4.1.3 Input Signal Wiring
The device can receive external input signal via its I/O interface. This section introduces how to wire
the device to different types of external devices.
Note
●
Here we take LineIn0 as an example to introduce the input signal wiring.
●
Input signal wiring may differ with different types of external devices.
