DIY ADC to DVI Adapter
Hello there,
I recently received 3 mint condition Apple Studio Displays from a friend. When I went to hook them up I realized that they used ADC connectors and not DVI. Well as I am sure many of you are aware of, I went to purchase a DVI to ADC Connector at the local apple store. Once told the price I gasped! 100 bucks for a simple connector, this cannot be. Well, I was not about to spend $200 on adapters I did not absolutely need. Luckily I still have a G4 Cube with an ADC connector built in, so one of the displays was put to good use. However, the other two displays collected dust over the past year. Well, I recently pulled them out and decided to do a little surgery and create my own adapter!
Firstly, I went right ahead and sliced on of the cords leading from one of the displays right in half. Upon examination I found 19 cables on the inside.
Second, I looked up the pinouts for the ADC connectors and got out my volt meter and put it on the lowest resistance setting. Painstakingly I stripped and tested each cable and wrote down each cable's color relation to each pin.(I made a .doc of it if anyone would like the information)
Thirdly, I cut a DVI cable in two and began the same process as stated in step two. With the DVI and ADC pinout information in hand I began the fun task of soldering each cable to the corresponding cable.
Fourthly, the next step was to procure a proper power supply. The display needs 25v DV to operate. I connected the power supply to the proper cables on the ADC cable. I didn't need USB connectivity so I didnt bother with the three USB connects inside the ADC cable(however, it would be very easy to connect a USB cable.)
The result is a working DVI-D to ADC adapter for under $30...
Note: The adapter will only work with a DVI-D connection. The ADC doesn't use any Analog signals, only TMDS video signals are used.
Message me if you would like the data sheet I created or need any help with a DIY project.
