FlashPoint R2 Single Pin Transceiver (FPRRR2SPT)

[CuriosPic]

Hi all,

Has any one used FlashPoint R2 Single Pin Transceiver (FPRRR2SPT)?

I'm trying to use it as an off-camera slave and mount an old canon 430 EX speedlight on it for high-sync speed picture as a second fill light. My understanding the Transceiver should have trigger the flash timely, but it is not synced with the main light. I was shooting with ISO:100, F: 4, and S: 1/250. The 430EX was set in manual mode with 1/64 power.

Any input is appreciated.

Thanks!
