Pulse/Pulse Radio Button
Selecting this radio button puts your drive in Pulse/Pulse interpretation. In Pulse/Pulse mode, 
pulses received on the A channel are interpreted as positive changes to the Pulse Position 
Input, and pulses received on the B channel are interpreted as negative changes to the Pulse 
Position Input.
Pulse/Direction Radio Button
Selecting this radio button puts your drive in Pulse/Direction interpretation. In Pulse 
Direction mode, pulses are received on the A channel, and the direction is received on the B 
channel. If the B is high, pulses received on the A are interpreted as positive changes to the 
Pulse Position Input. If the B is low, pulses received on the A are interpreted as negative 
changes to the Pulse Position Input.
Pulse/Quadrature Radio Button
Selecting this radio button puts your drive in Pulse/Quadrature interpretation. If Pulse 
Quadrature is selected, a full quadrature encoder signal is used as the command. When B 
leads A encoder counts received are interpreted positive changes to the Pulse Position Input. 
When A leads B encoder counts received are interpreted as negative changes to the Pulse 
Position Input. All edges of A and B are counted, therefore one revolution of a 2048 line 
encoder will produce a 8192 count change on the Pulse Position Input.
