# K-Box

### The CAN Connectors (2x DB9 CAN Connectors) The CAN Connectors are 1x Male and 1x Female 9-pin Standard D Type Connectors with nuts.


Pin No	Pin Function
Pin 1	Digital Output 4 or +4.5V Instrumentation Supply Voltage, ensure that current draw is not more than 100mA
Pin 2	CAN Bus Low Signal
Pin 3	Ground
Pin 4	Digital Input or Output 1 - Do not apply voltages outside of the 0 to +12V range when used as an input. When used as an Output, ensure that the current drawn is not more than 100mA. More information on the use of this pin can be found in Appendix 2 and 3
Pin 5	Power Ground
Pin 6	Digital Input or Output 3
Pin 7	CAN Bus High Signal
Pin 8	Digital Input or Output 2 - Do not apply voltages outside of the 0 to +12V range when used as an input. When used as an Output, ensure that the current drawn is not more than 100mA. More information on the use of this pin can be found in Appendix 2 and 3
Pin 9	4.5-36V Supply Voltage
