BI-DIRECTIONAL COUNTING MODES
“B” serves as the direction control input. In the Times 1 Mode when “B” is at
a low level, a negative going transition at “A” will cause the counter to count
in the positive direction. When “B” is at a high level, a negative going
transition at “A” will cause the counter to count in the negative direction.
TABLE I illustrates the level settings of the Mode Select Inputs for the various
modes of Bi-Directional counting. The Times 2 Mode works like Times 1 Mode
except the counter changes on a positive going transition at “A”, as well as on
a negative going transition at “A”. There are also two Divide-By Modes which
prescale the display by 10 or by 100. This results in the capability of displaying
the 7th and 8th digit of the internal counter. (Along with Times 2, this gives an
equivalent -5 and -50 display.)
QUADRATURE COUNTING MODES
input “B” serves as the quadrature input. (Input “B” is a pulse train shifted 90
away from “A”.) The counter will count in a positive going direction when “A”
is a negative going signal and “B” is low. The counter will count in a negative
going direction when “A” is a positive going signal and “B” is low. All
transitions on “A” are ignored when “B” is high. These logic rules provide the
basis for anti-jitter operation which will prevent false counts from occurring,
due to back-lash, vibration, chatter, etc.
various modes of quadrature counting. The Times 2 Quadrature Mode works
the same as Times 1 when “B” is low. But when “B” is high, counts are no
longer ignored at “A”. Instead, the logic rules for “A” are complemented,
allowing both edges of “A” to be counted. This gives an effective doubling of
display count but more importantly, doubles the resolution of the input. The
Times 4 Mode extends this even further. Both “A” and “B” serve as count or
quadrature input. In one instance, “A” will be the count input and “B” will be
the quadrature input. In another instance, “B” will be the count input and “A”
will be the quadrature input. This will result in counts and resolution four (4)
times greater than in the Times 1 Mode. For counting rates on these modes,
refer to the specification sheet (X2, X4, -10, -100 give an equivalent divide-by
2.5, 5, 25, and 50).
For Bi-Directional counting, input “A” serves as the count input, while input
For Quadrature Times 1 counting, input “A” serves as the count input while

ANTI-COINCIDENCE SUMMING MODES
Inputs. These modes effectively separate count pulses which may simultaneously
occur at the two inputs. The unit then processes the count pulses into a string of
time-separated pulses so that the internal counter will not lose any counts. Both
inputs respond to the negative going transition in the Times 1 Mode.

Note: The maximum count rate for all Anti-Coincidence counting modes is 20
ANTI-COINCIDENCE ADD/SUBTRACT MODES
Input and “B” serves as the Subtract Input. This mode is identical to the Anti-
Coincidence Summing Mode with the exception that all counts appearing at
“B” will now subtract from the total counts. Both inputs respond to the negative
going transition in the Times 1 Mode.

DECIMAL POINT AND LEADING ZERO BLANKING
SELECTION
settings required for decimal point
selections, except for the last one
shown, have leading zero blanking.
As can be seen from the Table, the
zero immediately to the left of the
decimal point is turned on, while
digits to the left of that zero are
turned off.
For Anti-Coincidence Summing, input “A” and input “B” both serve as Add
