The DPS70 product is a display cluster that has a 7" touch screen, 4 analog gauges 
and 26 indicator lights. The product is provided with a Linux operating system. 

The product includes five NTSC/PAL D1 video inputs for display of vehicle 
cameras. Four of the video inputs can be simultaneously viewed on the display. 
The fifth input is recommended to be dedicated for the backup camera. 

The communication options to the cluster are USB host, USB device, RS232, 
10/100 Ethernet and 2 CAN buses.
