A system for detecting a type of hydraulic device. The system includes a hydraulic device. The system also includes a power supply having an engine and a controller. The controller is configured to detect a voltage of a signal from the hydraulic device, to categorize the signal as a type of signal of multiple types of signals based on the voltage, and to control a hydraulic output based on the voltage and the type of the signal.

1. A method for modifying a signal from a hydraulic device electrically connected to a power supply, the method comprising: detecting, using a controller, a voltage of the signal from the hydraulic device;categorizing the signal as a type of signal of a plurality of types of signals based on the comparing the voltage for the signal to possible voltage values of hydraulic signals;comparing the voltage to a first threshold voltage; anda) applying a first adjustment to the voltage when the voltage is greater than the first threshold voltage and less than a second threshold voltage; orb) applying a second adjustment to the voltage when the voltage is greater than or equal to the second threshold voltage. 2. The method of claim 1, wherein detecting the voltage of the signal from the hydraulic device comprises detecting the voltage of the signal from the hydraulic device before an engine of the power supply is turned on. 3. The method of claim 1, wherein the hydraulic device comprises a hydraulic crane. 4. The method of claim 1, wherein the first threshold voltage is less than the second threshold voltage. 5. The method of claim 1, wherein applying the first adjustment to the voltage comprises applying an offset to the voltage. 6. The method of claim 1, wherein applying the second adjustment to the voltage comprises changing between a negative proportional signal and a positive proportional signal. 7. The method of claim 1, comprising applying no adjustment to the voltage if the voltage is less than or equal to the first threshold voltage. 8. The method of claim 1, comprising controlling a hydraulic output based on the voltage, the first adjustment to the voltage, the second adjustment to the voltage, or some combination thereof. 9. The method of claim 8, wherein the hydraulic output comprises a quantity of hydraulic fluid. 10. The method of claim 1, comprising categorizing the signal as a normal signal, a step signal, a positive proportional signal, an offset step signal, a negative proportional signal, or some combination thereof. 11. A power supply comprising: one or more tangible, machine-readable media having instructions encoded thereon for execution by a processor, the instructions configured to cause a controller of the power supply to at least:determine a voltage of a signal from a hydraulic device;categorize the signal as a type of signal of a plurality of types of signals based on the comparing the voltage for the signal to possible voltage values of hydraulic signals; andcontrol an output based on the voltage and the type of the signal. 12. The power supply of claim 11, wherein the instructions further comprise instructions to: compare the voltage to a first threshold voltage;apply a first adjustment to the voltage when the voltage is greater than the first threshold voltage and less than a second threshold voltage; andapply a second adjustment to the voltage when the voltage is greater than or equal to the second threshold voltage. 13. The power supply of claim 12, wherein the instructions further comprise instructions to apply no adjustment to the voltage if the voltage is less than or equal to the first threshold voltage. 14. The power supply of claim 12, wherein the instructions to apply the first adjustment to the voltage comprise instructions to apply an offset to the voltage. 15. The power supply of claim 11, wherein the plurality of types of signals comprise one or more of a normal signal, a step signal, a positive proportional signal, an offset step signal, or a negative proportional signal.
