5.2.5.13 Test 13 - Electronic Vertical Format Unit. Test 13 exercises the 14 electronic vertical format unit (EVFU) channels and the paper-slewing operation of LP300/LP600 printers. It causes lines of text (identifying the line number) to be printed by setting appropriate channel numbers for both slewing and vertical tabs. If the line number in the text corresponds to the actual line number of the hard-copy page, the EVFU is operating correctly.

5.2.5.14 Test 14 - Graphic Example Plot. Test 14 exercises the plot mode by producing a graphic representation of r*cos(theta) and r*sin(theta).

5.2.5.15 Test 15 - TI Logo Plot. Test 15 exercises the plot mode by producing a graphic repre-sentation of the TI logo.

5.3 KEYBOARD DEVICES: 820 KSR TERMINAL

The ST820 diagnostic task tests only the Model 820 Keyboard Send/Receive (KSR) Terminal devices that have the device/forms control (DFC) option. For more information about the DFC, refer to the Mode/990 Computer Mode/820 KSR Data Termina//nsta/lation and Operation manual.

5.3.1 Introduction

The 8T820 diagnostic is composed of 11 noninteractive tests and 1 interactive test. The tests pro-duce hard-copy results that you must evaluate. Examples of the results of al112 tests are shown in Appendix E. The interactive keyboard test (Test 12) will not execute unless you are present at the target terminal to respond to the prompts. Interactive tests must be asked for specifically. Do not take the default prompts. Monitoring the control terminal during the 8T820 tests does not provide meaningful information about the test results. Table 5-7 lists the tests of the 8T820 diagnostic.

To begin the ST820 diagnostic, enter the name of the target 820 terminal in response to the ENTER DEVICE NAM E? prompt of the XD command verb, as follows:

ENTER DEVICE NAME? ALL

STxx

where:

ST identifies the terminal diagnostic task.

xx is the device number of the particular 820.to be tested.

5.3.2 Test Descriptions

The following paragraphs describe the ST820 diagnostic tests in detail. Tests 1 through 11 are noninteractive. Test 12 is interactive and requires your presence at the target terminal.

5.3.2.1 Test 1 - Form Length and Feed. Test 1 checks for accuracy in form length and feed.

The forms in the printer must be properly aligned to the top of the form before Test 1 begins. Test 1 performs the following:

1. The form length is set to 30 lines, followed by a form feed.

2. The message THIS LINE IS AT THE CENTER OF THE FORM is printed.

3. The form length is set to 34 lines, followed by a form feed.

4. The message THIS LINE ISATTHETOPOFTHE FORM is printed.

5. The form length is set to 64 lines, followed by a form feed.

6. The message THIS LINE IS AT THE BOTTOM OF THE FORM is printed.

7. The form length is set to 66 lines, followed by a form feed.

8. The message TH IS LIN E IS AT TH E TOP OF TH E FORM is printed.

Check the positions of the printed messages ensure they are correct.

5.3.2.2 Test 2 - Character Set. Test 2 prints all of the characters in the 820 KSR character set in a block format similar to that shown in Figure 5-1 of the LP810 test descriptions.

The block letters represent the dot-matrix structure of the 820 KSR printed output. The dot-matrix structure is shown in the Model 990 Computer Model 820 KSR Data Terminal Installation and Operation manual. Compare the dot-matrix structure of the Test 2 output with that shown in the manual.

5.3.2.3 Test 3 - Ripple Pattern. Test 3 prints 94 lines of a ripple pattern consisting of all avail-able nongraphic characters, similar to Figure 5-1 of the LP810 diagnostic. Since each character appears in each print position at least once, you can examine the output for problems such as characters not printing in certain positions. The width of the ripple pattern depends on the paper width you specified in the XD command verb.

5.3.2.4 Test 4 - Buffer Length. To determine the maximum buffer length, Test 4 uses the paper width you specified in the XD command verb. The test prints the character string PRINTER*BUFFER*TEST, beginning with only the first two characters. Each successive line increases by two characters until the maximum buffer length is reached. Then, the test reverses and prints from the maximum buffer length back to the first two characters.

5.3.2.5 Test 5 - Carriage Return. Test 5 prints a sentence with every other character missing, followed by a carriage return to the same line. Then the same sentence is printed again with the opposite characters missing, followed by another carriage return. The full sentence THIS LINE IS PRINTED IN TWO PASSES is the result.

5.3.2.6 Test 6 - Tab to Line. Test 6 prints the following message:

THIS TEXT SHOULD BE AT LINE x This message prints on the following lines:

2, 3, 5, 9, 17, 33, 49, 57, 61, 63, 64

The variable x is the line number where the message is printed. For example, the first line printed by the test is aa follows:

THIS TEXT SHOULD BE AT LINE 2

When the forms are properly aligned in the ST820, the line numbers should be correct.

5.3.2.7 Test 7 - Set and Test Vertical Tabs. Test 7 sets the vertical tab stops as follows:

2, 3, 5, 9, 17,··33, 49, 57, 61, 63, 64

The test causes the printer to tab to each of these stops. After each tab stop, the following mes-sage is printed:

THIS TEXT SHOULD BE AT LINE x

The variable x is the tab stop number where the message is printed. For example, the test tabs to vertical tab stop 2, and prints the following message:

THIS TEXT SHOULD BE AT LINE 2

5.3.2.8 Test 8 - Tab to Address. Test 8 prints lines of reference numbers that identify the hori-zontal columns of the paper. The test sets addresses and prints an up arrow (t) at each address.

The test prints the following message:

ARROWS SHOULD BE IN FOLLOWING COLUMNS:

The test prints a list of the addresses below this message. You must verify that the arrows are in the correct columns.

5.3.2.9 Test 9 - Set and Test Horizontal Tabs. Test 9 prints lines of reference numbers that identify the columns of the paper. The test sets horizontal tab stops and prints an up arrow at each tab stop. It then prints the following message:

ARROWS SHOULD BE IN FOLLOWING COLUMNS:

The test prints a list of the tab stops below this message. You must verify that the arrows are in the correct columns.

5.3.2.10 Test 10 - Lines and Characters per Inch. Test 10 prints the following:

1. 61ines of 10 characters at 61pi and 10 cpi 2. 6 lines of 5 characters at 6 Ipi and 5 cpi 3. 6 lines of 17 characters at 61pi and 16.5 cpi 4. 6 lines of B characters at 6 Ipi and B.25 cpi

5. 31ines of 10 characters at 31pi and 10 cpi 6. 3 lines of 5 characters at 3 Ipi and 5 cpi 7. 31ines of 17 characters at 31pi and 16.5 cpi B. 3 lines of B characters at 3 Ipi and B.25 cpi 9. Blines of 10 characters at Blpi and 10 cpi 10. B lines of 5 characters at B Ipi and 5 cpi 11. Blines of 17 characters at Blpi and 16.5 cpi 12. Blines of B characters at Blpi and B.25 cpi 13. 4 lines of 10 characters at 41pi and 10 cpi 14. 4 lines of 5 characters at 4 Ipi and 5 cpi 15. 4 lines of 17 characters at 41pi and 16.5 cpi 16. 4 lines of B characters at 4 Ipi and B.25 cpi

The message BLOCK IS x CHRS/INCH AND n LlNESIINCH is printed before each output group.

For example, 6 lines of 10 characters printed at 61pi and 10 cpi appear as a square after the follow-ing message:

BLOCK IS 10 CHRS/INCH AND 6 LINES/INCH

You must verify that the output is approximately one inch square to determine that it is correct.

5.3.2.11 Test 11 - 8ell. Test 11 sounds the terminal alarm for three seconds and prints the fol-lowing message:

PRINTER BELL SHOULD SOUND FOR 3 SECONDS

5.3.2.12 Test 12 - Interactive Keyboard. Test 12 is an interactive test and uses the test inter-val timer. You must go to the target terminal and enter the information requested by the screen instructions. The test compares the character read from the keyboard (the entered value) to the character requested by the test (the expected value). When the entered and expected values do not match, an error condition is recognized. The error is noted at the target terminal, and an error message is written to the diagnostic history file.

Test 12 has five categories with several parts for each category. The five categories of Test 12 are as follows:
