Signal Routing
Figure 17 shows how signal is routed through the display.
1� Signal enters the display through the Antenna and Wi-Fi router into the controller jack
J17A.
2� Signal travels from the Controller jack J13A to the light sensor (2).
3� From the controller jack J10, signal travels through a signal cable to Port A on the first
lower-left module (3).
Note: Consult the Electrical Layout drawing for signal routing details specific to your
display size.
4� From Port B on the first module, signal travels to the top-left module Port A (4a) and
travels from module to module via signal cables (4b), finally ending at the bottom-
right module (4c).
5� Signal from the primary display face travels from the Port B jack on the bottom-right
module to the Port A jack on the bottom-left module in the mirror face (5).
Controller Diagnostics
The Galaxy
®
eCCB controller is
located in the left portion of the
display (consult the electrical
layout drawing for exact location).
The controller receives incoming
signal from the control device
(smart device or tablet) and routes
that signal to the modules. The
controller has LEDs on it that can
be useful when troubleshooting
a communication issue. Figure 18
shows those LEDs.
