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 (Daktronics part number W-
1242). See
Figure 16 for the location of the fiber connector on a
16-column driver. This method requires a signal converter
between the All Sport console‟s scoreboard output and the fiber
optic cable (not provided by Daktronics).
Multiple Driver Connections
Models in the FB-2350 scoreboard line require multiple drivers in each scoreboard section,
and use a master/slave driver system. Master and slave drivers function identically, but slave
units lack the power termination block and signal surge suppression card. When one section
has multiple drivers, they simply plug into one another, and this is done at the factory.
4.5 Power/Signal Connections Between Sections
A six-cable harness extends from the middle of the lower (statistics) section. Before the upper
(clock/score) section is mounted in place, these cables must be routed through the entrance
hole in the bottom channel of the upper section.
After the clock/score section has been secured to the mounting structure, open the
appropriate front or rear access panel to reach to the master driver enclosure, remove the
enclosure cover, and then connect each 9-pin plug to their matching jacks on the driver.
Note: Models FB-2352 & FB-2354 will also have a 3-pin plug (P44) to connect to the
power breaker enclosure (J44). Refer to Figure 13 .
4.6 Lightning Protection
The use of a disconnect near the scoreboard to completely cut all current-carrying lines
significantly protects the circuits against lightning damage. In order for this system to
provide protection, the power must be disconnected when the scoreboard is not in use.
The control console should also be disconnected from power and from the signal junction box
when the system is not in use. The same surges that may damage the scoreboard‟s driver can
also damage the console‟s circuitry.
