Kistler DAQ(for up to 2 plates) & Esync2 integration

[kkl0511]

I want to connect a "Data Acquisition System (DAQ) for up to 2 force plates, 16 channels / 5691A"'s Trigger in and Optitrack esync2's External Sync Outputs. I connected it with a general BNC cable that I have, and it doesn't work. Has anyone successfully synchronized these two devices, or if anyone knows how to do so, please let me know.
