Special Note to Users of Daktronics All Sport 4000 Series and Daktronics Pro Sport 6000
Control Consoles:
Current standard models in the Daktronics scoring and timing display lines are configured at the
manufacturing plant to operate with the All Sport Series 5000 Control Console. If you receive one
of these standard scoreboards, you may need to remove the address plug before your scoreboard
can properly receive signal. Simply unplug the address plug, P19, from connector J19 on the LED
driver. (The plug is typically looped into the connector cable harness.) If you have problems in
this regard, contact the Daktronics Help Desk or your project manager.
3.3 Segmentation and Digit Designation
Reference Drawings:
Segmentation, 7 Segment Bar Digit....................................................... Drawing A-38532
In each digit, certain LEDs always turn on and off together. These groupings of LEDs are referred to
as
segments , and each digit is divided into seven segments. The bar digit drawing, A-38532, shows the
number of each connector pin wired to each digit segment as well as the wiring color code used
throughout the display.
The electrical specification drawings for the individual scoreboards show the digit layout for each
hockey scoreboard; the number inside the lower portion of each digit indicates the "digit designation,"
that is, which driver connection is wired to that digit.
