Figure 4-30: Wiring for Up/Down Counting
Note: If you need only one type of counting, connect C0A+ and C0A-
for Up Counting only; or connect C0B+ and C0B- for Down
Counting only.
Bi-direction Counting
For implementing Bi-direction Counting, you need to connect
C0B+/D+ and C0B-/D- to implement the control function for Up/Down
Counting. Up Counting : when the input signal is within logic level "1",
the counter value increases.
Figure4-31 : Wiring for Bi-direction Counting
Down Counting : when the input signal is within logic level "0",
the counter value decreases.
Note: If users select TTL mode and don't connect C0B+ C0B-,
the counter value will increase. If users select Isolated
mode and don't connect C0B+ C0B-, the counter value will
decrease.
