There are 10
kinds of people:
Those who know binary and those that don’t.
Robot Signal Light (RSL)

ROBOT SAFETY LIGHT

Solid ON - Robot On
and Disabled

Blinking - Robot On and
Enabled

Off - Robot Off,
roboRIO not powered
or RSL not wired
properly.
Spike H-Bridge Relay

Motor


provides On/Off control
in both the forward and
reverse directions
Custom robot electronics

provides power to up to
2 circuits

connected to a relay
output of the roboRIO

powered from the Power
Distribution Panel.

Talon SRX Speed Control

CAN-enabled "smart motor
controller“

Controlled over CAN bus
or PWM interface

Accepts inputs from limit
switches, potentiometers,
encoders, or similar in
order to perform
advanced control such as
limiting or PID(F) closed
loop control

Status Light Quick Reference

Power

Green - Power is good

Amber - Brownout protection tripped, outputs disabled

Red - Power fault, check user rails for short circuit

Status

On while the controller is booting, then should turn off

2 blinks - Software error, reimage roboRIO

3 blinks - Safe Mode, restart roboRIO, reimage if not
resolved

4 blinks - Software crashed twice without rebooting,
reboot roboRIO, reimage if not resolved

Constant flash or stays solid on - Unrecoverable error

Status Light Quick Reference

Radio

Not currently implemented

Comm

Off - No Communication

Red Solid - Communication with DS, but no user code

Red Blinking - E-stop

Green Solid - Good communication with DS

Mode

Off - Outputs disabled (robot in Disabled, brown-out,
etc.)

Amber/Orange - Autonomous Enabled

Green - Teleop Enabled

Red - Test Enabled

