Hi Guys, I got the foxeer HS 1177 from RCH yesterday. And I was able to do the initial setup using the provided OSD cable and my LCD TV. It worked. Also i checked the same in my quanum V1 lcd it worked with OSD cable. But when i put it on to vtx and vrx there is no video. I tried with and without OSD, only difference is that when micro minim osd is connected it displayes telemtry but no video. With the same set up i had tried another soney 700TVL camera, it work no issues. With or without micro minm osd. this foxeer is NTSC cam, the vtx/vrx says they work for both ntsc/pal. So not sure what else to change. Is there anything to change in camera ?

also tried to do a factory defaults on CAM, tried another set of same vrx and 600mW vtx, no video still, and correction the CAM is PAL i confirmed from RCH Kumaran. Am exhausted of option to try.

Have you tried without micro minimosd connected?

Have you selected PAL in OSD config?

If you're getting OSD draw on vrx while missing the video info, your physical circuit is fine.

Yes I tried both.

When OSD connected: HS1177 - can see osd texts, but no video, another sony 700tvl cam - can see both video and osd text (This cam is NTSC).
When NO OSD : HS-1177 - snow white screen(when i trouch the cam its warm, so power is there) another sony 700vtl cam - video is there.

I have not changed the OSD to PAL, but in 1st place am not trying to get OSD work now. So direct connection without OSD should render just video correct ?

Check HS1177 on your LCD TV again

- Direct composite
- Through OSD

Post the result. Just to confirm there's nothing wrong with the HS1177.

- Video_out of cam directly to Video_in of LCD TV

- Video_out of cam to video_in of OSD, video_out of OSD to Video_in of LCD TV

What is the voltage rating of HS1177? Are you powering it from extra battery, BEC or VTX?

If you are using 5v then dont do it. Most of the cams are meant to work at 12v even though they say 5-22V. Most of the websites suggest not to use this cam with supply other than 12V. If you run a 4s or higher on your quad then i think you should try and get a mini buck converter to step down the voltage. If you dont, you will burn it up

I tried as you said,
HS1177 - Direct composite no video on TV. With OSD cable it has video.
Sony 700TVL - Direct composite YES VIDEO.

Yes i tried with 12v, and as am using 3s, no need for a step down ....

I don't know what this OSD cable is. Also when i type OSD, i mean micro minimosd board, not OSD cable. If you have access to soldering iron & appropriate connectors, you could've avoided this osd cable and made a single wire connecting cam to TV. It should display video in that case. Anyway, the HS1177 is working since you saw video somehow with it.

Your voltage is fine.
I suggest you keep aside that osd cable thing & do direct lines(simple wiring) to TV. It must display video in this case.
When u find video working, connect that video line to OSD board and check its output on TV.
If that too is fine, connect that OSD board video_out to vtx & check reception on vrx, assuming your channel selection & all other wiring are fine. Check PAL/NTSC option on osd config as well. Ensure proper earthing/filtering for all devices involved.

Yes actually did both as i mentioned in my previous reply, I tried just direct cam to TV AV jack, there is no video, just to make sure i did the connections correct, i tried another ccd cam directly it works, shows video.

And about the OSD cable i said its the one supplied with the cam to make cam settings. Have attached the pic.

Am curious, why we need to test via OSD(minim) in 1st place it should work with out OSD correct ? or HS1177 will work only with OSD ? Please let me know. I dont want OSD. Just a video will work for me.

Yes no necessity for OSD, but since you mentioned minimosd in OP, thought you had a thing for it.

This is an odd case. Almost like an impedance mismatch on the video line. Try loading cam video_out with a 75ohm carbon film resistor & see how it goes. I still prefer avoiding that OSD cable altogether for testing.

Regular ones are carbon film type. Use it. Use correct value.

i have some regular resistors from the arduino kit, not the carbon film as you mentioned i guess, will the regular ones work ?

Static/ snow in the goggles means the problem is on the VTx/ VRx side side. If the issue was with the camera, you would just see black. Which VTx are you using? If you are getting image in the goggles with a different camera, that must mean that your VTx and VRx are set to the correct frequency. Are you running the ground wire from the camera to the VTx?

If you see the above posts, we have eliminated each possibilities. At last we tried for a direct connection, yet dint wotk on a TV, where as other cameras worked a direct connection. Also i have checked in a working setup to disconnect the OSD out to tx, which gave a snow white screen. So i guess we cant say if its snow screen, its tx issue.

HS1177 - Direct composite no video on TV. With OSD cable it has video.


Is this still the case? The osd cable seems to have an inbuilt resistor.

Keep this same setup & feed this video directly to vtx. Keep common ground.

It should work since you were able to see OSD draw on vrx earlier. That means vtx did work properly. I'm assuming you've fixed it by now. From what info you shared, your cam & vtx are in working condition.

Did you open up the case and simply try out any continuity test between the cameras's solder joints and the cable, don't know why but it simply looks like a connector issue, for starters if you dont want to open up the case coz its new and may have to be replaced or something, try just powering it up and check if there's any voltage on the video line

That's a nice point,  yes I can't open it up. But one thing I observed s that it's getting warm when connected ..so + and ground works I guess ... may be video cable has connectivity issues .....

There is data coming in video pin of cam, otherwise there wouldn't be a usable signal at output of osd cable. Still, check readings on board video pin. The resistor inside osd cable is an assumption. If the osd cable is openable, have a look inside at the tracks.

@merin did you try the 75ohm resistor yet? You just need to lightly solder it btw yellow & black lines when it's in direct composite. Just to clear impedance issue as a cause.

You Are CORECT,  Till pins The connection are there else Won't work thru the OSD cable... what am thinking is the connector cable .... and am yet to try the resistor one. .. as of now these are the two possibilities 1. Connector or 2. Impedance. ...

From what i understand,

- You're using the same wiring harness for both cams. ie, connectors/cables are the same for both cams but only one cam works in direct case with this same harness.
- Your osd cable is in proper working condition.

Check continuity of all cables involved, connector to connector when plugged in. Separately check ohm range resistance btw video & ground wires of osd cable.

The section from hs1177 to the wiring harness is different  as it a different connector from other cam. So it's a possibility. Will try continuity. ..

Cable issues are mostly user fixable unless ofcourse it's broken or crooked beyond hope. I wouldn't invoke warranty for such, but it's your choice. I think there will be access windows to all 4 pins on the connector itself. See if you can tap into it & get a direct feed on tv from cam. That will confirm the fault. If you're up to it, solder directly into cam pins if not planning to move it around much.

Already did that and finally was able to see the video ...direct connection. .. and yes am not ready to open the case and solder Smiley ...
