multiple groups of flash units in a manual way.
▪ – – The flash units in the group do not fire.
"Double-dash" mode disables an entire group so that you
can concentrate on configuring the other group. Then
you can turn the disabled group back on and configure it
too. Or, you can just use one group of slaved Speedlights
(A or B) and disable the other.
Channel – This one channel controls all slaved flash units.
You must match the
flash unit. This is the channel on which communications flow
to all grouped, remote flashes. You have a choice of four
channel numbers, 1-4. This allows you to use your flash units
near another photographer who is also controlling groups,
without firing the other person's flash units accidentally. You
just each choose a different channel.
