Daktronics FB-2500 Modular LED Football Scoreboard - Manual (Page 20)

14 Electrical Installation
Fiber Optic
Another common signal communication method is fiber optic
cabling. A minimum cabling of multi-mode, 62.5/125 um, and 2-
core fiber cable is recommended (part # W-1242). The fiber optic
cable is terminated to a male ST-type connector and plugged into
the mating J26 FIBER jack on the driver (Figure 16). This method
requires a signal converter between the All Sport console’s
scoreboard output and the fiber optic cable (not provided by
Daktronics).

* For HOME T.O.L. sections built prior to September 2013, the digit connects to J14 on
A1/PS1. For GUEST T.O.L. sections, the digit connects to J15 on A1/PS1. Backlit/
electronic captions for either section connect to J42B.
The T.O.L., DOWN, and QTR sections may have up to four connections:
 Route the 9-pin plug into the adjacent section and connect to the appropriate jack on
the primary (A1) driver.
 Route the 2-pin plug into the adjacent section and connect to the appropriate jack on
the Power Supply (24"+ white LED digits or 36"+ red/amber LED digits only).
 If the section includes a backlit or electronic caption, a 5-pin plug must be connected
to the power/signal interconnect cable coming from the primary (A1) driver.
 A ribbon cable must be connected between the last mod of the DOWN and BALL ON
electronic captions to the first mod of the TO GO and QTR electronic captions.
