Universal Serial Bus (USB)
A USB cable is used to connect the RCK3 hardware to the PC. This ensures that the RCK3
hardware has the best connection during the calibration process.
BMW RCK3 Connector Cable
Communication between the BMW RCK3 VCI and the BMW Motorcycle is through the RCK3
10 Pin connector that is connected to the bottom center of the RCK3 VCI.
Velcro Strap
The Velcro strap is used to tie the USB cable together with the DLC cable. This is done to
provide strain relief from the mini USB connector on the RCK3 VCI.
