Step 1: Download, Install & Configure the Software

Step 1

Download, Install & Configure the Software

This is a good time to:

Unbox the HEX ezCAN.
Decide what and how many accessories you will be installing, and their requirements. Must some accessories be connected in a specific manner and/or to specific power circuits? As an example, low-powered ‘smart’ accessories must typically be installed on the ezBUS (White) power circuit.
Read the Installing for Life section of the HEX ezCAN User Manual (downloadable from here), and evaluate your planned installation according to the guidelines in that section.
Register your HEX ezCAN (All you need to do to register the ezCAN is connect it to your computer using the supplied USB cable, meaning you can do it at the comfort of your desk.)

Step 2: Locate the Battery and XDWA (Alarm) Connector

Step 2

Locate the Battery and XDWA (Alarm) Connector

Needed tools:

10mm wrench or socket
T40 Torx driver (if rear sub-frame cross-brace is to be removed)

Access the vehicle battery and XDWA connector as follows:

Remove the rider and pillion seats.
If your bike has heated seats, unplug the seat-heating connectors under the rider and pillion seats.
Locate the bike’s battery (below, left).
Optional step: Cable routing can be eased slightly by removing the T40 Torx screws securing the rear sub-frame cross-brace, and removing the cross-brace (below, right).

Location of the battery

Location of rear sub-frame cross-brace

Depending on whether your bike has the optional BMW anti-theft alarm fitted, the XDWA connector will be seen in one of two configurations:

If your motorcycle has the BMW anti-theft Alarm:
The XDWA connector will be plugged into the alarm module.

With optional BMW anti-theft alarm fitted

If your motorcycle does not have the BMW anti-theft Alarm:
A resistor plug will be connected to the XDWA connector.

Without optional BMW anti-theft alarm fitted

Step 3: Plug the HEX ezCAN into the Bike's CAN-BUS

Step 3

Plug the HEX ezCAN into the Bike's CAN-BUS

Unplug the XDWA connector from the anti-theft alarm module or resistor plug as follows:

Pull the small white locking tab away from the connector in the direction of the wiring run.
Depress the tab to release the locking mechanism.
Pull the XDWA connector free of the alarm module or resistor plug by grasping the connector body. Do not pull on the XDWA connector wiring.
The procedure to connect the HEX ezCAN to your bike’s CAN-bus depends on whether a BMW anti-theft alarm is fitted:
– If your motorcycle has a BMW anti-theft alarm, connect the male ezCAN CAN-bus connector to the female BMW XDWA connector, and connect the female ezCAN CAN-bus connector to the BMW alarm module.
– If your motorcycle does not have a BMW anti-theft alarm, connect the male ezCAN CAN-bus connector to the female BMW XDWA connector, and connect the BMW resistor plug to the female ezCAN CAN-bus connector.

IMPORTANT: If the BMW XDWA connector seems difficult to release, do not force it. The videos below show you how to release the connector’s locking mechanism easily.

Step 4: Connect the HEX ezCAN to the Bike's Battery

Step 4

Connect the HEX ezCAN to the Bike's Battery

There are a few possible locations in which you can install the main body of the HEX ezCAN, and different ways in which you can route the cables.
HEX ezCAN device location and cable routing depends on a number of factors, including your personal preference.

Ensure that the wiring is routed safely and securely, in a way that does not allow it to chafe or pinch. Where needed, secure all wiring to frame tubes or other components using the cable ties supplied with the HEX ezCAN installation kit.

WARNING: For safety reasons, always disconnect the negative battery terminal first, and re-connect it last.

Start the installation by locating the main body of the HEX ezCAN in a place that allows straightforward, logical wiring runs. We recommend installing the HEX ezCAN main body behind the rear sub-frame cross-brace (image below), as this allows easier access for firmware updates and diagnostics. Alternatively, install the main body under one of the rear sub-frame side panels (right).
Disconnect the negative wiring harness terminal from the negative battery pole.
Disconnect the positive wiring harness terminal from the positive battery pole.
Connect the terminal on the orange ezCAN power cable, and the bike’s positive wiring harness terminal, to the positive battery pole.
Connect the terminal on the brown ezCAN power cable, and the bike’s negative wiring harness terminal, to the negative battery pole.
Tidy the CAN-bus and battery cable routing. Secure all loose cables using the cable ties included in the HEX ezCAN installation kit.

Note: The HEX ezCAN’s status LED should be solid green for approximately a minute after connection to the battery. After this time, the HEX ezCAN enters Sleep Mode, and there will be no LED activity until the bike’s ignition is switched ON.

Connect the HEX ezCAN to the positive battery terminal, then to the negative battery terminal.
Tidy and secure the cables. Make sure you have easy access to the four power circuit plugs.

Step 5: Connect the Accessories, using Colour Coding

Step 5

Connect the Accessories, using Colour Coding

The HEX ezCAN installation kit includes four two-wire stub connectors with male connection terminals, orange power wires and black ground wires.

The following parts are also included:

4x pulse-width modulation (PWM) terminal wires (orange with white tracer)
4x rubber blanking seals

If the accessory to be connected to a power circuit has three wires, convert a two-wire stub connector to a three-wire connector as shown in the Connecting 3-wire LED lights section of the HEX ezCAN User Manual (downloadable from here).

If the accessory to be connected to a power circuit has two wires, seal the stub connector’s empty terminal cavity as shown in the Connecting 2-wire accessories section of the HEX ezCAN User Manual.

If any of the HEX ezCAN’s power circuits will not be used, we recommend that you connect a blanking plug to the output plug of each unused circuit.

Connect the male terminal of each stub connector to the relevant female HEX ezCAN power circuit connector (below).

Connecting a 2-wire accessory to a HEX ezCAN stub connector:

Connect the accessory’s ground/Earth wire (this is usually, but not always black or brown) to the ground wire of a HEX ezCAN stub connector.
Connect the accessory’s power wire (this is usually, but not always red) to the 12V power wire of a HEX ezCAN stub connector.

Connecting a 3-wire accessory to a HEX ezCAN stub connector:

Connect the accessory’s ground/Earth wire and power wire as described above.
Connect the accessory’s PWM control wire to the dual-colour (solid colour+tracer) wire of an ezCAN stub connector.

Connecting low-power smart accessories to a HEX ezCAN stub connector:

Read the HEX ezBUS and Configuring HEX ezBUS functionality sections of the HEX ezCAN user manual (downloadable from here) for detailed information on how to use ezBUS functionality.

If you are installing ‘smart’ accessories (that is, low-power accessories capable of intelligent input and control through the HEX ezCAN’s LIN bus), note the following:

Smart accessories (including the HEX ezSWITCH) must only be connected to the HEX ezCAN’s ezBUS (white) power circuit. Smart accessories will not work if connected to the red, yellow or blue circuits.
The ezBUS (white) power circuit can accommodate any odd or even number of individual accessories, to a maximum of fifteen.
A selection of HEX ezBUS adaptors and connectors is available, allowing you to connect smart accessories quickly and easily. See the ezBUS Accessories section of the HEX Innovate online store for details.

Read the HEX ezBUS and Configuring HEX ezBUS functionality sections of the HEX ezCAN user manual (downloadable from here) for detailed information on how to use ezBUS functionality.

Note that if the white circuit is set to ezBUS mode, its fuse trip limit is set to 15 Amps by default. If needed, ezBUS PWR functionality can be used to increase the white circuit’s current capacity to a maximum of 30 Amps in ezBUS mode. See the relevant section of the HEX ezCAN User Manual for details.

IMPORTANT: If the stub connectors included in your HEX ezCAN installation kit do not have orange power wires, but instead have colours that match the colouring of the HEX ezCAN power circuits (as seen below), always connect like-to-like (red stub connector to red power circuit, blue stub connector to blue power circuit, and so on.)
