4.2 Signal Summary
1. Data from the control computer, which runs Venus 1500 software, travels
via RS232, RS422, modem, fiber optic cable, radio signal, or Ethernet
signal into the enclosure by the display.
Figure 33: Primary/Mirror Interconnect Board
2. From the display enclosure, signal is sent
to the display controller via a quick
connect cable.
3. From the controller, the signal then travels
over 20-conductor ribbon cables from the
controller (J11 through J16 provide signal
out) to J2 on the driver of the first column
of modules in the display.
4. Data exits at J1 and is relayed to J2 of the
next driver board and so on, traveling down
the entire row of modules. This display
data is used to control the LEDs.
5. At the last column of modules a 20-
conductor ribbon cable from the J1 output
connects to a 31-pin quick connect output
board. Refer to
Figure 33
on the right.
6. For multiple face displays a quick connect
interconnect cable transfers data from the
primary display to the mirror display.
7. A 31-pin quick connect input board on the mirror display receives the signal
and transmits it to J2 on the first column of modules, via a 20-conductor
ribbon cable.
8. Data exits at J1 and is relayed to J2 of the next driver board and so on,
traveling down the entire row of modules in the Mirror face. This display
data is used to control the LEDs.
4.3 Power Summary
Reference Drawings:
Schem, AF-3112-8-32X***-34mm-Mono-PM .............. Drawing C-200002
The power routing for the display can be summarized as follows:
1. Incoming power terminates at the power termination panel. Before leaving
the panel, power is sent through a circuit breaker and an RFI electrical filter.
2. Power for the controller board passes through a transformer located on the
controller/power panel.
3. Depending on pixel count and color, power supplies (6.5VDC or 9VDC) are
used to power the modules. Power supplies are preset. Contact Daktronics
Customer Service for the proper settings.
4. The AF-3112 Galaxy displays use either red or amber LEDs for a
monochrome display. See
Drawing C-200002 for power supply wiring
information.
•
Each 9VDC power supply (A-1633) provides power to up to five
modules in a display that uses three amber LEDs per pixel.
•
Each 6.5VDC (A-1591) power supply provides power to up to five
modules in a display that uses two red LEDs per pixel.
