NEXUS SOFTWARE - NSP
Installing the software
1. Insert the supplied USB Key into your
PC. If you have lost your USB key, you can
download the Haltech NSP software from the
DOWNLOADS section of the Haltech website.
2. If the window does not open automatically,
open My Computer and find the USB drive.
Double click on the USB drive icon.
3. Double click on the installer icon located in
the root directory of the USB drive.
4. Once the Haltech NSP software is installed,
run the software.
Going Online with the ECU
1. Plug the supplied USB-C cable into the
USB-C Port on the front of the NEXUS R5.
2. The USB-C connection will power the ECU in
a low power mode.
This mode allows the user to connect
to NSP for map configuration and data-
log extraction without powering the ECU
completely. ECU inputs and outputs are
disabled in low power mode.
3. NSP will recognise the ECU automatically.
4. Click File/Open to choose your base map.

Setting up Wi-Fi communications
Wi-Fi communications can be enabled using
NSP in the Wi-Fi Module Settings.
When disabled, the module is held in an OFF
state and is completely inactive.
To set up your Wi-Fi connection follow these
steps:
1. Open NSP and connect to your NEXUS R5 via
the supplied USB-C cable.
2. Click on Connections in the feature tree and
enable the Wi-Fi module setting.
3. Under Connections click on Wi-Fi to setup
your SSID and password. Your SSID must be at
least 1 character and your password must be at
least 8 characters.
4. Press Apply.
5. With the ECU powered up on main power
go to your computer’s Network settings and
connect to your NEXUS R5 by selecting your
chosen SSID and typing in your password.
NOTE: The ECU must be powered on main
power for Wi-Fi communication. Up to two
computers may be connected to an ECU over
Wi-Fi and one over USB-C at any one time.

NEXUS R5 WIRING
Main Power
The NEXUS R5 must be connected to battery
positive and battery negative at all times for
correct operation.
• Connect the NEXUS R5 to the positive battery
terminal via the supplied RED SurLok connector
using 1AWG cable and to the negative battery
terminal via the black SurLok connector using
1AWG cable.
There is an internal 32VDC 200A Positive Inline
Fuse inside the ECU for overcurrent protection.
NOTE: the fuse is not a user-serviceable part.
An ignition switch input must be wired to the
NEXUS R5 to turn the unit on.
There are two ways to provide an ignition switch
signal:
• Method 1: Connect the power for ignition
switch on pin A26 to one side of the ignition
switch, and connect the ignition switch input on
pin A13 to the other side of the switch.
This way, when the ignition switch is closed, the
ECU will see a +12V signal on the ignition switch
input and power up the ECU.
• Method 2: instead of using the power for
ignition switch pin, the hot side of the ignition
switch can simply be wired to any constant +12V
source, such that a +12V signal is detected on
the ignition switch input to power up the ECU.
This power for ignition switch provides a very
low current constant +12V signal and must only
be used to provide a signal back into the ignition
switch input.
The battery ground pins on the NEXUS R5 are
NOT used to ground the ECU and should not be
connected to battery negative or the chassis.
The battery ground pins are capable of 3A
current per pin and are directly linked to the
battery negative stud internal to the NEXUS R5.
These pins are for shielding or to ground low
current CAN devices (e.g. keypads) and digital
sensors.
There are two sensor +5V pins (A and B) for
sensors, and two signal ground pins (A and B).
Each is capable of 200mA and can be used in
any order, e.g +5V supply (A) and signal ground
(B) can be wired to the same sensor.
