# Configuring a Stacklight

The stacklight can be configured to display the I/O signals from the tool.

The stacklight can be customized as follows:

- A stack of four lights. One optional light can be added to this stack. You can also customize the order and the color of lights.

- Two positions, A and B, which can be customized with indicator lamps or switches.

- A buzzer placed on the side of the box that has a fixed frequency of 3000 Hz. The buzzer can be configured to activate on any tightening tool signal.

- Two external outputs, two external inputs and a connector for external power.

To set up the Stacklight, refer to the CAN converter Product Instructions.
