Edit: Option 2 "2(mildly easy) Use the same converter but rig a 3cell Lipo as the DC source instead of my car battery. " was used to solve this issue and is working well, Page 2 has the end result.
I bought my FPV gear and I'm currently studying for my HAM test to operate everything legally in the US. In the mean time I want to get my ground station set up since I will have all the parts long before my A/V Tx and Rx arrive from China.
I am going to use these 2 parts to make my ground station, I'm just not sure how I want to power it but I have these three options.
First, these are the parts I will be using:
Monitor: Acer 1716 s View attachment Acer_al1716.pdf <-- manual (I have more than one spare monitor but this one is the largest and has the best documentation)
RCA to VGA converter: http://www.ebay.com/itm/190596379150
The options to power these are ...
1(Easiest) Use a power inverter http://www.radioshack.com/product/index.jsp?productId=3812863 connected to my car and run the monitor and adapter off of my car battery.
2(mildly easy) Use the same converter but rig a 3cell Lipo as the DC source instead of my car battery.
I figure that going from DC to AC then back to DC will waste a lot of energy so I'd rather not do this. Which leads me to option 3.
3(Most efficient and most difficult) Bypass the AC to DC converter in the Monitor and run the display directly off of a 3cell Lipo, split the 12v power to a spare ESC and power the 5v adapter through the ESC's 3pin rx connector.
I know the monitor uses 12V DC because I took it apart and read the info on the AC converter board
The thing I need help with is figuring out where to connect my 3cell lipo to. The connection from the power board to the VGA controller board has 8 pins and I'm not sure what pins carry the power
I also am not sure how power gets to the display from the power board. There are 2 sets of 2 connectors (8 wires in all) from the power board to the display.
I am assuming that the display is using 12v and the LEDs are using 5v but I'm not sure what color wires go to what device. There are Red, Black, Green and White.
The good news: I found a manual with very detailed documentation including a wiring diagram! View attachment Acer_al1716.pdf
The bad news: I only understand half of the documentation!
Notes: Page 11 shows the connections of the modules within the device. Page 28 figure 7 is not accurate to my board model, there are no wires, but pins (see image included). Power board wiring diagram is on page 44.
So, my plea to the rest of the FT community who has been so friendly in the past, could you lend me a hand once more and help me figure out where to connect my 3cell lipo battery to power the display and vga control board without using the monitors AC converter board?
If this is successful (or an entertaining failure) I hope to produce an article on how to do this and will of course credit any who assist.
