RESET and MOTORS
The RESET (red) and MOTORS (white) push-button switches on the Pioneer 2 Console affect the
microcontroller’s logic and motor driver systems. Both are under software control.
When pressed alone, RESET puts the microcontroller into its start-up state, disrupting any running program
or client connection. It also disables the drive motors—just as if you cycle Main Power. But, unlike a cold-
power restart, RESET preserves the contents of the Pioneer 2 microcontroller's RAM, so any user programs
downloaded in standalone mode get restarted.
The MOTORS pushbutton is NOT a power switch—it does not directly control
power to the motors. P2OS does and your standalone software must.
The MOTORS button and its associated green LED are under software control. Normally, Pioneer 2's
motors are disabled when not connected to a client, or when not running in joystick-drive or self-test mode,
when running a standalone program on the controller.
Pressing and releasing the white MOTORS button enables/disables the motors when connected with a
P2OS client. When first connected with a client, the motors remain disabled (LED flashes) until you press
and release the MOTORS button. The green LED should light continuously when the motors are enabled
and blink on / off when disengaged.
