#### WARNING:

* Don't drop the Logger onto the USB Connector with a plug-in USB Cable.
* Each End of the CAN bus must be terminated with a 120-ohm resistor acrosS CAN H and CAN L, and The Logger has dip switches inside that may be turned on if it is at the end of a CAN bus to allow the bus to be terminated easily.

#### WARNING:

* Don't short circuit or overload any Digital I/O, e.g. If using Digital Input or Output 3 to the power supply to power a K-Box or Rebel Dash, do not connect more than 1 K-Box to this output and be careful that no short circuit occurs.
* Overloading (I > 100mA) of Pin 10 (+4.5V Instrumentation) will result in a drop in the output voltage.
* Each End of the CAN bus must be terminated with a 120ohm resistor acroSs CAN H and CAN L, and The Logger has dip switches inside that may be turned on if it is at the End of a CAN bus to allow the bus to be terminated easily.
