DIAGRAMFORKLARING
De enkelte diagramsider er foroven betegnet med et
bogstav f.eks. DIAGRAM A.
Komponenttryk og koordinatsystem
PCB-enhederne er forsynet med komponenttryk og
koordinatsystem pa bade print- og komponentside.
Ledningsforbindelser pa diagrammerne
Nogle af ledningsforbindelserne pa diagrammerne er
samlet i »bundter«. Hver enkelt af disse ledninger er
forsynet med en kode, der fortzller hvortil de gar.
Intern forbindelse pa en diagramside
Interne forbindelser pa en diagramside er angivet
med et tal, knakket pA ledningen viser i hvilken
retning den anden ende af ledningen findes (fig. 1).

Forbindelse til en anden diagramside
Forbindelser til en anden diagramside angives med
et tal, samt bogstav betegnelsen pa det diagram,
forbindelsen gar til (fig. 2).
Stedsymboler
Der anvendes to forskellige stelsymboler i diagram-
merne som vist.
= Stel der ikke er galvanisk adskilt fra
4 | lysnettet.
| = Stel
Signalveje og markering pa IC’erne
Signalvejene er vist pa diagrammerne ved hjelp af
kraftigere optrukne streger og pile. Der anvendes to
forskellige typer pile som vist.
—<—_ = Video, luminans, chrominans og audio
signalerne.
—<«— =DC.
Pilene der er vist pa benene af IC’erne, forteller om
det pAgzeldende ben er en ind- eller udgang.

KEY TO DIAGRAMS
Each individual diagram page is marked by a letter
at the top, e.g. DIAGRAM A.
Component print and co-ordinate system
The PCB units have component print and co-ordi-
nate system both on the print and on the component
sides.
Cable connections in the diagrams
Some of the cable connections in the diagrams are
assembled in »bundles«.
Each individual cable has its own code which tells
to where it leads.
Internal connection on a diagram page
Internal connections on a diagram page are indi-
cated by a number. The break on the cable shows in
what direction the other end of the cable is to be
found (fig. 1).

Connection to another diagram page
Connections to another diagram page are indicated
by a number together with the letter indication of
the diagram to which the connection leads (fig. 2).
Ground symbols
Two different ground symbols are used in the dia-
grams:
hl
lL = Ground
= Ground that is not galvanically separated
from the mains.
Signal paths and IC markings
The signal paths are shown in the diagrams by
mans of semibold lines and arrow heads. As shown,
two different types of arrow head are used:
——<—_ = Video, luminance, chrominance and
audio signals
—<«— -=DC.
The arrow heads shown at the IC pins tell if the pin
so indicated is an input or an output.
