER
•When an ACS, BMS II, or BMS is being used, an RS-485-to-RS-232 converter will be required to
connect it to the ProtoNode’s RS485 port (green 6-pin Phoenix connector).
•Refer to Figures 5 and 6 to locate the internal RS-232 connector JP12 (BMS) or JP5 (BMS II/ACS) inside
the wiring area of the ACS/BMS II/BMS.
•If the AERCO RS232-to-RS485 Converter (part no. 124943) is used, the RS-232 side of the converter
contains a connector that plugs directly into header connector JP12 (BMS) or JP5 (BMS II/ACS).
•If a third party converter is used, connect the RS-232 Receive (RxD) and Transmit (TxD) wire leads to
the internal RS-232 connector (JP12 or JP5) as shown in Figures 5 and 6. DO NOT connect the wire
shield on this side of the converter.
NOTE
If a third-party RS232-to-RS485 Converter is used, consult the manufacturer’s instruction manual for signal
polarity.
•On the RS-485 side of the converter (Figure 5 to Figure 7), connect the wire leads as follows:
o Connect the TD B (+) terminal to the ProtoNode’s RS485+ Port.
o Connect the TD A (-) terminal to the ProtoNode’s RS485- Port.
o Connect the GND terminal to the ProtoNode’s RS485 Frame GND Port.

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

related “system error” shown in the error screen of the RUI interface to AERCO International for
evaluation.
The RX LED will flash when a message is received on the socket port.
The TX LED will flash when a message is sent on the socket port.
This is the power light and should show steady green at all times when the ProtoNode LER is powered.
