I am using a CST1 to trigger 3 RFT1's and a CyberSync CSR.

A shoot last week had the 3 RFT1's fail to trigger the flash units but the CSR worked fine.

I tried reseting the RFT1's with no luck, the red light did not flash after trying a test following the reset. This was on all three RFT1's.

Because all three are failing at once I assume the CST1 is at fault, but it is unusual that the CST1 will trigger the CSR but not the RFT1's.

Has anyone experienced this phenomena?

The RFT1 system and CyberSync system are two completely different systems which are not inter-operable. The CyberSyncs operate on an entirely different frequency and are encoded differently than RFT1. This is expected behavior.

While this is expected behavior, I get the feeling the lights with the RFT1's have fired in conjunction with the CyberSync triggered light, yes? If so, the most likely explanation is the slave eyes are still active for some reason on this lights, and were not positioned correctly to trigger this time. However, I could be incorrect about this and further investigation is needed.
