Getting to Know You What Is RadioPopper?
Who Is RadioPopper?
Welcome RadioPopper fans! We thank you for your
interest in the new X series ash control system.
The X system presently includes four new units.
The new units are packed full of features giving you
endless ways to combine units to form a control
system perfect for your own shooting style.
This Compatibility Guide is provided to summarize
and explain in detail the various ways the X series
units may be combined, as well as the features and
limitations of various combinations.
The RadioPopper PX and previous P1 model units provide a radio
signal bridge between any Master ash unit and one or more Slave
ash units.
Current model Canon, Nikon, and other brand ash units include
a built in capability to communicate wirelessly. Units such as the
580EX, and SB-800 may be placed on a user’s camera as a “Master”
device. A second ash unit may be placed nearby as an o-camera
wireless “Slave” device.
The on-camera Master sends instructions to the Slave by blinking
the ash tube to form coded signals. These signals are much faster
than your eye can see. This optical “Morse Code” represents control
instructions that command the remote slave to activate, at what
power level, and in what mode.
This is a tremendously powerful system with the one limitation
being that the remote Slave unit must be able to “see” the optical
Morse Code being sent from the Master ash. There must be a clear
“line of sight” between the units, which limits placement locations
for the remote Slave ash.
The PX Transmitter or P1 Transmitter sit on top of your Master ash
unit without making any electrical connection. As the Master ash
begins to blink it’s coded instructions, the PX and P1 Transmitter
units sense the electronics of the Master ash working. The PX / P1
then read these coded instructions and send them by radio signal
through walls and other obstructions to a PX or a P1 Receiver.
The Receiver contains an internal light source which is blinked at
high speed and matches the codes sent by the Master ash on-
camera.
Your Master and Slave ash operate normally, except the two
devices are no longer required to “see” each other. Long range
operation through walls and around corners is now possible.
RadioPopper began in early 2007 as a side project of
wedding photographer Kevin King. Kevin sought a
way to more reliably trigger wireless lighting while
maintaining the usefulness of ETTL, groups, ratios and
high speed sync.
The RadioPopper P1 entered production in January
2008 and began shipping in April 2008. As is evident
by the new X system, development on the system has
continued.
The small RadioPopper team is based in Phoenix
Arizona. All units are manufactured and tested in the
USA. Kevin lives with is wife, and two children.
