Glossary
Controller:
A system that can remotely control displays. This system contains a message
studio, a schedule studio, a display manager, and other tools and options that configure
displays and networks.
Column:
Vertical line of pixels.
Controller Board:
Controls data for the entire display.
Display Address:
Identification number assigned to each display in a network. It is set
using the front panel interface. The controller uses the address to differentiate between
displays connected on the same network. Displays on the same network cannot have
the same address.
Display Configuration:
A display’s model number, address, etc. This information
automatically displays when operating the display.
Ethernet:
A local area network (LAN) protocol using a bus topology. The Ethernet network
card uses the TCP/IP interface to communicate with the server via the LAN.
Ethernet Surge Card:
An inline device that filters the Ethernet data line. It suppresses
surges to a safe voltage to protect the display controller’s Ethernet input.
Face Panel:
A latching, hinged door that hinges downward. The modules mount to the
face panel.
Fiber Optics:
Technology that uses light energy to transmit signal to displays via hair-thin
optical fibers.
LED (Light Emitting Diode):
Low-energy, high-intensity lighting units. LED displays offer high
resolution for distinct text. A cluster of LEDs form a pixel on the display.
Matrix:
Area on a display that plays content, measured in rows and columns of pixels.
Module:
A unit of the display that contains LEDs, a display board, and a driver board.
Modules are placed next to each other to form the matrix of the display. One driver
board is located on the back of each module.
Network:
Multiple displays connected to each other. Up to 240 Venus
®
1500-controlled
displays can exist on one network.
PCB:
Printed Circuit Board.
Pixel:
An LED that powers on and off to form character and graphic content.
Power Supply:
Components used inside a display that convert incoming alternating
current (AC) power to direct current (DC) power, as required by several components
within the display.
Row:
Horizontal line of pixels.
RS232:
Standard PC communication type with a maximum cable length of 25 feet (7.62
meters).
RS422:
Standard differential communication type with a maximum cable length of 4,000
feet (1.2 kilometers).
RX LED:
An LED on the signal converter that indicates the display is sending data back to
the signal converter.
