control the balance of light among the groups or zones.

Please read your Canon manuals for more information
on Flash Ratio with E-TTL II and how to control groups from
the master flash.
1. Slide the MiniTT1 Transmitter onto the camera and
tighten the locking ring.
2. Slide a Canon Speedlite (set for <MASTER>) onto the
MiniTT1 and secure its locking shoe. Enable slave groups
in the master Speedlite per flash manual instructions.
3. Set the remote FlexTT5 radios to the desired slave
group (A, B, C) by using the Zone Switch on the side.
Note that PocketWizard Zones are used instead of
Canon slave groups.
4.
Slide the remote Speedlite onto a FlexTT5, tighten the
locking ring, and secure the FlexTT5. Repeat for each
remote Speedlite. The remote Speedlites should be set
to normal ETTL mode, not <MASTER> or <SLAVE>.
The slave group is set by the Zone Switch and not in the
remote flash. All remote E-TTL II flashes on the same Zone
will be treated as one zone of light.
5. Adjust ratios using the master Speedlite’s flash controls.
6. Trigger normally
You may use Canon’s Speedlite Transmitter, the ST-E2, instead
of a 580EX to control ratios.
