Introduction 1-4
Radio Network
The Radio network is a standard communication method that uses radio waves at
high frequencies to transmit signal. The Venus
® 1500 Radio network has a maximum
distance of 450 meters (approximately 1,500 feet) outdoor and 150 meters
(approximately 500 feet) indoor. A nearly straight line-of-sight path must be
maintained between the Server Radio attached to the building and the Client Radio
connected to the display. A computer with a serial, RS232 communication port is
required. Refer to Section 3 and the Venus 1500 Gen 2 Radio manual, ED13932, for
additional information.
1.4 Display Overview

Shop Drawing, AF-3150-**x**-20mm-R or Amber ...... Drawing B-183660
Daktronics AF-3150 Galaxy
® displays are designed and manufactured for
performance, reliability, easy maintenance, and long life. The pixels have a 20mm
center-to-center spacing, and are lit using LEDs (light emitting diodes). A light
sensor on the front of the primary display is used for automatic dimming of the LEDs
based on the ambient light levels. The configuration of pixels depends on the model
of display ordered.
Refer to Drawing B-183660 for the approximate size, weight, and power
requirements for your model of display.
The Galaxy
®
model numbers are described as follows:
AF-3150-RRCCC-20-X-X(X)
AF-3150 = Outdoor 20 mm Louvered Galaxy Display
RR = Number of Rows High (16-48)
CCC = Number of Columns Long (Up to 144
Columns Standard)
20 = 20 mm pixel to pixel spacing
X = LED Monochrome Color (Red or Amber)
X(X) = PS – Primary-Secondary or S - Secondary
A typical display system consists of a Windows
®
based personal computer (PC)
running Venus
®
1500 software, a communication system, and one or more displays.
The displays are offered as single-face units, which are single-sided stand-alone
displays. They can become double-faced by mounting them back-to-back with a
second unit.
Venus
® 1500 is a software package that runs under Windows
®
98, ME ™ , NT ® 4.0,
2000, or XP Home/Professional operating systems on an IBM
®
-compatible
computer. Refer to the Venus ® 1500 controller operator’s manual (ED13530) for
installation and operation of the Venus
®
1500 editing station.
Refer to Sections 4.2 and 4.3 for the summaries of how signal and power are routed
through the displays.
