Appendix D. Operational Patch Panel 1
The 100 position operational patch panel 1 contains the
Basic Counter Unit input and logical functions for counters
0-7. (An overall view of the patch panel is shown in Figure
26.)

Description
20 positions — provide the Basic Counter
Unit input signals from an external source.
Grid positions 1 and 2 furnish a two-way
distribution of the same signal to provide
flexibility.
3 positions — provide the logical input to
AND1. To perform combinatorial logic,
all inputs must be wired.
2 positions — provide the True function of
AND1.
1 position — provides the Not True function
of AND1.
3 positions — provide the logical input to
AND2. All positions must be wired.
2 positions — provide the True function of
AND2.
1 position — provides the Not True function
of AND2.
3 positions — provide the logical input to
AND3. All positions must be wired.
2 positions — provide the True function of
AND3.
1 position — provides the Not True function
of AN D3.
3 positions — provide the logical input to
OR1. Any True input position satisfies the
function.
2 positions — provide the True function of
O R].

Description
1 position — when wired, causes OR 1 to operate
as a latch and provides the reset function to OR1.
A True input allows the latch to remain set,
and a Not True input resets the latch.
4 positions— provide the logical inputs to
OR2. Any True input position satisfies the
function.
2 positions — provide the True function of
OR2.
1 position — provides the logical set to
LATCH 1. A True input sets the latch.
1 position — provides a reset function to
LATCH1. A Not True input allows the latch
to remain set and a True input resets the
latch.
2 positions — provide the True function of
LATCH 1.
2 positions — provide the Not True function
of LATCH 1.
1 position — provides the logical set to
LATCH2. A True input sets the latch.
1 position — provides a reset function to
LATCH2. A Not True input allows the latch
to remain set and a True input resets the latch.
2 positions — provide the True function of
LATCH2.
2 positions — provide the Not True function
of LATCH2.
4 positions — provide invert functions for in
coming or patch panel generated signals.
Each NOT block is a single-legged function.
8 positions — provide the output functions
for the four NOT blocks. Each NOT block
has two output hubs.
2 positions — provide a means of distributing
incoming or patch panel generated signals.
The logical definition of the signal remains
unchanged.
4 positions — provide the output functions
for the FANOUT hubs.
8 positions — provide the input signals to
each of the eight counters to count the num
ber of occurrences of an event.
8 positions — provide the input signals to
each of the eight counters to time the dura
tion of an event.
4 positions — provide a True level for AND1,
2, and 3 if all inputs are not wired to
logical functions. In this way unused AND
inputs are wired to satisfy the logical func
tion.
