Daktronics AB-1600-1.5,2.5 - Manual (Page 12)

1-6 Introduction
Module: Consists of four lampbanks mounted to the backs of two lens assemblies. A module, Figure
12, is eight pixels high by 16 pixels wide. One transformer can power two modules (256 lamps).
Modem: A standard communication method that utilizes standard phone transmission lines, and is an
option with the Venus 1500 System.
Pixel: Daktronics describes a pixel as being the point of light created by a single lamp behind a single
lens.
Power Termination Panel: Assembly in which incoming power
connects to the display. It mounts to the cabinet on the left end
(front view). Figure 13 shows the power termination panel
enclosure, both with the cover on the enclosure and with it
removed.
Quarter-Turn Fasteners: A type of latching mechanism found
on many Daktronics assembly enclosures. Using a Phillips
screwdriver, turn the fastener one-quarter-turn counter-clockwise
to release the latch and one-quarter-turn clockwise to secure the
latch.
RS/232: A standard PC communication type with a maximum
cable length of 25 feet (8 meters).
RS/422: A standard differential communication type with a maximum cable length of 4,000 feet (1.2
kilometers).
Serial Line Interface (SLI): The controller
board used in Venus 4600 display systems. The
serial line interface (also called a line receiver)
receives signal from the controller computer via
fiber optic cable and routes it to the display.
Figure 14 illustrates the metal enclosure that
houses the serial line interface, both with the
enclosure cover in place and with the enclosure
cover removed. The serial line interface board is
seen on the right.
