STANDARD FEATURES
The Mapboard Display Control System is a microprocessor based assembly of electronics for the operation of a large number of incandescent lamps or LED’s within a mosaic or other type of large display board. The state of each display point is maintained by the system until changed via its manually operated keyboard or by a supervisory computer. The system incorporates all necessary lamp drivers, memory, control logic and communication logic. Our basic system has the following standard features:
* Control of up to 2048 individual display points each capable of driving up to 100 milliamps from up to 28 VDC.
* Each of the display points can be in one of the following states:
- OFF
- ON
- FLASH (1.0 sec OFF, 1.0 sec ON)
- BLINK (0.25 sec OFF, 0.25 sec ON)
- DIM (50% Intensity)
- MODULATE (Modulating Intensity, 0%, 25%, 50%, 75%, and 100%)
* Display point status can be examined or updated via a remote Keyboard/Display (Manual operation) or via any one of three serial asynchronous RS232C interfaces (Run/Lock Operation).
* Power Fail Recovery - Following a power failure display conditions are reconstructed as they were before power went out. Data retention exceeds ten years.
* Visual Lamp Test - All points can be turned ON for a visual check without affecting normal status.
* Monitoring of up to four +5 volt logic power supplies and four lamp power supplies.
