This test also may indicate that a PM 101 channel is
intermittent.
Module Test 8-3. In this sub-test, the Timing Option
Word Recognizer is set to trigger on the occurrence of a
hexadecimal 55 (specified by the Personality Module
ROM) and the State Machine is programmed with the
following test program:
1 IF TIM OPT WR=55 (WR1=TIM.OPT.WR)
AND WR2,3,4=DON'T CARE
1 THEN
1 GOTO 4
END
4 IF TIM OPT WR=55 (TIM.OPT.WR.=WR1)
AND WR2,3,4=DON'T CARE
4 THEN
4 TRIG MAIN AND TIMING
END
Also, the Timing Option Memory Address Counter is
set to "0". All Word Recognizers except the Timing Option
Word Recongizer are set to all "X" (don't care).
The Slow Clock Indicator is checked for the presence
of a clock. If none is detected, the following error is
reported:
3 FAIL 0FF60-1 ;
DETECTED
If the clock appears to be running, a byte is read from
the Personality Module ROM which specifies that the
Processor wait 2 ms for a trigger. Then a Store command
is sent. After waiting the specified 2 ms, the Acquisition
Memory Activity Monitor is examined to see if the Main
Section has triggered. If it has not, the following error
message is displayed:
3 FAIL 2E803-7 ;
TRIGGER
This error may be caused by a failure of the Personality
Module to generate a hexadecimal 55 on the Timing
Option pins of the Self Test Stimulus Circuitry.
If the trigger did occur, the Timing Option Memory
Address Counter is examined to determine the last data
location, and the trigger location is calculated. This value
is then compared to a value stored in the Personality
Module ROM. If the two are not complementary, the
following error message is displayed:
3 FAIL 3E03F-X
CORRECT
@
SLOW OR NO CLOCK
MAIN SECTION FAILED TO
; TRIGGER VALUE IN-
Maintenance and Troubleshooting-PM 101
This error may indicate an improper timing relationship
between the Clock signal from the PM 101 and the data
from the Self Test Stimulus Circuitry of the PM 101.
If the trigger test passes, the Timing Option Acquisition
Memory at address 2:F000-2:F0FF is checksummed and
the result compared with the expected value stored in the
Personality Module ROM. If the values are not the same,
the following error message is displayed:
3 F A I L 3 E 0 4 0 - X
2 : F000-2: F0FF
Where:"X" indicates the bit that didn't match.
This error may be caused by a failure of the Self Test
Stimulus Circuitry to consistently generate the correct
pattern or an intermittent Timing Option Probe.

Signature Tables-Boards A 1 and A2

All signatures in the following tables were taken with a
SONY/TEKTRONIX 308 Data Analyzer.
Configuration: Invalid signatures occur if the con­
figuration is not as specified. The PM 101 Self Test
Stimulus Circuitry provides stimulus for Test 7, the "PER.
MOD. - SYSTEM" test, of the DIAGNOSTIC MONITOR -
SIGNATURE EXERCISER routine. The probe must be
connected to the 7D02. The Self Test Stimulus is con­
nected normally except the Control Ii nes (06, 07, and 08)
on T18, T19, and T20 must be moved to the T2, T3, and T4
connections used by the Timing Option. Refer to Table
6-1.
