Default Nissin Di866 Master Flash control

I want to use the Nissin Di866 as a master flash to control other flashes, but without the 866 flashing as well. It is possible according to the manual, but it isn't working for me.

Any ideas?

I don't see how...

-> The Master flash controls the Slaves by modulating its flash output (i.e. high-speed series of On/Off of pulses which look just line one flash). In actuality it's a series of On then Off commands for each group of Slave, so in reality the Master flash pulses are actually 3 pairs series of On/Off for each group A, B, and C of flashes(which looks just like 1 flash to you)

You can insure that the Master flash do not contribute to the overall lighting by setting it's output to -3EV in TTL (or 1/128 in M mode) when the Di866 is programmed as the Commander, but the Master will have to fire in order to control the other wireless Slaves. This is the same principle whether its a Nikon, Canon, or Sony for that matter: http://www.friedmanarchives.com/flash.htm

If you don't want the Master to fire at all then get an Su-800 commander (or an ST-E2 in case of the Canon) which control the Slaves via IR (still light but invisible to human eye) instead, but this device costs as much as another flash!

BTW I couldn't find this link any more which explained very well, but I kept a copy of the graph: http://webcache.googleusercontent.co...www.google.com

I think I have it figured out now. The 866 flashes to communicate with the remote flash, but it doesn't flash during the exposure.

Thanks for the info you provided - it helped me decode what the manual was talking about.
