Figure 30: Modular Power/Signal Interconnections (Front View)
For sections that are too
far apart to use internal
interconnects, the signal may
be re-driven, or “daisy-chained.”
Typically, the Game Clock
section would receive primary
signal from the control location,
and signal cable could then
branch out to the HOME and
GUEST score sections. From
there, signal can be re-driven
once more to the DOWN/TO GO
and BALL ON/QTR sections. Refer
to Figure 31 for an example of
re-driving signal.
Note: For radio-controlled systems, the radio receiver may be located in one section,
while signal cable is routed to the other sections as needed.
Three-Section Tennis Models
The primary driver and power panel will be located in the top section. Refer to the
component location drawings attached to the product specification sheets listed in
Appendix A for exact driver locations.
Open access panels as needed to locate the coiled bundles of interconnect cable,
then route and connect the cables as described below and shown in Figure 32 .
1� Route the interconnect cable labeled P50 coming from the A2 driver in the middle
section up into the top section and connect it to the mating J50 jack coming from
the power panel.
2� Route one end of the other interconnect cable labeled P51 from the middle section
up into the top section and connect it to the mating J51 jack coming from the power
panel.
3� Route the other end of the interconnect cable labeled J52 from the middle section
down into the bottom section and connect to the mating P52 plug coming from the
A5 driver.
