Daisy Chaining YS-D1 & UFL-1: Any Ideas?

[Randallr]

I just upgraded to a Sea & Sea YS-D1 strobe to work off my Olympus XZ-1 camera in Olympus's OEM housing. I'm pleased to report that the pre-trip mirror test shows it firing and syncing in both DS-TTL II mode and Slave-TTL mode (and I think in manual, but I need to do more testing). I'm using fiber-optic cables to connect.

However, my hope had been to daisy-chain into the setup my UFL-1 strobe, so I could use both lights at the same time. I know that the UFL-1 strobe is firing, but the mirror test shows it's not syncing with the shutter and the other flash. Does anyone have any ideas of how I can get the strobes to sync?

Are you slaving your UFL-1 off the camera or the strobes? Olympus uses a multiple preflash. If you try to fire their strobe off the other strobe, the timing may be wrong. Try using only the UFL-1, then slaving the other strobes off it. Another method is to set the camera and strobe to slave, so you get only a single flash and use manual settings, not ttl. Make sure your strobe is set to the correct setting, either ttl or slave and all the strobes match what the camera is doing.
