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 1500 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,
ED-13932,
for the additional information.
Ethernet Network
Note:
The use of a quick connect cable or interconnect wiring between display
controllers will not allow separate control of the second display if the input
signal was Ethernet. Only separately wired primary displays are allowed when
controlled by an Ethernet signal.
1.
The Ethernet network that uses fiber optic cable is a standard
communication method transmitting light (signal) through a glass fiber.
When used with the media converter the fiber optic cable has a maximum
length of 2000 meters (approximately 1.2 miles). One media converter is
needed to convert the Ethernet signal from the hub or switch to fiber optic
signal and then a second media converter is located in the display that
converts the fiber signal back to Ethernet. A minimum of two fibers is
required. Refer to
Section 3
for additional information.
2.
The Ethernet network that uses copper cable is a standard communication
interface that utilizes a local area network (LAN). Utilizing Cat-5/Cat-5E
cable, this transmission scheme has a typical maximum cable length of 100
meters (approximately 330 feet) from an Ethernet hub or switch. The cable
will connect to a network hub and then to the Ethernet surge card in the
display.

Section 3
for more information.

Refer to Appendix A
Daktronics designs and manufactures AF-3197 Galaxy
®
displays for performance,
reliability, easy maintenance, and long life. The pixels have an 89mm
center-to-center spacing and LEDs (light emitting diodes). Each display section has a
minimum of 24-inch character height. A light sensor on the front of the first display
is used for automatic dimming of the LEDs based on the ambient light levels.
Refer to
