Buy this camera: http://amzn.to/2uOolQ6
I bought an HS1177 Sony 600TVL FPV camera from Surveilzone, and I love the death out of the camera. However, for the longest time, I couldn’t figure out how to use the tuning cable, because it powers and delivers the signal to the screen all at the same time. As a result, I just simply couldn’t use it because I didn’t have the right connectors. This post is to help you modify the stock cable that comes with your HS1177 4 pin connector to make sure you are able to make the tuning settings that you need.
First up — this is the 4 pin connector I’m talking about. I’m used to this being a 3 pin + another 2pin somewhere for the OSD cable, however that’s not the way that this is set up:
The first thing you need to do is understand the cable. When you cut away the extra bit of shielding, you’ll find that there are actually 4 wires — positive power, negative power, signal, and signal negative. The power is obvious, and it can be 5-22v — you MAY want to just use 12v — there may actually be a problem with trying to power the adjuster cable with more volts. I don’t know for sure. Then the video signal has a positive and a ground.
The first step is to cut away the shielding and expose the wires on all cables. Then, grab your XT60 (or other power plug — whatever suits you best) and an old RCA connector. I used Female because that’s what I had around. The RCA end of the cable also has a shielding on it, so you’ll have to cut that away to expose it and have it look like this:
All laid out, your wiring diagram should look as follows:
Positive and negative power, signals connecting on the RCA cable, as well as ground connecting on the RCA cable.
Here is what my finished product looks like. I don’t have any good heat shrink for cables this small, so I just used electrical tape. Don’t hate me! DO solder the wires together underneath. If you have any questions about soldering or the like, please leave me a comment below and I’ll be happy to help.
Then, it’s a matter of plugging it into the camera, plugging the video signal into your goggles or screen, powering your goggles and the camera (with the newfound XT60) and you should have access to the OSD on the HS1177!
What settings should I use?
Oscar Liang made an awesome post on the proper settings, and I generally stick with his recommendation. You MAY want to turn off DWR, depending on when/where you’re flying, but for the most part you should be good! 🙂
Let me know if you have any questions! I’ll be happy to help!
