View source for The CAN-IN and IGNITE socket of Ubox V2

Ubox V2 has two new sockets on its panel: CAN-IN and Ignite:
==CAN-IN==

'''CAN-IN is used for trig power on.'''

'''CAN-OUT is a plain CAN socket.'''

Ubox V1 was not considered for 4WD when we designing it, and it has a [[The power button of Ubox#The power button of Ubox 75V/100V|independent power on control mechanism]]. So when people want to build a 4WD with Ubox V1, it is not so convenient. we didn't consider it carefully at that time, I'm sorry.

Ubox V2 makes 4WD easy, by separating CAN-IN and CAN-OUT socket, with one CAN bus cable, 4WD will work.

<br style="clear:both;">

Why we need to separate the IN and OUT? Because, Ubox supports momentary type button, the EN signal of the 12V power source is maintained by a MCU, so it can not self turn off when the 5V from the CAN cable is disappeared.  By discriminate the CAN-IN 5V, the MCU can give up the EN control, let the CAN-IN 5V to take control of the EN, the CAN-IN 5V is only used for trig on the Ubox. 

The '''logic''' of CAN-IN is, if it has a voltage upon it, this Ubox will power on(when battery plugged on),  it the voltage disappeared, this Ubox will off.

'''The CAN-OUT is just put out its own 5V to the out side,''' so when this(its own) Ubox power off, the 5V on the CAN-OUT will disappear.

What if I plugged CAN cable into CAN OUT which comes from the master ESC? The slave Ubox you plugged-in CAN cable can still work, but its own 12V will not work, all of its system working power will from your CAN cable input.

==Ignite==
The Ignite socket is hidden away because it has a battery voltage in it, this is often '''too high''' to be safe, so we hid it. '''Don not plug the power button in it.'''

The ignite socket is for the E-bike/E-scooter, to comply with their ignite key and voltage meter.

The ignite key returns the battery voltage back to ESC, ESC then powers on. 

The voltage meter measures the the battery voltage relative to GND.

So Ubox V2 provides GND, BATT+ and IGNITE, three pins. '''Short the BATT+ and IGNITE, Ubox will power on, release them, Ubox will power off immediately'''. 

Connect a voltage meter with GND and VABTT, the meter will indicates the battery voltage. '''Do not short the BATT+ and GND, it will blow the fuse''', yes we fused BATT+ pin.

The BATT+ pin is not designed for providing buck current, it is not suggested to draw more than 1A current from it.

For the relations between ignite key socket and power button we provided, please refer: [[The priority of power-on input of Ubox V2]].
