2. Tap : View and select: I/O Units
3. Scroll down and selected: Qtrack - d377
4. Scroll down to c1position
5. Run the encoder in forward direction while
checking the value for C1Position.
If the number counts up:
• No action is required.
If the number counts down:
• the connection of the two encoder faces
(0° and 90°) must be interchanged.
