Mechanical Specification Drawings ......................... Refer to Appendix A
Displays in the DataMaster Parking Garage display series are made up of two main
components: the circuit boards that make up the digits and the driver enclosure.
Display digits are made up of a single circuit board that is mounted to the face plate
of the display.
Each host display contains an enclosure that includes the following parts:
• Display driver
• 24V DC power supply
• Signal/power input terminal locks
The DataMaster Parking Garage displays are front-access, meaning that the displays
open from the front for all service. The face panel is held to the display by a variable
number of screws depending on the display size and type. Removing the faceplate
will allow access to all the internal components. Refer to the Mechanical
Specification Drawings for locations and numbers of screws in the panel.
