Refer to the QuickLIT website for the most up-to-date version of this document.
Application
Important: NIEx9s are compatible with Metasys® system Release 7.0 and later. You may apply the dual trunk
integration feature to NIEx9s purchased prior to the current release by using the NIEx9 Driver Manager
tool. For information on how to apply the latest package and license files that support dual trunks, refer
to the NIEx9 Driver Manager Application Note (LIT-12011919).
The Network Integration Engine (NIE) 39 and 49 are web-enabled, Ethernet-based, supervisory devices that integrate
the Metasys Building Management System to other standard building management communication technologies.
Integrations include the BACnet® protocol, LONWORKS® network, N2 Bus protocol, Modbus®, Meter-Bus (M-Bus,
European Standard EN 1434-3), KNX, and other third party proprietary protocols for monitoring and supervising a
wide variety of HVAC, lighting, security, fire, electrical and thermal measuring and access control equipment.
For the Modbus and M-Bus protocols, one NIE39 or NIE49 can support two integrations: two Modbus, two M-Bus,
or one of each, significantly expanding the engine's flexibility. See Table 10 for a list of all supported dual trunk
applications.
Important: The NIEx9 is shipped with a license and driver for the communication protocol that was ordered. If you
re-image the engine, the license and driver are deleted and the engine is not able to communicate with
the required protocol. If you need to re-image the engine, use the NIEx9 Driver Manager first to preserve
the protocol driver and license file before you re-image. For details, refer to the NIEx9 Driver Manager
Application Note (LIT-12011919).
This document describes how to install an NIE39 or NIE49, which is referred to collectively as NIE, unless specified
otherwise. Figure 1 shows the components of the NIE.

Mounting
Location Considerations
Follow these guidelines when mounting an NIE:
• Ensure that the mounting surface can support the NIE and any user-supplied enclosure.
•
Mount the NIE in proper orientation (Figure 1).
• Mount the NIE on an even surface in wall mount applications whenever possible. If you must mount the NIE on
an uneven surface, be careful not to crack the mounting clips or NIE housing when tightening the screws. Use
shims or washers to mount the NIE evenly on the mounting surface.
•
Mount the NIE in areas free of corrosive vapors, and observe the environmental limitations listed in the Technical
Specifications section.
• Allow sufficient space for cable and wire connections and access to the data protection battery and End-of-Line
(EOL) switch (Figure 1).
• Do not mount the NIE where the ambient temperature may exceed 50°C (122°F).
• Do not mount the NIE on surfaces prone to vibration or in areas where electromagnetic emissions can interfere
with NIE communication.
• Do not obstruct the NIE housing ventilation holes.
• Do not mount power transformers below the NIE.
2NIE39/NIE49 Installation Instructions
On applications where the NIE is mounted inside a panel or enclosure, follow these additional guidelines:
• Do not install the NIE in airtight enclosures.
• Do not install heat-generating devices in the enclosure with the NIE that may cause the ambient temperature to
exceed 50°C (122°F).
Mounting the NIE
Wall Mount Applications
Use the holes in the three mounting clips for wall mount applications.
To mount the NIE on a vertical surface:
1. Ensure that all three mounting clips are inserted into the back of the NIE housing, pulled outward, and snapped
firmly into the extended position (Figure 3).
2. Mark the location of the three wall mount holes using the dimensions in Figure 2, or hold the NIE up to the wall
as a template and mark the locations.
3. Drill holes in the wall at the locations marked in Figure 2 and insert wall anchors (if necessary).
Figure 2: NIE Mounting Screw Hole Dimensions (mm/in.) and Mounting Area Requirements
4. Position the NIE, insert the screws through the holes in the mounting clips, and carefully tighten the screws.
Important: Do not overtighten the mounting screws. Overtightening the screws may damage the mounting
clips or the NIE housing.
DIN Rail Mount Applications
To mount the NIE on a DIN rail:
1. Securely mount a 20 cm (8 in.) or longer section of DIN rail horizontally and centered in the space.
2. Ensure that the bottom two mounting clips are pulled outward and snapped firmly into the extended position
(Figure 3).

in the Location Considerations and Mounting the NIE sections.
Wiring
Power Supply, Network, and Bus Connections
See Figure 1 for the location of NIE ports, modular jacks, and terminal blocks.
Depending on the model, an NIE39/NIE49 supports either an MS/TP field bus trunk, an N2 Bus trunk, or a LONWORKS
network trunk. All models support two vendor integrations, such as two Modbus, two M-Bus, or one of each. Or if a
KNX integration is required, three KNX IP Gateways are supported for one NIE39/NIE49. See Table 10 for a list of
all supported dual trunk applications. The rules, guidelines, and wiring considerations for each type of network or
field bus application are provided in tables of this document.
Power Supply
In North America, the NIE requires a dedicated Class 2, 24 VAC, 25 VA minimum power supply. Outside North
America, use a 24 VAC safety extra-low voltage (SELV) transformer at the appropriate rating. The minimum input
voltage for the NIE to operate properly is 20 VAC. Maximum power consumption is 25 VA.
FC Bus Port
MS-NIE391x-x and MS-NIE491x-x models support one N2 Bus, one Master-Slave/Token-Passing (MS/TP) Bus,
one Modbus RTU trunk, or one M-Bus on the Field Controller (FC) Bus port. Connect the trunk to the 4-wire terminal
block plug labeled FC BUS. See Table 1 and Table 2 for more information on bus rules and bus device limits.
Note: BACnet® MS/TP, N2, Modbus RTU, and M-Bus are different protocols with different network requirements.
Do not intermix devices from different protocols to the same FC Bus connection.
4NIE39/NIE49 Installation Instructions
FC Bus Modular Jack
The 6-pin modular jack labeled FC BUS is an FC Bus service port for MS/TP applications (only).
Note: Do not connect an N2 trunk to the 6-pin modular FC Bus jack.
Refer to the N2 Communications Bus Technical Bulletin (LIT-636018) or the MS/TP Communications Bus Technical
Bulletin (LIT-12011034) for additional information and guidelines on wiring devices on an N2 trunk or an MS/TP
trunk.
LON Port
MS-NIE392x-x and MS-NIE492x-x models support one LONWORKS network trunk. Connect a LONWORKS network
trunk to the 3-wire terminal block terminal labeled LON. The cable Shield (SHD) on the LON port is an open terminal
and is not connected in the NIE.
Serial Ports
The RS232C A and RS232C B serial ports (Figure 1) provide direct connection to a Modbus RTU or M-Bus network
using a standard 9-pin female data terminal equipment (DTE) to 9-pin female DTE null modem cable. Integration of
only one device is permitted.
If the RS232C A serial port is not used to integrate a vendor protocol, you can connect to a computer serial port to
browse to the NIE or to connect to a VT100 or a computer with a VT100 emulator and perform diagnostic procedures.
If the RS232C B serial port is not used to integrate a vendor protocol, you can use the port to connect to an external
modem. Refer to the Metasys® System Extended Architecture Direct Connection and Dial-Up Connection Application
Note (LIT-1201639) for more information.
USB Port
The port connects to an external flash drive that can store diagnostic information when the NIE is placed in diagnostic
mode. You can otherwise configure the USB serial port to use an optional, user-supplied external modem.
Ethernet Port
The Ethernet port, labeled ETHERNET, is an 8-pin RJ-45 network port (Figure 1) for connecting the NIE to Ethernet
networks. NIE39/49 engines can connect to Ethernet networks at 10 or 100 Mbps. Use this port for connecting a
Modbus TCP, M-Bus TCP, or KNX network.
Wiring the NIE
Important: Do not connect 24 VAC supply power to the NIE before finishing wiring and checking all wiring
connections. Short circuits or improperly connected wires may result in permanent damage to the
equipment.
Important: Use copper conductors only. Make all wiring in accordance with local, national, and regional regulations.
The NIE is a low-voltage (<30 VAC) device. Do not exceed the NIE electrical ratings.
Important: Do not remove the terminal block keys. The terminal block plugs and the terminal sockets are keyed
to fit together in the correct configuration only.
Important: Prevent any static electric discharge to the NIE. Static electric discharge can damage the NIE and void
any warranties.
Important: Make sure the building automation network wiring meets the specifications, rules, and guidelines in
the Power Supply, Network, and Bus Connections section in this document.
Mount the NIE securely before wiring the NIE. See the Mounting section.
5NIE39/NIE49 Installation Instructions
Follow these guidelines when wiring an NIE:
• Route the supply power wires and communication cables at least 50 mm (2 in.) away from the vent slots on the
sides of the NIE housing.
• Provide slack in the wires and cables. Keep cables routed neatly around the NIE to promote good ventilation,
LED visibility, and ease of service.
Wiring the NIE for N2, MS/TP, Modbus RTU, or LONWORKS Protocol
1. Connect the Ethernet cable to the RJ-45, 8-pin Ethernet port on the NIE shown in Figure 1.
2. If using an external modem, connect the modem to USB A using the proper cable.
3. Connect the Building Automation System (BAS) network cables to the appropriate ports.
For an N2, MS/TP, or Modbus RTU network, connect the 3-wire bus cable to the removable 4-terminal blue
plug labeled FC Bus (Figure 4).
Note: If an N2 or MS/TP is connected to the NIE, you must set the NIE EOL switches to the proper positions.
See the Setting the End-of-Line Switch section.
•
• For LONWORKS compatible networks, connect the 2-wire cable from the LONWORKS network trunk to the
removable 3-terminal blue plug labeled LON (Figure 5).
Note: The LONWORKS network trunk is available on the NIE3920-x and NIE4920-x models only.
Figure 4: FC Bus Terminal Block and Wiring Connections
Figure 5: LONWORKS Network Terminal Block and Wiring Connections
4. For Modbus RTU Protocol using the RS232C A or RS232C B serial port, use a cable to connect the
RS-232/RS-485 converter to the RS232C A or RS232C B serial port on the NIE.
6NIE39/NIE49 Installation Instructions
Note: The maximum cable length between devices connected though an RS-232 line depends on the baud
rate used. In general, it should not exceed 15 meters at 9600 baud.
5. Wire from the RS-485 terminal on the converter to the RS-485 port on the vendor device (Figure 6). The RS-485
bus is a two-wire network.
a. Connect the converter's + A terminal to the device's + (or A) terminal.
b. Connect the converter's - B terminal to the device's - (or B) terminal.
c. If the device has a Signal Ground or Reference terminal, connect this to the converter's CG2 terminal.
Figure 6: Connection Between Converter and Device
6. To add additional vendor devices, wire from one device to the next as shown in Figure 7. No more than two wires
may be connected to each terminal to ensure the daisy chain configuration. See Wiring Rules and Guidelines
for Network Integrations for the Modbus protocol.
Figure 7: Daisy Chained Devices
The completed wiring should look similar to Figure 8.
7NIE39/NIE49 Installation Instructions
Figure 8: Modbus Wiring Detail Overview
7. Connect the 24 VAC supply power wires from the transformer to the removable power terminal block plug on
the NIE (Figure 9).
Figure 9: 24 VAC Supply Power Wiring
Note: Power supply wire colors may be different on transformers not manufactured by Johnson Controls. Follow
the transformer manufacturer’s instructions and the project installation drawings.
8. Connect the 24 VAC supply power wires from the transformer to the converter. No additional external power
adapter is required. Connect the hot and common wires as desired. The NIE does not require an earth ground
connection.
Note: The 24 VAC power should be connected to all network devices so transformer phasing is uniform across
the devices. Powering network devices with uniform 24 VAC supply power phasing reduces noise,
interference, and ground loop problems.
Wiring the NIE for M-Bus Protocol
1. Connect the Ethernet cable to the RJ-45, 8-pin Ethernet port shown in Figure 1.
2. Connect from the RS232C A or RS232C B serial port on the NIE to the RS-232 connecter of the level converter.
Wire to terminals GND, RxD, and TxD as shown in Figure 10.
3. Wire from the M- and M+ terminals on the level converter (Figure 10) to the meters using a free (star, tree, or
line) topology. Specific cabling can vary depending on the topology and site. See Wiring Rules and Guidelines
for Network Integrations.
8NIE39/NIE49 Installation Instructions
Note: If the number of M-Bus unit loads or distances exceeds the specifications of a level converter, an M-Bus
repeater can be wired to the converter to increase the number of unit loads and distances. The converter
shown in Figure 10 is capable of handling up to 6 units loads, while other models can handle up to 100.
See NIE Ordering Information for a list of M-Bus devices.
4. Connect the 24 VAC supply power wires from the transformer to the removable power terminal block plug on
the NIE (Figure 9).
Note: Power supply wire colors may be different on transformers not manufactured by Johnson Controls. Follow
the transformer manufacturer’s instructions and the project installation drawings.
5. Connect the 24 VAC supply power wires from the transformer to the -/~ and +/~ terminals as shown in Figure
10.
Figure 10: M-Bus Level Converter
Wiring the NIE for KNX Protocol
1. Connect an Ethernet cable to the RJ-45, 8-pin Ethernet port shown in Figure 1.
2. Connect another Ethernet cable to the port on the front of the KNX gateway (Figure 11).
Note: Depending on the size of your network, you can use either a KNX Interface or Router as a gateway. The
Interface connects the NIE to a single KNX line, while the Router acts as both an Interface and a Line
Coupler over Ethernet to connect the NIE to the network, not to a single device.
9NIE39/NIE49 Installation Instructions

Setup and Adjustments
Data Protection Battery
The NIE is shipped with the data protection battery installed and connected. Do not disconnect the battery for any
reason other than to replace a defective battery.
The 24 VAC supply power to the NIE charges the data protection battery. At initial startup, the battery may require
a charging period of at least 4 hours before it supports data protection if power fails. Maximum protection (up to 3
consecutive power failures without recharging time) requires a 15-hour charging period.
The data protection battery slowly loses charge when 24 VAC power is removed from the NIE. If the battery completely
loses charge, the NIE real-time clock stops.
Whenever an NIE is disconnected from 24 VAC power for over 30 days, ensure that the real-time clock is set properly
(from the user interface) and that the NIE is powered long enough to recharge the data protection battery.
Powering on the NIE
After applying 24 VAC power, the NIE requires approximately 2 minutes to start up and become operational. See
the LED Test Sequence at Startup section.
Startup is complete and the NIE is operational when the (green) RUN LED is On steady and the (red) FAULT LED
is Off (Figure 14).
Important: Wait for the NIE to complete the start-up sequence and the RUN LED to go On steady before initiating
any other action on the NIE.
15NIE39/NIE49 Installation Instructions
Disconnecting Power from the NIE
When 24 VAC supply power to an NIE is disconnected or lost, the NIE is nonoperational, but the POWER LED
remains On and the data protection battery continues to power the NIE for approximately 1 to 5 minutes while volatile
data is backed up in nonvolatile memory. The RUN LED goes Off when data backup and shutdown are complete.
Important: The data protection battery must be installed and charged before disconnecting the 24 VAC supply
power.
Setting the End-of-Line Switch
RS485 serial protocol bus segments require proper EOL termination to reduce interference from signal bounce back
on the bus segment.
FC Bus (MS/TP and Modbus RTU) applications require a terminated device at each end of each FC Bus segment.
See the Wiring Rules and Guidelines for Network Integrations section for more information on EOL requirements
on an FC Bus.
N2 Bus applications require at least one terminated device on each N2 Bus segment, but two terminated devices,
one at each end of the N2 Bus segment, are recommended. See the Wiring Rules and Guidelines for Network
Integrations section for more information on EOL requirements on an N2 Bus.
The NIE is shipped with the EOL switch in the factory default, ON (up) position (Figure 12). See Figure 13 to determine
the appropriate EOL switch setting for the NIEs on N2 Buses, FC Buses, and Modbus RTU buses.

Troubleshooting
LED Status Indicators
The NIE models have up to 11 LEDs (depending on the model) to indicate power and network communication status.
Figure 14 shows the LEDs and Table 11 describes the LED indications.
16NIE39/NIE49 Installation Instructions
Figure 14: NIE LED Designations
Note: Some of the LEDs shown in Figure 14 are not used or displayed on some NIE models.
LED Test Sequence at Startup
During startup, the NIE automatically initiates an LED test to verify the operational status of the LEDs. Immediately
after connecting supply power, the following LED lighting sequence occurs:
1. The POWER, BAT FAULT, 10 LINK, FAULT, RUN, and PEER COM LEDs turn On, indicating that the operating
system (OS) is booting up. (After 2 seconds, the LEDs may change states depending on site-specific network
activity.)
2. The BAT FAULT, PEER COM, and FAULT LEDs shut Off. The RUN LED flashes to indicate that the NIE software
is loading.
3. The LEDs display the status of the NIE. When the RUN LED goes On Steady, startup is complete, and the NIE
is operational.
The total time to start the NIE depends on the size of the database and can take several minutes.
See Table 11 for more information on the NIE LEDs.
