Overview
WARNING
Risk of electric shock or equipment damage!
► Do not touch any live parts in the cabinet!
► Disconnect the power supply before making connections
to or removing connections from terminals of the
EAGLEHAWK NX controller or Panel Bus I/O modules.
► Do not reconnect the power supply until you have
completed installation.
► Due to the risk of short-circuiting (see Fig. 23), it is
strongly recommended that the EAGLEHAWK NX controller be supplied with power from a dedicated transformer. However, if the EAGLEHAWK NX controller is to
be supplied by the same transformer powering other controllers or devices (e.g., the PW M-Bus Adapter), care
must be taken to ensure that correct polarity is observed.
► Observe the rules regarding electrostatic discharge.

The two Ethernet interfaces can be used in either of two
different ways (the corresponding configuration is done in
COACH NX):
• "Separated networks" (factory default). In this scenario,
each of the two Ethernet interfaces must be activated and
located in a different subnet.
• "Switch functionality." In this scenario, one of the two
Ethernet interfaces is deactivated. The deactivated Ethernet interface now functions in the loop-through (daisychain) mode and can therefore be used to continue the
data line.
NOTE: During any power failure of the EAGLEHAWK NX,
the switching functionality is inoperative.

gateway address. If there is no gateway address physically
given by the Network Setting, then enter a gateway address
that relates to the IP address of the enabled Ethernet Interface. In Fig. 10, the gateway address is 192.168.1.1, hence
the IP address of Ethernet adapter 1 must be in the range of
192.168.1.2 to 192.168.1.255.

RS485 Interfaces
General
The EAGLEHAWK NX controller features two RS485
interfaces:
• RS485-1 (consisting of push-in terminals 24 [GND-1], 25,
and 26) is isolated and can be used for any RS485-based
communication protocol available within Niagara
Ecosystems, e.g.: Panel Bus, BACnet MS/TP, etc.
• RS485-2 (consisting of push-in terminals 29, 30, and 31
[GND-2]) is non-isolated (i.e. GND-2 is internally connected with terminal 1 [24V~0]) and can be used for any
RS485-based communication protocol available within
Niagara Ecosystems, e.g.: Panel Bus, BACnet MS/TP,
etc.
NOTE: It is imperative that the RS485-2 be powered by a

RS485-2 Bias and Termination Resistors
The RS485-2 interface is not affected by the aforementioned
three-position slide switch. The 550Ω bias resistors and 130Ω
termination resistor of the RS485-2 are thus always ON.

RS485 Standard
According to the RS485 standard (TIA/EIA-485: "Electrical
Characteristics of Generators and Receivers for Use in
Balanced Digital Multipoint Systems"), only one driver communicating via an RS485 interface may transmit data at a
time. Further, according to U.L. requirements, each RS485
interface may be loaded with a max. of 32 unit loads. E.g.,
CentraLine devices have as little as ¼ unit load each, so that
up to 128 devices can be connected.
BACnet MS/TP connections to the RS485 interfaces must
comply with the aforementioned RS485 standard. Thus, it is
recommended that each end of every connection be equipped
with one termination resistor having a resistance equal to the
cable impedance (120 Ω / 0.25 – 0.5 W).
RS485 systems frequently lack a separate signal ground wire.
However, the laws of physics still require that a solid ground
connection be provided for in order to ensure error-free
communication between drivers and receivers – unless all of
the devices are electrically isolated and no earth grounding
exists.
IMPORTANT
The cable length affects the communication rate. Table 6
provides a few examples.
(terminal 1)
In the case of new EAGLEHAWK NX controller
installations, we strongly recommend using a separate
signal ground wire. Doing otherwise may possibly lead
to unpredictable behavior if other electrically nonisolated devices are connected and the potential
difference is too high.
In the case of the installation of EAGLEHAWK NX
controllers in already-existent RS485 two-wire systems
(e.g., when replacing PANTHER and LION controllers
with EAGLEHAWK NX controllers), not using a
separate signal ground wire will probably have no
undesirable effects.
Table 6. Bit rate vs. max. cable length for RS485
Bit rate Max. cable length (L)
9.6 - 76.8 kbps 1200 m
*115.2 kbps 800 m
* In the case of configuration of RS485-2 for Panel Bus, the
communication rate is set to 115.2 kbps.
For information on wire gauge, max. permissible cable length,
possible shielding and grounding requirements, and the max.
number of devices which can be connected to a bus, refer to
standard EIA-485.
Modbus Connection
The EAGLEHAWK NX controller can function as a Modbus
Master or Slave. In general, the RS485 wiring rules must be
followed.
Wiring Topology
Only daisy-chain wiring topology is allowed.
MODBUS
MASTER
Other wiring topologies (e.g., star wiring, or mixed star wiring
and daisy chain wiring) are prohibited; this is to avoid communication problems of the physical layer.

Cables
See also section "EIA 485 Cable Specifications" on pg. 35.
Use shielded twisted pair cable J-Y-(St)-Y 2 x 2 x 0,8.
You must use three wires:
• One wire for D1 = Modbus +
• One wire for D0 = Modbus –
• One wire for the signal common
When using one pair for D1 and D0 and one wire of another
pair for the signal common, CAT5 cable may also be used.

For connection details, see section "Modbus Connection" on
pg. 43.
Shielding
Shielding is especially recommended when the Modbus cable
is installed in areas with expected or actual electromagnetic
noise. Avoiding such areas is to be preferred.
Use shielded twisted pair cable shielded twisted pair cable JY-(St)-Y 2 x 2 x 0,8 and connect the Modbus to a noise-free
earth ground – only once per Modbus connection.
RS485 Repeaters
RS485 repeaters are possible, but have not been tested by
Honeywell. Hence it is within responsibility of the installing /
commissioning person to ensure proper function.
NOTE: Each Modbus segment will require its own line

Modbus Compliance
As per the Modbus standard, the EAGLEHAWK NX controller
is a conditionally compliant "regular" Modbus device.
The EAGLEHAWK NX controller differs from an unconditionally compliant "regular" Modbus device in that it does not
support communication rates of 1.2, 2.4, and 4.8 kbps
(because these communication rates are not marketrelevant).
Physical Layer
