X666 XXXX Stop bit' error test for all SIS lines. All SIS line adr are tested to see if a stop bit check can be detected. The lines are used in pairs with one line made the rcv line. Thi'j is the line that should detect

the stop bit check. The rcv line is tested with LCDs of 0,2,4,5,6, and 7. The xmt line always is set up with LCD

=

7. A PAD char of X'03' is xmt, followed by the char X'02'. When the X'02' is being xmt, the pgm loops, checking xmt SDF bits 8 and 9 for 00; then the xmt SDF is set to X'180'. This should cause the xmt line to send extra bits of 0 and cause the rcv line to get a stop bit check. The sequence of operation in this rtn is:

a. Reset scanner.

b. Enable scanner.

c. Set display bit in the rcv line's ICW.

d. Set rcv line adr in rcv mode.

e. Set mode on the xmt line adr.

f. Set xmt line SDF = X'03' (2 bit times of PAD).

g. Setxmt line PDF

=

X'02'.

h. Set xmt PCF = 8.

i. Set scope sync 2.

j. Wait for L2 irpt on xmt PAD char completed.

k. Wait for xmt SDF bits 8-9 = O.

I. Set xmt SDF = X'180'.

m. Wait for rcv line adr char-svc L2 irpt.

n. Check that 'stop bit check' bit is on in rcv line's ICW.

o. Reset the 'stop bit check' bit.

p. Check that the bit is reset.

The above sequence is done for LCDs 0, 2, 3,4,6, and 7 on the rcv line adr; then the next SIS line is set up, and the whole test is run again. All lines use priority 3 and oscillator select O.

NOTES:

Note 1: The following reg are set up for all errors displayed in this rtn:

Reg X'11' = xmt line adr

Reg X'13' = rcv line adr; the adr that should detect the stop bit errors Reg X '16'

=

the LCD being tested on the rcv line (in byte 1, bits 0-3)

Note 2: On all error stops, the LCDs should be checked for LCD

=

F (feedback check). You can use the continue function (except for pretest errors during the set modes) to continue from the error stop to see if (1) only one line set, the whole LI B, or all SIS line sets in the scanner are failing, and (2) if the failure is for one LCD setting or all LCD settings. If only one line or one pair of lines is failing, suspect the line set card as being bad. If all lines on a LI B fail, check LI B cards and terminators. If all lines on a scanner fail or if only one LCD setting fails, suspect the scanner cards.

Refer to LIB card positions in the LIB section in Volume 3 (LiBs and line sets) because card locations vary according to LIB type. Other possible failures are that oscillator 0 is failing or oscillator select is not working.

X668 XXXX Pad flag test for SIS lines. Check that while the PAD flag (lCW bit 7) is on and the xmt PDF = X'FF', no char are rcv. Then turn the PAD flag off and check that char can be rcv. A pair of lines are used in each run of the test, with one line being the rcv line and the other the xmt line. All SIS lines are tested with LCD = 2, priority 3, and oscillator select O. A set mode is executed for both the rcv and the xmt lines. The rcv line is set in rcv mode, the xmt SDF is set to X'FF', the xmt PDF is set to X'05', the xmt PCF is set to X'8', and scope sync 2 is set. The rest of the test runs in the same sequence as that of the following error codes. As each test is finished, the next SIS line adr is used with the previous xmt line, and the test is run again. This continues until all installed SIS lines in the scanner under test are run in both xmt and rcv modes.

NOTES:

Note 1: The following reg are set up for error displays:

Reg X'11' = xmt line (ICW) adr as used to set ABAR.

Reg X'13' = rcv line (leW) adr as used to set ABAR.

Reg X'14' (for errors indicating L2 irpt is from wrong adr) = the line adr of the line that caused the L2 irpt.

Reg X'14' (for unexpected rcv data in the PDF or for errors that indicate ICW bits 0-7 are in error) contains ICW bits 0-15 from the rcv line ICW obtained by an input X'44'.

Reg X'16' = expected rcv lines lew bits 0-15 for rcv data PDF errors, or lew bits 0-7 error. The rcv ICW bits 8-15 are the PDF; byte 1 of both reg X'14' and reg X'16' should always be equal on all rcv data tests. ICW bits 0-7 are normally expected to = X'4n' in reg X'14', where n = OaF ('svc req' ,bit on, 'rev line signal detect' bit ignored, all other bits off). For telegraph LIBs, ICW bits 0-7 are not checked since an echo check may occur, setting modem check if no external current loop is present.

Note 2: For all error stops, the LCDs should be examined for a feedback check: LCD

=

X'F'. You can use the continue function (except for set mode pretest errors) to see if only this line adr, a pair of line adr, all lines in a LIB, or all lines in the scanner are failing. If only one line or a pair of lines is failing, suspect the line set card. If all lines in a LIB are failing, suspect the LIB bit clock control card or line terminators. If all lines in the scanner fail, suspect scanner cards or first oscillator card. See LIB card positions in the LIB section in Volume 3 (LIBs and line sets) because they vary according to LIB type.

X669 XXXX Scanner priority test. This rtn tests that the prioriLY between mUltiple scanners is correct. If L2 irpt are pending from multiple scanners at the same time, the 1st scanner should have the highest priority, the 2nd scanner the next priority, etc. In this test, the 1 st ICW of each installed scanner is set up to have a L2 irpt pending by setting ICW bit 41. Then the pgm checks that the scanners irpt in the correct sequence. The test is run using priority select 3 for all tested scanners. This test is not run if only one scanner is installed. If this test detects failures, you should make sure that all previous test rtn have run on all scanners before you use this rtn to try to isolate the problem.
