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.
