# Connecting and powering the K-TCxx

However, K-TCxx is powered via the CAN and power connectors and designed with CiA® 102 pinout for the CAN bus and power to connect the device as simply as possible.

Most commonly, it will be powered from a reXgen Air or a Rebel Logger using the Multi Connect Cable or via ReXgen 1/2/IMU via its connectors, but you can also power it via pin 9 (4.5 to 36V) and pin 5 PowerGND of the 9-pin Sub D connectors. If connected via the multi-connect cable, the CAN 1 (MS) bus is also connected, allowing the Logger to record the data transmitted from the K-TCxx.

Warning:

* Several K-TCxx can be daisy-chained via the additional DB9 Connector. However, they must have power supplied separately via a power breakout in the cable, not via the Logger. It can also connect to other devices, such as the Rebel Dash.
