I should preface with the fact that I have done this in the past, and a former co-worker just did 4 courtrooms like this.
We have 2 Group series 500 codecs in a combine/divide space. The customer wanted soft codec functionality with 4 cameras. So, we are using the QSC PTZ 12X72 cameras with their USB I/O bridges and DSP.
What am I missing here? Is there some API command we have to send to get this to work? Or do we have to connect the serial camera connection from the HDCI breakout to our control processor, and attempt to have it emulate an EEIV camera handshake? Is the codec looking for a slightly different timing?
Any help would be greatly appreciated.
Solved! Go to Solution.
I would like to add, that our engineer on-site has discovered that plugging the camera in directly will work just fine. It's when you go through the DM switch, and the scaling output cards, that we have the issues.
As a test:
Can the camera feed be routed through the matrix to any other display?
Can the camera feed be routed through the matrix and use the HDMI input on the GS?
With this additional detial more success may be had with Crestron support.
May want to include the firmware version for reference.
In the camera section of the Web UI, what does it show as being detected for the camera?
If you are not using the HDMI content input you can use that input and set the 'primary camera' to that input. That could also just be a good test.
Yes, the Camera can be routed just fine to any of the displays or as the content input.
Also, if the camera HDMI feed is plugged in directly to the HDCI DBA, it works fine.
The only thing I can come up with, is that all Crestron HDMI outputs are requiring the destination to have an EDID to ensure source to display compatibility, and there is evidentally no way to bypass this.
You could try something like this EDID minder in between the Crestron and the Codec
I had already anticipated that might solve it. So I overnighted some, and it turns out that no matter what you do the Crestron DM Chassis HDMI outputs will not pass anything unless they see an EDID on the destination device.
So, the Extron EDID managers/minders fixed the issue right out of the box.
We're having the same problem on one of our projects.
We tried the Extron EDID Minder with no luck.
Are you able to explain exactly what you did and how you did it to get the system working?
