Interface Definition

Interface description

The following figure shows the interfaces of the PixelMax 4K Spectrometer. The optical fiber interface is the SMA905 interface, which is used to connect the sampling accessories such as the reflection probe, the transparent reflection bracket, and the liquid flow tank. The MicroUSB interface is used to connect a computer via a data cable. The 2.0MM-24P interface (24pin port) is used for secondary development of the spectrometer.
