TTL modeConnection of TTL encoders with or without zero pulseConnection encoder TTL mode with zero pulseConnection instructionsIn TTL mode the inverse inputs are not connected.When using an encoder without zero pulse C, the terminal points for the C track are not connected.Connection of TTL counters / pulse generators with or without zero pulseConnection counter / pulse generator TTL mode with zero pulseConnection instructionsIn TTL mode the inverse inputs are not connected.If a counter / pulse generator is connected, the B track determines the counting direction.Input B̅ is not connected.When using a counter / pulse generator without zero pulse C, the terminal points for the C track are not connected.
