This week, our team thought of doing something different from our usual postings – we decided to open up the NDSP-500 digital signage player and give you a brief look at what’s inside one of these players. The video is not of the greatest quality but it does give you an idea of the components inside a typical digital signage player and what connections are available. So here’s the video:
As you can clearly see, the unit is small… it’s smaller than half of an A4 paper. With this particular unit, there are several connectors at the front:
1. RS232 – this is usually to provide serial communications with another device. It can be used to control and manage an display screen – that’s if the screen supports RS232.
2. Secure compartment to store the SD card – it’s also a quick way to easily swap out the SD card without having to open up the box
At the back of the unit you will notice the following connectors:
1.Video output: the unit has these typical connections – S-Video Output/Composite Video and Audio, DVI, and VGA.
2. Video Input: Composite Video and Audio. With this particular unit you will be able to connect a video input source such as a DVD player, Foxtel, CCTV camera etc.
3. S/PDIF – for great audio quality
4. LAN port which support 10/100 Mbps
5. Two USB ports for connecting USB Storage
6. Power plug to connect the power supply. This power plug was different from other digital signage players we’ve seen in the past. It basically has a connector which allows you to twist and screw the power cable to the power plug.
Inside the player, all you will find is a circuit board, a frame for a small hard disk and several cables. As you can see from the video, you will not find a fan inside the player – this makes the unit very quiet when it’s turned on.
Would you like to see more videos? Let us know what you’ll like to see and we’ll try to get it done.
