There are four (4) network systems available: RS232, RS422, modem and fiber. Up to 240 displays
can exist on one network.
RS232 Network
RS232 (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 RS232
communications port. Refer to Section 3 for additional information.
RS422 Network
RS422 (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 RS422 over RS232 is the longer cable length that is possible. A
signal converter is needed to convert the computer’s RS232 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 RS232 signal to fiber optic signal; a minimum of two fibers is required.

Daktronics AF-3065 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). Each display section has minimum 9-inch character height. 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-3065-RRCCC-9-X
