BeschreibungDescription

Die Erfindung betrifft eine Vorrichtung, einen Adapter, zum Anschluß von handelsüblichen Bildschirmen aus dem Personalcomputerbereich (e.B. IBM - Kompatible) an Personalcomputer der Firma Apple, mit deren Hilfe ein Betreiben dieser Monitore an diesen Computern ermöglicht wird.
Der an Computern der Firma Apple ("Macintosh" Baureihe) verwendete Monitorsteckverbinder entspricht nicht dem Industriestandard und die Anschlußbelegung des Bildschirmanschlusses ist herstellerspezifisch. Die Firma Apple Computer bietet zum Betreiben an ihren Computern der "Macintosh" Baureihe unterschiedliche Monitore an, die sich in der Größe des Bildschirms, der Anzahl der darstellbaren Bildpunkte, der Bildu/iederholfrequenz und der horizontalen Ablenkfrequenz unterscheiden.The invention relates to a device, an adapter, for connecting commercially available screens from the personal computer sector (e.g. IBM compatibles) to personal computers from Apple, with the help of which it is possible to operate these monitors on these computers.
The monitor connector used on Apple computers ("Macintosh" series) does not correspond to the industry standard and the pin assignment of the monitor connection is manufacturer-specific. Apple Computer offers different monitors for use with its "Macintosh" series computers, which differ in terms of the size of the screen, the number of pixels that can be displayed, the refresh rate and the horizontal deflection rate.

Daher sind in den Steckverbinder des Monitoranschlusses neben den üblichen zur Bildschirmansteuerung notwendigen Videosignalen weitere Kontakte, sog. "Sense Pins" (So , Si, S2 ) integriert. Diese werden im Steckverbinder des Monitoranschlußkabels beschaltet. Aus der Beschaltung erkennen Apple "Macintosh" Computer welcher Monitortyp angeschlossen ist und wählen dann eine den technischen Möglichkeiten des Monitors entsprechende Bildschirmansteuerung (Videomodus).Therefore, in addition to the usual video signals required to control the screen, additional contacts, so-called "sense pins" (So, Si, S2), are integrated into the connector of the monitor connection. These are wired in the connector of the monitor connection cable. From the wiring, Apple "Macintosh" computers recognize which monitor type is connected and then select a screen control (video mode) that corresponds to the technical capabilities of the monitor.

Problemproblem

Will man an einem Apple "Macintosh" Computer einen handelsüblichen Bildschirm betreiben, der nach seinen technischen Spezifikationen geeignet ist, einen oder mehrere Videomodi der Apple "Macintosh" Computer darzustellen, so steht man vor dem Problem, daß die Steckverbinder nicht übereinstimmen. Darüberhinaus muß dem Computer durch entsprechende Beschal-If you want to use a commercially available monitor on an Apple "Macintosh" computer, which, according to its technical specifications, is suitable for displaying one or more video modes of the Apple "Macintosh" computer, you are faced with the problem that the connectors do not match. In addition, the computer must be provided with appropriate wiring.

tung der "Sense Pins" mitgeteilt u/erden, welche Darstellungsart bzw. Auflösung gewählt u/erden soll, anderenfalls werden keine oder ungeeignete Videosignale ausgegeben. Betreibt man Monitore, die mehrere Auflösungen darstellen können und will man den Videomodus wechseln können, muß man die Beschaltung der "Sense Pins" ändern können.
Dies wird erfindungsgemäß dadurch gelöst, daß mit der Vorrichtung (Adapter / Adapterkabel) eine Anpassung der Steckverbinder und der Verdrahtung der Monitorsignale auf die weit verbreiteten Standards vorgenommen wird. Darüberhinaus wird durch eine einstellbare Beschaltung am Steckverbinder erreicht, daß sogenannte Mehrfrequenzmonitore durch Änderung der Beschaltung mit verschiedenen Auflösungen betrieben werden können. Mit der Vorrichtung können alle mit der eingeführten Kodierweise denkbaren Beschaltungen der "Sense Pins" eingestellt werden, auch solche, die bislang nicht genutzt werden.The connection of the "Sense Pins" must be used to indicate which display type or resolution should be selected, otherwise no or unsuitable video signals will be output. If you operate monitors that can display multiple resolutions and you want to be able to change the video mode, you must be able to change the connection of the "Sense Pins".
This is achieved according to the invention by using the device (adapter/adapter cable) to adapt the connectors and the wiring of the monitor signals to the widely used standards. In addition, adjustable wiring on the connector means that so-called multi-frequency monitors can be operated with different resolutions by changing the wiring. The device can be used to set all possible wirings of the "sense pins" with the introduced coding method, including those that have not been used to date.

Die Vorrichtung wird vorteilhaft so ausgebildet, daß die Einstellmöglichkeit für die Programmierung der "Sense Pins" leicht, nach Möglichkeit von außen, zugänglich ist.The device is advantageously designed so that the setting option for programming the "Sense Pins" is easily accessible, if possible from the outside.

Stand der TechnikState of the art

Die Anschlußbelegung der Steckverbinder für das Videosignal an Apple "Macintosh" Computern ist ebenso wie die Anschlußbelegung der Monitore des Industriestandards bekannt und den jeweiligen Handbüchern zu entnehmen. Die Bedeutung und Funktion der besonders genutzten Anschlußkontakte ("Sense Pins") im Steckverbinder ist veröffentlicht (CT, Magazin für Computertechnik, Heft 1, 1992, Seite 194, Heise Verlag Hannover). Bekannt sind Anschlußkabel für Monitore einzelner Hersteller, in denen die Kodierung für die Auflösung durch eine feste, nicht änderbare Verdrahtung vorgenommen ist. EineThe pin assignment of the connectors for the video signal on Apple "Macintosh" computers is known, as is the pin assignment of the monitors of the industry standard, and can be found in the respective manuals. The meaning and function of the specially used connection contacts ("sense pins") in the connector is published (CT, Magazin für Computertechnik, Issue 1, 1992, page 194, Heise Verlag Hannover). Connection cables for monitors from individual manufacturers are known in which the coding for the resolution is carried out by a fixed, non-changeable wiring. A

einfache Anpassung der Verdrahtung der Videosignale ohne Kodierung wurde bereits beschrieben (vgl. auch CT, Magazin für Computertechnik, Heft 12, 1989, Seite 87, Heise Verlag Hannover).Simple adaptation of the wiring of the video signals without coding has already been described (see also CT, Magazin für Computertechnik, Issue 12, 1989, page 87, Heise Verlag Hannover).

Vorrichtungen, im Sinne von Adaptern, mit deren Hilfe die Verdrahtung angepaßt u/ird und die Auflösungskodierung einstellbar ist, sind bisher nicht bekannt.Devices in the form of adapters with the help of which the wiring can be adapted and the resolution coding can be set are not yet known.

Die beiliegende Zeichnung zeigt das Prinzipschaltbild einer möglichen Kodierungsschaltung. Die Schalter können mechanisch oder elektronisch, im einfachsten Fall auch durch Drahtbrücken realisiert u/erden. An die Dioden u/erden keine besonderen Ansprüche gestellt, es eignet sich z.B. auch der Typ 1N4148. Auf eine Darstellung der Verdrahtung der Videosignale u/urde verzichtet, da es sich im Prinzip um eine funktioneile 1 : 1 Verdrahtung handelt.The attached drawing shows the basic circuit diagram of a possible coding circuit. The switches can be implemented mechanically or electronically, in the simplest case also by means of wire bridges. There are no special requirements for the diodes, for example the type 1N4148 is also suitable. A representation of the wiring of the video signals has been omitted, since in principle it is a functional 1:1 wiring.

Weiterbildung der ErfindungFurther development of the invention

Die Erfindung kann zweckmäßigerweise bei der Entwicklung von Neugeräten (Monitore) derart integriert u/erden, daß die entsprechende Beschaltung der "Sense Pins" vom Bedienfeld des Monitors aus eingestellt u/ird. Dies kann dadurch realisiert u/erden, daß die "Sense Signale" bis in den Monitor geführt u/erden und dort mechanisch oder elektronisch beschaltet werden, oder indem vom Monitor aus eine Vorrichtung angesteuert u/ird, die im Steckverbinder untergebracht ist, und dort die "Sense Pins" beschaltet. Die physikalische Einheit des Adapters entfällt dann, da die Funktionen des Adapters in die anderen Systemkomponenten integriert wurden.The invention can be conveniently integrated into the development of new devices (monitors) in such a way that the corresponding wiring of the "sense pins" is set from the control panel of the monitor. This can be achieved by routing the "sense signals" into the monitor and connecting them mechanically or electronically there, or by controlling a device from the monitor that is housed in the connector and connecting the "sense pins" there. The physical unit of the adapter is then omitted because the functions of the adapter have been integrated into the other system components.
