Sabertooth Dual 12A 6V-24V R/C motor driver Input spec

I need the [font=arial,sans,sans-serif]Sabertooth Dual 12A 6V-24V R/C Regenerative Motor Driver input specification. The technical documentation is very sparse.[/font]
[font=arial, sans, sans-serif]I want to control this driver with a microprocessor, so I need to know the input[/font][font=arial, sans, sans-serif]waveform specifications. The attached file shows the input relationship to the output RPM,[/font]
[font=arial, sans, sans-serif]but the axis is not labeled. It just says “input control”[/font]

[font=arial,sans,sans-serif][/font]
[font=arial,sans,sans-serif]I know this particular driver is for radio control, but unfortunately I ordered the wrong motor driver and I live in Malaysia, so I don’t want to wait a month to get the right one.[/font]
[font=arial,sans,sans-serif]I should be able to control this with a microprocessor if I have the right technical information. Any help with getting the input specification (corresponding to the radio receiver output)[/font][font=arial, sans, sans-serif]would be greatly[/font][font=arial, sans, sans-serif]appreciated.[/font]

The input from an Arduino-based board is RC PWM. You send commands to the Sabertooth the same way you would for an RC servo motor.
1500 is neutral, and decreasing to -500 increases the speed in one direction. Increasing from 1500 to 2500 increases the speed in the other direction.

If you’re still not sure, look up RC PWM signals.

Thank you CBenson! That was the answer.
