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.
