4.1.4 Output Signal Wiring
The device can output signals to external devices via its I/O interface. This section introduces how
to wire the device to different types of external devices.
Note
●
Here we take LineOut0 as an example to introduce the input signal wiring.
●
Output signal wiring may differ with different types of external devices.
