Analog Audio/Serial Input Connector
The Makito X4 Rugged analog audio/serial interface provides two (2) mono audio input signals and one mono audio output.
The audio input channels support 48-kHz sample rates with 16-bit PCM data. The audio input channels support up to Vrms (or 2.2 dBu) (single ended) inputs. The input impedance of the audio input channels is 33 kOhms.
The analog audio/serial interface also provides four (4) serial signals and one serial ground. The serial connector supports RS-232 and RS-422 operation.

Note
The System Reset button (RST# signal) provides two options:
If you press and hold the button for less than 4 seconds, the system resets and loads the last saved configuration. If no configuration was previously saved, the default settings prevail.
If you press and hold the button for more than 4 seconds, the module performs a complete factory reset. It clears all of the previously configured settings, including IP, streams and encoder configurations.
