Introduction 2
RS-232 Network
RS-232 (EIA/TIA-232-E) is a standard communication interface that employs a single-ended serial
transmission scheme that uses a maximum cable length of 8 meters (25 feet). This interface was
designed for computer communication at short distances. All computers have an RS-232
communications port. Refer to Section 3 for additional information.
RS-422 Network
RS-422 (EIA/TIA-422-B) is a standard communication interface that utilizes a differential balanced
transmission scheme that uses a typical maximum cable length of 1.2 km (approximately 4000 feet).
The main advantage to RS-422 over RS-232 is the longer cable length that is possible. A signal
converter is needed to convert the computer’s RS-232 to RS422. Refer to Section 3 for additional
information.
Modem Network
The modem is a standard communication interface that utilizes standard phone transmission lines. The
phone company assigns each phone line a number that the modem uses to communicate between
controller and display. Refer to Section 3 for additional information.
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 2,000 feet. A signal converter is needed to convert
the computers RS-232 signal to fiber optic signal; a minimum of two fibers is required.
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 length of 2000 feet. 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 ED13348 for the additional information.

Daktronics AF-3165 Galaxy displays are designed and manufactured for performance, reliability, easy
maintenance and long life. The pixels have a 34mm center-to-center spacing, and are lit using LEDs
(light emitting diodes). A light sensor on the front of the 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-3165-RRCCC-34-X
AF-3165 = Outdoor 34mm Louvered Galaxy Display
RR = Number of Rows High (8-48)
CCC = Number of Columns Long (Up to 144 Columns Standard)
34 = 34mm pixel to pixel spacing
X = LED Color (32,000 RGB)
