CAN Keypad CK-M12 29.10.2019 | Version 1.1 | Quick Start Manual Bosch Motorsport 1 Introduction The CAN Keypad CK-M12 allows for simplification of the dashboard by offering 12 buttons and 9 additional wired inputs to be evaluated and transmitted via CAN bus to other devices on the bus. Each button has an individually addressable LED indicating ring that can be used to acknowledge a button press event, indicate status of a device, or alert the driver to a fault condition. No special configuration software is needed, all feedback logic is done by PBX, DDU or ECU.

Getting started | en 5 Bosch Motorsport Quick Start Manual 29.10.2019 | Version 1.1 | 2 Getting started The following supplies are required to use the CK-M12: – CK-M12 – Engine controller, data logger or related CAN enabled device – Appropriate harnessing to connect all devices, note that the CK-M12 does not contain a termination resistor. These steps are recommended to get started with the CK-M12: – Verify the resistance across CANH and CANL is equal to 60 ohms with a multimeter when the system is powered off. If 60 ohms is not found, check the CAN termination and refer to the wiring diagram in section three. – Configure the CAN enabled device of choice to read the CAN messages from the CK-M12. – Provide power to the CK-M12 and verify CAN communications between the CK-M12 and CAN enabled device. – Transmit indicator CAN messages for color and brightness to the CK-M12 and verify response.

Digital Inputs 1 to 9 are not intended to accept voltage! Additionally a maximum resistance to ground of 100 Ohm must be respected for proper function of digital inputs.

Wiring | en 7 Bosch Motorsport Quick Start Manual 29.10.2019 | Version 1.1 | The CK-M12 Sport does not include CAN termination on board. Proper CAN termination must be included in the wiring harness at each end of the bus. A daisy chain style bus must be constructed with stub lengths for added devices kept to under 1 foot (0.3 meters). Figure 3 shows a correctly constructed CAN bus with termination. Shielding is not required and the CK- M12 does not offer a shield wire. However, if another module on the CAN bus offers a shield pin, it is recommended to use it. Figure 3.2: Example CAN bus with proper termination and shield concept

CAN Keypad CK-M12 29.10.2019 | Version 1.1 | Quick Start Manual Bosch Motorsport 6 CAN Communications The CK-M12 transmits 1 CAN message that provides the status of each button and digital input, and receives 1 message to configure the indicating ring color for each button and the overall keypad brightness. The default baud rate is 1,000 kbps, however, other baud rates and IDs can be achieved through custom configuration by Bosch Motorsport. Notice! The brightness value MUST be sent to see any indicator feedback. Colors 9 to 15 will not be visible when using brightness value 1.

CAN Keypad CK-M12 29.10.2019 | Version 1.1 | Quick Start Manual Bosch Motorsport 7 Example Usage - PBX The CK-M12 is designed to be used in conjunction with the PBX190/90 power controllers, below is a simple example showing how to configure the keypad to switch on a high side output when a button is pushed. In this example the indicating ring will toggle between 0 (black/off) and 6 (blue) when the button is pushed. The values shown in the blue boxes are representing the default value for each of the blocks. 15 6 0 Figure 7.1: Momentary Switch Implementation Figure 7.2: Toggle Switch Implementation

CAN Keypad CK-M12 29.10.2019 | Version 1.1 | Quick Start Manual Bosch Motorsport 8 Example Usage - DDU The CK-M12 can be used with a DDU for various functions using simple math channels. In this example the DDU 7 will be controlling indicator 1 on the keypad based on the state of button 1. In the case that the button is pushed the math channel will return 4 (green). If the button is released it will return 13(dimmed blue). The corresponding 4 bits of 0x801 are filled with the math channel CKM_Ind1 to be transmitted to the keypad.
