Setup

Couple shutdowns and brakes for M1 and M2

Check this if you want a shutdown set on M1 to also shut down M2, and vice versa. Brakes will also be linked. This is desirable especially for differential drive applications of User Mode.

Analog

Reads analog voltages, and scales them using the calibration specified.

RC

Reads RC servo pulses, and scales them using the calibration specified.

Serial RX

Receives serial data.

Packet/Simplified Serial

Receives Packet Serial and Simplified Serial commands. This is the default.

The USB Packet Serial address may be customized.

SyRen Traditional Simplified Serial

Receives traditional single-byte SyRen Simplified Serial commands.

This can control only M1.

Sabertooth Traditional Simplified Serial

Receives traditional single-byte Sabertooth Simplified Serial commands.

This can control only M1 and M2.

Relay To

Sends copies of received serial data over the selected TX lines.

Among other things, this lets you use the Sabertooth as a USB-to-serial converter.

Serial TX

Outputs serial data. If you are using Serial RX and issue a command that requires a response, the response will be sent over the Serial TX line.

Indicator

Outputs based on whether or not a particular User Mode output is positive or not. This lets you power external LEDs on high current or temperature, for instance.
