Glossary  

 

Address: Identification number assigned to each sign in a network, set through the front 

panel interface. The central controller uses the address to differentiate between signs 

connected on the same network. Signs on the same network cannot have the same 

address.

Central Controller: 

Software system that can control displays remotely. This hardware 

device contains a message studio, schedule studio, a display manager, and other 

tools and options that are used to configure displays and networks for an Intelligent 

Transportation System.

Column:

 Vertical line of pixels.

Dynamic Message Sign (DMS): 

An electronic message display used on roadways to give 

travelers information about traffic conditions. Such displays may inform of events like 

traffic congestion, accidents, incidents, or roadwork zones.
Eyebolt (Lifteye):

 Heavy steel bolt with a loop attached to the top of the display cabinet 

for lifting.

Isolation Board: 

Interface between the power supply and the redundant power bus. It 

provides isolation between the redundant power bus and a failed power supply.

Light Emitting Diode (LED):

 Low-energy, high-intensity lighting units. Multiple, closely 

spaced LEDs form a pixel on the DMS display. 

Line: 

Horizontal row of modules. 

Matrix: 

Visible area on a display, measured in rows and columns of pixels.

Module:

 Component containing an array of LED pixels and pixel driver circuitry. Modules 

are placed next to each other to form the matrix of the display. 

NTCIP: 

National Transportation Communication for ITS Protocol.

Panelboard:

 Circuit breaker box that distributes incoming power to the internal display 

components. A single panel unit may include buses, automatic overcurrent devices, and 

switches for light, heat, and power.

Pixel: 

A group of LEDs that turn on and off to form the characters and graphics making 

up the message content.

Power Supply: 

Unit that converts incoming AC power to DC power as required by several 

components within the display. 

Power Supply Enclosure:

 2–4 power supplies that provide redundant power to the display 

modules. 

Relay: 

An electromechanical or semiconductor switch in which a current or voltage 

applied across one port or terminal controls electrical currents or voltages that appear 

across another terminal or terminals. 

Row: 

Horizontal line of pixels.

RS232: 

Standard PC communication type with a maximum cable length of 25' (7.62 m).

RS422: 

Standard differential communication type with a maximum cable length of 4,000' 

(1.2 km).
