# Pinouts: Rebel LT Logger

### The USB Connector The USB Connector is a USB Series “B” Receptacle Interface.


Pin No	Pin Function
Pin 1	VBUS USB supply voltage 5V
Pin 2	Data- line of USB this signal utilises NRZI line coding
Pin 3	Data+ line of USB this signal utilises NRZI line coding
Pin 4	Ground

{% hint style="danger" %} #### 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. {% endhint %} ### The OBD & INST Connector The OBD & INST Connector is a Male 25-pin Standard D Type Connector nut.


Pin No	Pin Function
Pin 1	Analog Input 3 - do not apply voltages outside of the -10 to +10V range
Pin 4	Analog Input 1 - do not apply voltages outside of the -10 to +10V range
Pin 5	Wake-Up pin to wake logger from sleep mode (for use, see Appendix 1)
Pin 6	CAN Bus 1 (Medium Speed Bus) Low Signal
Pin 7	CAN Bus 0 (High-Speed Bus) Low Signal
Pin 8	K-Line (1 wire bus) of ISO 9141
Pin 9	4.5-36V Supply Voltage
Pin 10	+4.5V Instrumentation Supply Voltage, ensure that the current drawn is not more than 100mA
Pin 11	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 12	Digital Input or Output 0 - Do not apply voltages outside the 0 to +12V range when used as an input. When used as an Output, ensure that the current draw is not more than 100mA. More information on the use of this pin can be found in Appendix 2 and 3
Pin 14	Analog Input 2 - do not apply voltages outside of the -10 to +10V range
Pin 17	Analog Input 0 - do not apply voltages outside of the -10 to +10V range
Pin 18	Analog Ground
Pin 19	CAN Bus 1 (Medium Speed Bus) High Signal
Pin 20	CAN Bus 0 (High-Speed Bus) High Signal
Pin 21	Ground
Pin 22	Power Ground
Pin 23	Digital Input or Output 3 (can also be used as a switched power supply +Vd). When used as an input, do not apply voltages outside of the 0 to +12V range
Pin 24	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

{% hint style="danger" %} #### 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. {% endhint %} ### The GPS Connector The Optional GPS Connector is a Male SMB Connector.
