Nikon SB600 Power Control
I've just purchased two V6's and an RF60 to use with my Nikon D90 Camera and SB-600 flash. I have the SB-600 set to TTL and mounted on a V6 set to RX mode. The RXing V6 has been setup to use the Nikon SB600 profile. Try as I may, the power output of the Nikon flash doesn't change. I raise or lower the flash power setting on the TXing V6 and watch it change to match on the RXing V6. When the flash is fired (By taking a picture) the power level of the SB600 is not altered.
As a test I replaced the V6/Nikon SB-600 with the Cactus RF60 and adjusted power levels using the TXing V6. This time the output level of the flash changed.
I have reset the SB-600 to its default settings, checked the RXing V6 to ensure the flash is unlocked, the profile is set to the correct flash and the Channel and Group match. The TXing V6 is in manual mode, not TTL Pass Through. Still no luck. No matter what I try the power level on the SB-600 cannot be adjusted. It's always full. I feel I must be missing something with my configuration but cannot see what it is.
If I interchanged V6's, make the TXer the RXer and vice-versa than I see a difference when the flash and unit are turned on (Flash first then V6). The flash immediately fires its test shot then displays the symbols TTL BL FP in the display of the SB-600. With this combination the power is controllable
Why won't it work if I interchange V6's? I've compared the settings on both V6's. They appear to be the same. What steps should I take next?
FYI: Firmware on the V6's is 1.1.007
