I have AMT102 encoders .They output max 5mA current TTL signals and nothing counts when i rotate encoder. Do i need to give pull up resistors for inputs? Any shematics for input signals will be wellcome   |

| You shouldn't if it is TTL compatible, it depends on what you are driving in to? Try them on their own with a 2k PU resistor if necessary to test. Al.
