Robot Signal Light

From Team 449 Wiki

(Redirected from Robot signal light)

The robot signal light (RSL) is a component of the electronics board that indicates the current state- functionality and competition mode- of the robot. The RSL is connected directly to the roboRIO. Due to the important information it provides with respect to the robot, an FRC team is not allowed to compete without a functioning signal light.


The end of the RSL's two-pin connector must be cut off.

The end of the two-pin connector is then inserted into the port on the roboRIO labeled RSL. It is not connected to the power distribution panel itself.
