The 9000A-010 Demo/Trainer is an 80286-based product that functions as a video terminal. When the 9100 key

37、board and monitor are connected, the operator can type characters from the keyboard to the screen. Built-in tests demonstrate RUNUUT, breakpoint, and other UUT code-dependent functions of the 9100 series and the 80286 pod. Faults introduced from a set of fault switches can be detected using various

38、9100 series tests. FEATURES1-2. Demo/Trainer features mentioned below are shown in Figure 1. 1.RS-232-C Connector 2.Video Connector 3.On (1) Off (0) switch 4.Power Connector: Accepts a standard three-prong power cord for 100, 120, 220, or 240V ac power. 5.Fuse: 100 or 120V ac uses 1.0A SLO BLO (110/

39、120); 220 or 240V ac uses 0.5A SLO BLO (220/240). See Line Fuse Replacement. 6.Line Voltage Selector Card: Card orientation in the slot determines line voltage compatibility. See Line Voltage Selection. 7.Fault Switches: Six switch banks (SW1 through SW6) of eight segments each. For normal operation

40、, all SW1 segments must be closed and all SW2 through SW6 segments must be set to OPEN. In any different configuration, each switch segment introduces a fault in the circuit. 8.Functional Test Switches: Four momentary push buttons connected to the Peripheral Interface Adapter. These switches control

41、 the function tests. 9.Status LEDs: The upper LED shows the number of the self-test in process. The lower LED shows either a cycling indication when code is running or a flashing “F” when a fault has been detected. 收音机爱好者资料库 Ra d i o Fa n s .CN LINE FUSE/VOLTAGE 2 10. Keyboard Connector 11.

Use RUN for normal operation, or use TEST when the pod is connected. 13. Pod Test Connector 14. Power Indicator LED LINE FUSE REPLACEMENT1-3. The line fuse is located in the

43、combined line cord receptacle/fuse holder located to the right of the power switch. 1.Push the power switch to off (0), and disconnect the power cord at the Demo/Trainer. 2.Slide the plastic fuse cover (labeled FUSE PULL) to the left. 3.Pull the lever over to raise the fuse out of the holder. Fuse i

44、nstallation requires following the previous three steps in reverse. Make sure the proper fuse is installed: For 100 or 120V ac, use 1.0A SLO BLO (110/120) For 220 or 240V ac, use 0.5A SLO BLO (220/240) LINE VOLTAGE SELECTION1-4. The Demo/Trainer can be operated with 100, 120, 220, or 240V ac 10% (25

45、0V ac maximum) at 50 or 60 Hz 5%. Any one of the four line voltages can be selected without disassembling the instrument. Line voltage is determined by the position of the voltage selection card (see Figure 1). The card is recessed in the fuse holder assembly. With the fuse removed, the “100”, “120”

46、, “220”, or “240” printed on the card can be viewed through a window in the fuse holder. A different voltage setting can be selected by changing card orientation in the slot. Use the following procedure to change the voltage setting: 1.Set the power switch to off (0), and disconnect the power cord a

47、t the Demo/Trainer. 2.Slide the fuse cover to the left, and remove the fuse. 3.Using needlenose pliers, grip the upper card edge and pull straight out. If this action does not dislodge the card easily, use the pliers first to lever the card up from the side. 4.Rotate the card so that only the desire

48、d voltage setting will be visible in the fuse holder window. 5.In order, insert the card, replace the fuse, and connect the line power cord. 收音机爱好者资料库 Ra d i o Fa n s .CN 3 FEATURES Figure 1. Features 收音机爱好者资料库 Ra d i o Fa n s .CN SETUP 4 SETUP1-5. The Demo/Trainer can be exercised independently (us

49、ing a keyboard and monitor) or in conjunction with a 9100A and 80286 Pod. Use with the 80286 Pod1-6. Use the following sequence when running the Demo/Trainer with the 9100 A and 80286 Pod: 1.With the Demo/Trainer power off (0), connect the Pod cable to J5 (labeled 13 in Figure 1). 2.Ensure that S5 (labeled 12 in Figure 1) is set to TEST. CAUTION With Pod operation, power must not be applied to the Demo/Trainer before it is applied to the connected 9100 and 80286 Pod. The Pod is protected through its energized protection circuitry. 3.Apply power to the 9100. 4.Now apply power to th
