I just tested cycling through the cameras and the reverse OE camera is locked when engaged in R. You cannot cycle out of the rear OE camera. Once outside R you can cycle through them like I posted earlier.

 

Ok, thanks!

That is exactly what Chris from camera-source told me.

And yes, I'm the guy who want 2 backup camera. I want to try to emulate the F250/2017 trailer camera.

After discussing it with Chris (camera-source) thru email, here is what I'm gonna try; re-route the OEM camera from the bypass connector into the RCA dedicated for the backup camera and configure the module to use the RCA instead of the passthru...

That way It should be possible to have a video switch between the oem backup camera of the truck and the trailer backup camera into the little camera-source module. Thus having 2 switchable backup camera.

My kit has been ordered and is on its way...

PS: So far, I have only good things to say about the camera-source team. I exchange a few email with Chris and Tricia and both respond quite fast and seem very knowledgeable about what they sell. They are a pleasure to work with.

 

The idea was just to test if while in reverse the "reverse camera" was lockedout.

Which it seem to be.

I would of like to have been able to see the right side camera while in reverse to be able to see how close to a road curb I am while parallel parking...

I guess that it would have been a nice feature to have been able to see any camera any time and with the transmission in either forward or reverse.

But nothing is perfect!

 

How are you gonna reroute the OE camera from the main harness? Its not on a dedicated circuit (rear dynamic guidelines and rear sonar are shared, to name just two), so I seriously doubt what you're trying to do will work. I know putting one of the side cameras in the rear camera input in their module does not work. Again, OE takes precedence.

 

Hey,

Here is what the idea discussed with Chris (camera-source) is;





The dip switch of the module will need to be change to accomodate this new setup.

Still need to be tested... But that is the idea at present time.

 

You keep forgetting that you have the IPMB sitting in the middle.

 

Nope... We are putting the camera-source module right "before" the signal enters the APIM.

The IPMB is before that.

In my schematic, the IPMB would be somewhere on the "OEM hardness", so the connector that goes to the APIM, the one that the camera-source cable connect in-line with is receiving the video output of the IPMB...

This is the video signal that the camera source module intercept and replace with the front and side and rear; either thru a dedicated RCA jack or thru the cable that arrives from the IPMB...

 

And how are you processing a digital signal with three streams with their analog device? Do you know which wire(s) in the harness in your tailgate carry the video signal?

Their module already sits before the signal enters the apim but after it gets processed. Thats how they're able to get their analog cameras to work.

 

The camera source module is actually intercepting the video signal coming from pin 14/15 and replacing it with their own.

 

I'm working on this assumption here...

That the output of the IPMB is a pure NTSC signal. That the camera-source module has NTSC input, that the OEM backup signal that goes to the APIM and is intercepted by the camera-source module is NTSC and that the output of the camera-source module is NTSC...

If not, back to square one... And that would mean that the camera source module is a sort of NTSC to LVDS converter.

I guess the question is; what kind of video signal goes in to the APIM ?

So far we have theorized that the OEM camera are LVDS signal that reach the IPMB over a certain long distance cable. In the IPMB the video signal gets treated. But what comes out of the IPMB and goes to the APIM ? LVDS or NTSC ? If it's NTSC, It should work. If it's LVDS then it wont.

Your thoughts on this are most welcomed!

Thanks!
