Error Messages and Self-Tests
The test hoods referred to above are as follows:
02620-60056 This is a male 50-pin test hood for use on
port #1.
02620-60062 This is a male RS-232C test hood for use on
port #2.
02645-60004 This is a female RS-232C test hood for use
on
an HP 13222 or 13242 data comm cable.
They are available as a 3-item set which can be ordered
either with the terminal (as option 981) or separately (as
the HP 13259A Data Comm Self-Test Connector Kit).
When the User Data Comm Test is completed, if no err::>r
occurred, the message "TEST PASSED" is displayed on the
line following the line where the cursor is currently posi-
tioned on the screen. If an error occurred, however, the
message "PORn ERROR n" or "PORT 2 ERROR n" (whichever is
appropriate) is displayed. The "n" in the error message is a
numeric error code which should be interpreted as follows:
Printer Test
o = (not used)
1 = (not used)
2
= baud rate too fast
3 = baud rate too slow
4
= control line error
5 = no characters came back
6 = wrong character came back
7 = framing error
8 = character overrun
The Printer Test, which is usable only if the optional in-
tegral printer is present, exercises all the features of the
integral printer to verify that it is functioning properly. To
initiate this test, press the following keys in the sequence
shown:
II
..
5ervice
key~
..
INT PRT
TEST
If the printer is functioning properly, it generates the test
pattern shown in figure 9-2.
Note
that if your terminal does NOT include the integral
printer, the" key label in the "service keys" set of
function
keys will be blank and pressing that key will have
no effect.
If an error condition occurs, either the message" Integral
printer error" or "PRINTER" is displayed. To clear the (
message,
press _. Note that the error condition may be
either of the following, in which case you could correct it
yourself:
1.
Out of paper.
2.
The metal latch (under the plastic printer lid) is not
pressed down securely.
There may also be a problem with the printer mechanism
itself. The Printer Test temporarily disables the terminal's
interrupt system. Data received over a data comm port
while the test is in progress may be lost.
Manufacturing Test
This test is used by HP manufacturing personnel during
the terminal "burn-in" process. The Manufacturing Test,
which is actually a set of tests that are run in a continuous
loop, does the following:
1.
Blanks the screen for 1/3 of the test then turns the
screen back on.
2. Tests
the video controller chip.
3. Verifies
the integrity of all firmware ROM chips.
4.
Non-destructively verifies the integrity of all RAM
chips.
5. Tests the keyboard/printer controller chip.
6. Tests
the integral printer (if present). Note that this
test does not, however, produce any printed output.
7. Verifies the integrity of the non-volatile RAM chip.
8.
Displays the test pattern shown in figure 9-1.
9. Verifies
the integrity of the character ROM chip(s)
that are present.
10. Tests both data comm ports. The data comm tests re-
quire a loopback test hood on both ports. They are as
described for the User Data Comm Test, above, except
that the baud rate mechanism is tested at all available
baud rates.
In addition, approximately every 15 minutes the printer
test produces printed output consisting of two rows of "X"s
followed by the current content of the display screen.
The screen is blanked during the first part of the
Manufacturing Test (about 6 seconds) and is turned back
on for the remainder of the test (13-25 seconds). You halt
the Manufacturing Test by doing a hard reset or soft reset.
