Beschreibung:Description:

Die auf den Leitungen des SCSI Kabels (1) anliegenden Signale gelangen über die Logikeinheit (2), die Inverter und Latches enthält, zu den Leuchtdioden. Von den Invertern gelangen die Signale zu den Leuchtdioden (3) der Real-Time Anzeige (Echtzeit Anzeige). Von den Latches gelangen die Signale zu den Leuchtdioden (4) der gespeicherten Anzeige. Bei Echtzeit-Anzeige werden die Signale so angezeigt, wie sie an den Leitungen des SCSI Kabels (1) anliegen. Im Normalbetrieb eines PC's werden einige Leuchtdioden ständig flackern. Bei gespeicherter Anzeige werden die anliegenden Signale gespeichert und die Leuchtdioden leuchten konstant. Somit kann man die bereits aufgetretene Signale anhand der leuchtenden Leuchtdioden ablesen. Mittels eines Tasters (5) können die Leuchtdioden der gespeicherten Anzeige während des Betriebs gelöscht werden, um bei bestimmten Aktionen im PC-Betrieb die aufgetretenen Signale durch erneutes Aufleuchten der Leuchtdioden zu bestimmen.The signals present on the lines of the SCSI cable (1) reach the LEDs via the logic unit (2), which contains inverters and latches. From the inverters, the signals reach the LEDs (3) of the real-time display. From the latches, the signals reach the LEDs (4) of the stored display. With real-time display, the signals are displayed as they are present on the lines of the SCSI cable (1). During normal operation of a PC, some LEDs will flicker constantly. With a stored display, the signals present are stored and the LEDs light up constantly. This means that the signals that have already occurred can be read off using the LEDs that are lit. Using a button (5), the LEDs of the stored display can be deleted during operation in order to determine the signals that have occurred during certain actions in PC operation by the LEDs lighting up again.

Anwendung:Application:

An der SCSI Schnittstelle in einem Personal Computer können Festplatten, Wechselplatten, Bandlaufwerke, Scanner, Drucker und andere Geräte angeschlossen sein.Hard disks, removable disks, tape drives, scanners, printers and other devices can be connected to the SCSI interface in a personal computer.

Das Diagnosegerät überwacht ständig alle wichtigen Signalleitungen und zeigt die Signale an.The diagnostic device constantly monitors all important signal lines and displays the signals.

Standardmäßig wird das Gerät mit einem Anschluß zu der am häufigsten vorkommenden sogenannten Single-Ended Schnittstelle mit 50-poligem Flachbandkabel geliefert. Als Optionen stehen Adapter zu den externen SCSI-Anschlüssen sowie für die sogenannte Differential-SCSI-Schnittstelle zur Verfugung.As standard, the device is supplied with a connection to the most common so-called single-ended interface with a 50-pin ribbon cable. Adapters for the external SCSI connections and for the so-called differential SCSI interface are available as options.

Die Spannungsversorgung (+5V und Masse) gelangt über ein Kabel von dem internen Netzteil des Computers in das Diagnosegerät. Für die verschiedenen Anschlüsse der Hersteller stehen auch hier Adapter zur Verfugung.The power supply (+5V and ground) is fed into the diagnostic device via a cable from the internal power supply of the computer. Adapters are also available for the various manufacturers' connections.

Durch die Möglichkeit, verschiedene Adapter zu verwenden, ist dieses Gerät sowohl für sogenannte IBM-kompatible Personal Computer, wie auch für Macintosh Computer der Firma Apple, Workstations der verschiedenen Hersteller und fast allen anderen Computern geeignet, die mit der SCSI-Schnittstelle arbeiten.Thanks to the ability to use various adapters, this device is suitable for so-called IBM-compatible personal computers, as well as for Macintosh computers from Apple, workstations from various manufacturers and almost all other computers that work with the SCSI interface.
