The controller is mounted to the inside back of the display cabinet near the power
and signal jacks. The display controller receives information from the ticker input,
interprets it, and activates the corresponding LEDs accordingly. The controller also
has a set of eight switches by which an address (from zero to 15) can be set using
standard binary code (refer to Section 4.3). Display controllers are found only in
“master” displays.
