OPERATING INSTRUCTIONS

Storing the General Purpose Personality Module

Keep the General Purpose Personality Module in a
clean area where the temperature remains between
° °
-62 C and 85 C. Humidity should not exceed 95%, non­
condensing. The PM 101 should not be taken above
50,000 feet.
Connecting the Personality Module to the Logic
Analyzer
�
Always be certain to turn off the mainframe
(logic analyzer) power before connecting
or disconnecting any Personality Module.
Turn off the mainframe power and insert the ribbon
cable connector labeled "PERSONALITY MODULE­
PM 100 SERIES" into the receptacle labeled "PER-
I
SONALITY MODULE-PM 100 SERIES" on the front of
the Logic Analyzer.

Connecting the PM 101 to the System-Under-Test

The leads on the other end of the Personality Module
are Data, Address, Control and Clock input lines, and one
System-Under Test Stop Not output line. The input lines
are buffered by the Personality Module for transmission to
the Logic Analyzer. The STOP output is a signal from the
Logic Analyzer to halt the System-Under-Test. The Data,
Address, and some of the Control Ii nes (C0-C5) are used
for Word Recognizer event definition. Control lines C4-
C9 may be used in acquisition strobe (state clock)
qualification.
The PM 101 has 24 Address lines, 16 Data lines, 10
Control lines, a Clock input and a Stop output. This allows
it to be used with a 7D02 having the Expansion Option
(Opt. 3, Field Opt. 03). The leads from the General Purpose
Personality Module are grouped into bunches of eight or
ten color-coded wires, each of which is fitted with a single
0.025 inch square connector. This allows connection to
almost any circuit. The wires are color-coded using the
standard resistor color-code scheme which is shown on
the Personality Module cover. Only the second digit of
two-digit numbers is used in the color coding. The heavy
black leads are Ground (GND). The grey lead next to the
end is the Clock (CLK) line. The remaining single red lead
is Stop System-Under-Test Not (/STOP S.U.T.). Refer to
the cover of the Personality Module.
@
NOTE
A"/" in front of a signal name or part of a signal name
indicates that the signal is active when low. E.g., R!W
implies
0 - Write
1 - Read
Because the PM 101 Personality Module buffers
signals with very fast rise times, it is import ant that
procedures be followed wnich minimize delay and prevent
cross-ta I k and other noise.
Always connect the input leads as closely as possible to
the signal source to minimize signal degradation.
Keep individual leads separated as much as possible
beyond the identification labels; closely bundled lines
increase cross-talk.
Connect the ground leads directly to the ground pin of
the signal driver wherever possible. Do not add any
additional lead length to the ground path. This probe will
only work correctly at high frequencies with systems
which have an effective system of grounds.
When used without the Expansion Option, only Ad­
dress lines 0-15 and Data lines 0-7 are functional.
Everything else about hook-up remains the same.
If the Expansion Option is present in the Logic
Analyzer, but the additional lines are unused, the displays
will show all "1"s in binary, or all "F''s in hex, wherever
there are lines without data. These can be inverted to
appear as all "O"s by inversion in the Format mode.
Control lines. Wheh connecting the PM 101 to a
system, the control lines are used primarily for two things:
qualification of data and qualification and synthesis of
clocks. Control lines C0 through C3 are stored and
displayed with each word. This makes them useful in the
acquisition of processor lines which are not on the
address or data busses, but which may be essential in
establishing the status of the system under test. If not
needed as control Ii nes, C0-C3 may also be used as
additional address or data lines, but they will still appear in
