Display

Introduction

Displays are often used as a means of user input to set assist levels, view diagnostic information and rider information.

Note

Displays can communicate with ASI Controllers over CAN or TTL.

Wiring

Danger

The B+ Pin from ASI Controller outputs the battery voltage. Make sure the display is compatible with this voltage, or use the 12V output pin.

Warning

• Extreme care must be taken when wiring and connecting displays to the controller. Displays generally use 5 wires. One of these wires carry battery voltage to the display, and another from the display. If wired incorrectly, battery voltage could be applied to either communication pins, or shorted to ground. The result being at best a blown communication port and at worst a blown control board from drawing excessive current through it.

• If you are unsure of the pinout of the display or the controller, do not connect them together. Contact your display manufacturer to confirm the display wiring pinout and verify it against how you have wired it to the controller.

TIP

Make sure you verify continuity through the plug. When looking at the plug faces, the male pinout should mirror the female pinout.

CANTTL

Typical display wiring where the display is used to turn on the controller.

Typical display wiring, where an external switch is used to turn the controller ON/OFF.

Tip

ASI Strongly recommends connecting displays to Port 2 instead of Port 1. Port 1 should be used for PC connections.

Typical display wiring where the display is used to turn on the controller (Example: APT 750C 72V version, or EggRider connected to a system that peaks at 60V or less.)

Typical display wiring, where an external switch is used to turn the controller ON/OFF. Example: Eggrider connected to 12V supply because the system voltage is above 60V.

Configuration

Warning

Ensure vehicle is secured in-case the motor engages unexpectedly while manually configuring your display.

TIP

Make a backup copy of the parameter file often by saving it to file as shown before. It can be sent to ASI for support or you can revert if strange behaviour occurs.

With the display connected to the controller

1. Enable Communications configuration vector bit 10 (Enable Ebike).
2. Set the Display protocol if using port 1 and Display protocol2 if using port 2 to your displays communication protocol.
