Herelink HDMI Input

HereLink
7

If someone is willing to send one to our team in Xiamen, I’m sure they would love to help figure it out. Unfortunately we don’t have all possibilities of cameras to try

Not sure we can do that with the Export restrictions on that camera.

Hi,
I have a camera with an analog video output. Do you know how I can plug it to the Herelink? It is impossible now with the two hdmi inputs.
Maybe by openning the Herelink I can solder the analog video wires at some places?

11

There is no place for an analogue video feed in HereLink.

You need to either get a hdmi camera, or get a analog to hdmi converter

Anyone happen to know if the FLIR DUO Pro R HDMI output is compatible with the Herelink system? According to FLIR the output is as follows: Digital Video Output: 1080p60, 1080p30, 720p60

Thanks,

Rich

Yes we use the FLIR DUO Pro with herelink on our machines. before the firmware update it worked with 1080p at 30fps. After the firmware update on the herelink it works with all 3. 720p 30, 720p 60 and 1080p 30.

Thank you!

Thanks! Out of curiosity, are you using PWM or MAVLINK for camera control?

16

I will also be wanting to use a flir vue pro with the herelink, if you end up getting this to work please let me know, also what are you using for HDMI out on the Flir?

17

Wn0x we use PWM, just 2 of the 3 outputs from the camera as with PX4 I’m limited with aux channels

Thanks Cameron!

I am able to get GPS data to the Duo Pro reliably via both Serial4 and Serial5, but can’t trigger the camera with the standard shutter commands.

Would love to find someone who is able to control the shutter, color pallette, picture mode and zoom etc. via Mavlink.

I havent managed to get Mavlink to work and would also be very interested on how to do this. Ardupilot gives me more Aux channels to use (I think i had 5 aux channels running at one stage. But we want PX4 and this seems more limited

20

just use ardupilot

John,
I was just going to test a few analog to HDMI converters with my Vue Pro. Though I didn’t get far into the test due to a herelink issue, I can confirm that this one was working, though testing was very brief before the link issue occurred. I will be updating this thread with adapters and cameras that function. I hope to contribute to a database of working cameras or at least provide feedback. Feel free to send me a message or reply if you have questions.

Is nice and compact.

Andrew,
You may want to look at the recent update I made to the thread I linked in my reply to John, I tried one that is a clone of yours, and a different one, which ended up being half the size. If volume is critical to your application, it might be worth looking in to.

All the best

Hi,
Does any one know which HDMI protocol or which HDMI chip the herelink is using?
We are actually designing a custom camera PCB which outputs HDMI but it seems to compatible.
Thanks,

Thanks MadeByMan, but the chip you mentionned is producing HDMI from MIPI protocols.
I’m looking for the chip which has HDMI as input (the one where the two HDMI are plugged in the air unit).
