Hi,

re-opening this case

- Per previous question (sorry took time...was on vacation) here are our findings:

1. Until now on our products using the DLPR410AYVA we got the following readings:

DMD_VERSION = 101 or 111

DMD_TYPE = 000

2. on the boards we mounted the DLPR410BYVA we get

DMD_VERSION = 000

DMD_TYPE = 010

and thus, our SW indicates failures as it seeks the values of 5,7 for the version and 0 for the Type (i.e DLP9500UV)

Can you advise why? per the change notice the ID should not have changed

Moshe,

I believe per the update that DMD_VERSION is correct since there is only enough bit space for 0 - 7. Therefore, the version was wrapped around and the version reports binary 000. This is the version of the firmware.

However, I am concerned about the DMD_TYPE. Indeed for the 9500 I believe the DMD_TYPE should report 000. Further investigation is needed on this.

Moshe,

As a point of clarification, this is the same DMD that was previously being used so that the DMD_TYPE is the same. If I read your post correctly this is the DLP9500UV.

I am sending a private message regarding this since I know that some of the information is proprietary to your project.

Moshe,

Thank you for notifying me that adding version 0 as controller version solved this issue. I am closing the thread. THANKS again.
