• Sign Mode
Positive Logic 5-V Differential Input:
Increments the count if pulse A is input when pulse B is at low level.
(Positive for frequency measurements.)
Decrements the count if pulse A is input when pulse B is at high level.
(Negative for frequency measurements.)
Negative Logic 5-V Differential Input:
Decrements the count if pulse A is input when pulse B is at high level.
(Positive for frequency measurements.)
Increments the count if pulse A is input when pulse B is at low level.
(Negative for frequency measurements.)
Positive Logic 12-V Pull-up Collector Input:
Decrements the count if pulse A is input when pulse B is at high level.
(Positive for frequency measurements.)
Increments the count if pulse A is input when pulse B is at low level.
(Negative for frequency measurements.)
