Re: Serial to CAN Gateway in new Black Jaguars?

Kevin,
The Jaguar controls average current by pulse width modulation but the pulses can only go between 0 volts and the battery terminal voltage (12 volts nominal.). Are you thinking of current sense? That is available through the CAN bus. There is a series resistor built into the Jaguar and the voltage drop across that resistor can then be used to calculate current through the device.
