Cameras: two D455s
SDK and Viewer 2.40.0
PC New with Intel 7 CPU
Been unable to get cameras to operate in sync master/slave mode. I have tried various settings without success.
Based on the two white papers regarding synchronization, pin 5 is connected to pin 5 and pin 9 connected to pin 9. Ref: External Synchronization of Intel® RealSense™ Depth cameras being one of the two white papers. Used the jumper wire and 9-pin connector referenced in the white papers for testing.
Currently have in Viewer, under Stereo Module, Controls, Inter Cam Sync Mode is set to 1 for the Master and 2 for the Slave camera. Also under control, for the master, selected Output Trigger Enabled. Frame rates and size matched for the two cameras.
Streaming was turned on for RGB, Stereo, and IMU for both cameras. One camera is connected to a Thunderbolt 4 port and the other camera connected to a USB 3.2 port to prevent USB SCP overflow.
Writing to a fast external SSD via an USB 3.2 port. Have been successful in writing streams from two cameras to the SSD when not synchronized.
In Viewer, there is a Sync button next to the Record button. What is it for? How is it "undimmed" for usage? How is it used?
What is the correct Viewer operation sequence to have master/slave synchronization?
As a documentation note, in the two white papers for synchronization, the photo showing two cameras and the pin 5 and pin 9 connections with pin 9 to the right. In the subsequent wiring diagram, the orientation is flipped with pin 9 now on the left. This may initially confuse new users when making the camera connections.
