Normally, you have to make a lot of connections to get the touchscreen monitor up and running.
VGA, USB and Audio are pretty straightforward, although they account for much of the cable mess already. Power is a bit more complicated as this needs to come from elsewhere. Having an automotive power system makes it even more complicated as there are very few monitors that can withstand automotive voltage surges, especially in 24V systems.
The White Bream DVI all-in-one system replaces all these connections with a single connector and cable. Some of the spare pins (second lane) on the DVI connection are used for USB and audio, and with some tricks, we have arranged for the power to be brought out as well.
Using a small feature module, the DVI connection can be ugraded to provide digital signalling in addition to the analog signals.
Another feature module allows for a second VGA output. This abuses the digital signal pairs and requires a special cable to connect the two displays. Only one of the displays can be powered from the DVI connection. The other display has to be connected in the ´legacy way´.
Because of the power connections on the DVI connector, it is very important to faster the thumbscrews on the mating connector! Even more important is to NEVER DISCONNECT THE VIDEO CABLE WHILE THE SYSTEM IS POWERED ! ! ! This gives a high risk of 12V being temporary applied to VGA or USB signals. Either interface will get irrepairable damage from such event. And this is not covered by warranty!
The all-in-one DVI works with most monitors that come with this cable:
