This post defines how to connect to and configure the Kelly KLS7230S controller on the 72V ONYX RCR.

It covers Bluetooth modules, AC Aduser setup, and how to access controller parameters.

  • Required before changing any settings
  • Defines how to read and write controller configuration
  • Applies to both Bluetooth and wired connections
  • AC Aduser is required for controller configuration and is not available on iPhone

Controller Connectivity Overview

The most reliable configuration method is a wired USB-to-RS232 connection on Windows.

* Bluetooth BLE can pair, but is not the standard method for AC Aduser controller programming.

Bluetooth Module Types

ONYX systems use two Bluetooth module types for controller communication.

  • White Bluetooth EDR module (classic Bluetooth)
  • Black Bluetooth BLE module (low energy Bluetooth)

Older ONYX bikes (V1.0 and V1.2) typically use the white Bluetooth EDR module, which does not support iPhone.

Newer models (V1.5, V1.75, LTD) use the black Bluetooth BLE module, which supports iPhone and Android at the hardware level.

For controller programming with AC Aduser:

  • EDR is the primary and required method on Android
  • BLE can pair but is not the standard method for controller configuration
  • Windows bypasses Bluetooth entirely using a wired connection

iPhone support applies to Bluetooth connectivity only. AC Aduser is not available on iPhone, so controller configuration cannot be performed from iOS.

All modules and the USB cable connect using the same JST SM 4-pin connector.

Wired Connection (Windows)

Use a USB-to-RS232 cable connected through the ONYX controller harness using the JST SM 4-pin connector.

  • Required for Windows-based configuration
  • Most stable connection method
  • Avoids Bluetooth pairing and connection issues
