LED (light emitting diode): Low energy, high intensity lighting units.
Pixel: Each circle on an LED block represents one pixel. Each pixel is made up of a
red and green LED which when both lit creates the amber color. For monochrome
displays, only a red LED is used in each pixel.
Display/Driver Module: The module shown in
Figure 3 is 16 pixels high by 32
pixels wide. Each is individually removable from the front of the sign. The LED
pixel blocks are mounted directly onto the module board. The driver is responsible
for the switching and intensity levels of the LEDs.

Power Supply: Converts AC line voltage from the load center to low DC voltage
for one or more module driver boards.
Galaxy: Daktronics trademarked name for LED monochrome or tri-colored matrix
signs.
Network: Consists of multiple signs connected to each other. Up to 240 Venus 1500
controlled displays can exist on one network.
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). A signal converter is required to convert the comuter’s
RS232 signal to RS422.
