User Interface
The S8/T8 uses a remote control withRC5 protocol. The incoming signal is connected to
pin 67 of the UOC.
The "Top Control" keyboard, connected to UOC pin 80, can also control the set. Button
recognition is done via a voltage divider.
The front LED (6691) is connected to an output control line of the microprocessor (pin
5). It is activated to provide the user information about whether or not the set is working
correctly (e.g., responding to the remote control, normal operation (USA only) or fault
condition)
In- And Output Selection
For the control of the input and output selections, there are three lines:
•
STATUS1
This signal provides information to the microprocessor on whether a
video signal is available on the SCART1 AV input and output port (only for
Europe). This signal is not connected in NAFTA sets.
•
STATUS2
This signal provides information to the microprocessor on whether a
video signal is available on the SCART2 AV input and output port (only for
Europe). For sets with an SVHS input it provides the additional information if a
Y/C or CVBS source is present. The presence of an external Y/C source makes
this line ‘high’ while a CVBS source makes the line ‘low’.
•
SEL-MAIN-FRNT-RR
This is the source select control signal from the
microprocessor. This control line is under user control or can be activated by the
other two control lines.
