The device is designed to display alphanumerical characters, raster graphics and vector graphics on the image from camera.  The OSD-50HD is produced as a PCB and dedicated for devices, where simultaneous observation of the image is required as well as the reading of data sent from the sensors placed in the device. Assuming OSD-50HD cooperation with such solutions as Arduino or Nucleo, we recommend using the PORT-22 converter in addition.

From the video signal the OSD-50HD operates as a loop-through device, equipped with signal input and output. The device control protocol can be found in the technical documentation.
