4 digit (1-9999) display panel for a single circuit signal. Connect signal to the right most arithmetic combinator via a green wire. Will only work for signal counts between 1-9999. When a signal is "active" (1 or greater), the left and right most panels will display the signal being counted. Will not work with multiple input signals.
