Fiber Optic Network
A fiber optic network is a standard communication method transmitting light (signal)
through a glass fiber. Fiber optic cable has a maximum length of 600 meters
(approximately 2,000 feet). A signal converter is needed to convert the computers
RS232 signal to fiber optic signal; a minimum of two fibers is required. Refer to
Section 3 for additional information.
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 connected to the computer and the Client radio
connected to the display. Refer to
Section 3 and the Venus 1500 Radio Manual,
ED13932, for additional information.

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 the drawings referenced above for the approximate size, weight, and power
requirements for your model of display.
The Galaxy
®
model numbers are described as follows:
AF-3155-RRCCC-20-RGB-X(X)
AF-3155 =
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
RGB =
LED Color (32,000 RGB)
X(X) =
PM (Primary-Secondary) or S (Secondary)
A typical display system consists of a Windows
®
based personal computer (PC)
running Venus
®
1500 software 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.
