Introduction
Thank you for your purchase of the RadioPopper PX wireless radio
system. We hope you’ll nd this system to be a valuable tool in your
creative lighting, giving you exibility and control never before
possible.
The RadioPopper PX system allows you to use the automatic and
high-speed sync functions built into your existing ash units without
concern of whether or not the master and slave units can“see” each
other. You now have the ability to place your lights wherever you
choose, then controlling the output power of each slave ash from the
camera body manually or automatically via your camera’s ETTL or iTTL
logic system. It’s also the world’s rst product to eectively provide
you high speed sync by radio. Enjoy.
Please read this short manual entirely before installing or operating
your RadioPopper PX wireless system. Proper installation is key to
correct operation.
If you have any troubles along the way, feel free to call or email.

How It Works
The RadioPopper PX system is beautifully simple. Quickly mount the
PX Transmitter to your Master ash or Commander Unit, a PX Receiver
to each slave ash. Your current master and slave wireless ash system
continues to function just as it always has, minus the line of sight
limitation.
The RadioPopper PX Transmitter “listens”to the light signal being
created inside the master ash unit or remote commander on your
camera’s hot shoe. The PX Transmitter sends this signal by radio where
it is read by the RadioPopper PX Receiver. The receiver then uses it’s
own internal light source to “reproduce” this light signal. The light is
emitted through a window on the back of the Receiver unit directly
into the infrared sensor on a slave ash, that slave ash responds to the
“reproduced” light signal just as it normally would had it seen the light
directly from the master ash.
Installation is easy. Just place the RadioPopper PX Transmitter on top
of your master ash or IR commander device using the included Velcro
pads. “Look Ma! No wires!”
On the receiving end, assemble the mounting bracket for your specic
slave ash. Then simply drop the PX Receiver into the mounting
bracket. No wires or adaptors and no complicated system to re-learn.
Now just power up and shoot. You’ve got remote control of your slave
ashes, full ETTL and iTTL support along with high speed sync all the
way to 1/8000, by radio.

WARNING!!! WARNING!!! WARNING!!!!
PLEASE read this section in detail for important warnings and notices.
USE ONLY THE SUPPLIED TRANSMITTER ANTENNA!
Using any antenna other than the one supplied for use with your PX Transmitter is a violation of Federal Law and may actually
cause damage to the radio inside the transmitter. This will also promptly void your warranty. Your PX Transmitter has been
carefully tuned to broadcast the maximum signal strength allowable by law. Altering the antenna characteristics is more
likely to“de-tune”or degrade performance than to improve it.
INSERT THE BATTERY IN THE CORRECT DIRECTION!
Inserting the batteries“backwards”could possibly damage the electronic components inside PXTransmitter and PX Receiver
units. The little“bump”on the AAA always points away from the spring. A graphic is provided at the base of the AAA battery
holder, as well as on the back side of the circuit board for reference. Further, you should observe for the Green Power LED
blinking a few times about one second after you insert the battery - indicating proper insertion.
DO NOT REMOVE OR TAMPER WITH THE CIRCUIT BOARD!
Some of the components inside your PX Transmitters and PX Receivers are especially susceptible to electrostatic shock (they’re
easily‘zapped’by static electricity) - just touching them could damage them. Your circuit board is grounded to the case - as
long as it’s not removed everything is safe. Breaking the glue seal and removing or tampering with your circuit board will
promptly void your warranty.
YOUR POPPERS CAN’T SWIM!! KEEP THEM DRY!!
The new splash-proof design of the PX goes a long way to keeping the wet stu out. However, they are *not*“waterproof”.
Don’t use them outside in the rain, to photograph objects under water, or in any other environment that may allow water to
enter the physical enclosure or battery area.
If you dunk them, it may be too late. Should you do manage to expose a RadioPopper to anything wet, remove the batteries
as quickly as possible and allow it 24 hours to dry. You may nd it has come back to life. Allowing anything wet inside the
case of your PXTransmitter or PX Receiver will promptly void the warranty.

Installation: RadioPopper PX Transmitter
1) Remove the battery compartment door on the top side of the unit.
2) Remove the cover and insert two (2) AAA size batteries into the battery holder. It is very important to follow the
polarity direction indicated on the inner sticker to ensure unit operation and avoid possible transmitter damage.
3) Replace the battery compartment door. Once batteries are inserted, the battery door should t snug.
4) Select the approximate mounting location on top of your Master Flash or IR Commander (supplied by your camera
manufacturer). Ensure this area is clean.
5) Attach theVelcro pieces together. Remove both backing sheets and ax the joined Velcro strips rst to the under
side center of the PX Transmitter unit. We recommend placing the“rough”hook side of the Velcro against the transmit-
ter, and the soft side of the Velcro against your ash or IR commander.
6) Hold the PXTransmitter with Velcro attached over the approximate mounting location on the intended Master ash
unit. Compare location to the picture in Fig 2.1 on page 13. Press down rmly and hold pressure for thirty seconds to
tightly bond the Velcro strip adhesive to both the Master ash unit and the under side of the PXTransmitter.
7) Do not pull the Velcro apart for several hours. The adhesive on the Velcro will set to full strength in 20 to 30 hours.
Care should be taken during this time to avoid upsetting the bond being formed between the Velcro and plastic to
ensure maximum long term adhesion.
8) Install the supplied antenna (the straight one) by screwing it onto the antenna connector on the face of the PX
Transmitter.
WARNING: Do not power up the PXTransmitter without the antenna installed - doing so could damage the output
stage of the radio transmitter.
WARNING: Use only the supplied antenna on the PX Transmitter. Using any other antenna is a violation of Federal
Law, and may actually cause damage to the output stage of the radio transmitter.
9) When mounting the PX Transmitter in the future by pressing theVelcro pads together - a greater bond may be
achieved between theVelcro hook and latch sides by pressing rmly, then applying a slight rotational force between
the Master ash unit and the PXTransmitter. This tends to“set”the Velcro pads together.

Installation: RadioPopper PX Receiver
NOTE:
It is extremely important that your PX Receiver be mounted in such a way that the
IR light sensor on your Slave ash unit cannot “see” the control signals being sent
by your Master ash unit. The Slave ash must only see the light control signals
being emitted by the light source behind the green circle window on your PX Re-
ceiver. The following steps will insure proper mounting and error free operation.
1) Remove battery compartment cover and insert batteries, just as you did with the PX Transmitter. Replace the
battery compartment cover.
2) Your included PX Receiver bracket will come disassembled in two separate pieces. You will notice that your
mount can be assembled to match various applications depending on which specic ash you are using. Locate the
appropriate notch on the cradle and slide it into place on the base mount. Ensure that the cradle has the support clips
facing outward as shown in Figure 1.1 on page 12.
3) Install the supplied antenna (the one with the 90 degree bend) by screwing it onto the antenna connector on the
face of the PX Receiver.
4) Insert the PX Receiver into the PX cradle so that the optical port is aligned with the hole.
5) Slide your your o-camera ash into the base of your assembled bracket. Remember to lock your ash into place.
Also, take care to align the hole in the foam ring with the light sensor on your slave ash. The foam ring should fully
touch your slave ash in every direction with no gaps. This will ensure your Slave ash unit will only“see”the signals
produced by the PX Receiver, and will not see the signals being sent directly from your Master ash if you are shooting
from a position signicantly close to your Slave ash unit(s).
NOTE: The large red transparent piece on the front of your ash is NOT the infrared sensor. In
fact this area has nothing to do with the wireless communication system - it is simply a focus
assist light. The correct sensor is a shiny dark black window on the outside of your slave ash unit.

Transmitter Mounting on Other Hardware
For mounting the PXTransmitter on other hardware such as the Canon ST-E2 and Nikon SU-800 IR Commanders,
the mounting is essentially the same. Mount the PXTransmitter to the very top of the Master device, about
centered with the magnetic pickup sensor facing forward and the antenna pointed upward.
For additional images of product mounting, please see the Support section of our website.
Canon ST-E2: We suggest mounting Velcro to the front side of the battery cover.
Nikon SU-800: Mount directly on the top edge, which is a bit rounded but with proper placement and pressure
on the Velcro pads, a good anchor should be achievable. You may also place the PXTransmitter on the front of
your SU-800 with the magnetic pickup sensor pointed upward. Velcro the unit to the SU-800 battery door.
Nikon “Pop-Up Flash”: Using the PX Transmitter Nikon Hot Shoe Pop-Up Flash Adapter (Sold Separately) sim-
ply slide it into the hot shoe. Next, clip your PXTransmitter into the top of the mount with the magnetic pickup
sensor facing forward. Ensure that your Commander mode is activated on your camera.

next menu each time the“P”button is pressed, and you will adjust the setting of the current menu by pressing the“X”
button.
IMPORTANT NOTE!!! When in Menu Mode, the radio will not be active for normal operation. If you attempt to
activate the system by taking a shot on your camera while in Menu Mode, the PXTransmitter will not send any radio
signals. Similarly, the PX Receiver will not receive or respond to any radio signals while in Menu Mode. Taking a shot
while in Menu Mode on the PXTransmitter will cause the menu to cycle o. All settings will be saved, and the radio
will automatically resume normal operation. The PX Receiver will NOT automatically exit the menu.
Indicator Lights - Your PXTransmitter and PX Receiver units provide various feedback and status information via the
Power LED (Green) and Link LED (Yellow).
Solid Green LED - Unit is powered on. This LED will blink momentarily during the activation of each shot.
Slow Blinking Green LED -This is an indication that your batteries are extremely low such that the PX unit can no
longer operate. The unit will power down. You may observe this auto power down at battery meter levels of 2 or less.
StrobingYellow LED - The unit strobes the yellow Link light after the radio sends or receives each successful shot. This
strobing is also an indication that the internal computer has received the expected status signals from the internal
radio circuitry. The unit is properly reset after power-up, after leaving the Menu Mode, or after a successful shot.
NOTE: The strobing yellow LED conrmation following each shot is DISABLED in Feedback Mode 2.
P1 Mode - The Link and Power LED lights function exactly as they would on RadioPopper P1 Transmitter and Receiver
units. Please refer to the section“P1 Clone Mode”on page 20 of this manual. Also refer to the RadioPopper P1 Owner’s

Operational Features
Battery Level Indicator
On both the PX Transmitter and PX Receiver, a two stage battery level indication system is provided. The battery level
may be checked by tapping the“X”button from normal operation. This enters the menu system, the rst screen of
which displays the current battery level. “b9”indicates fresh batteries. “b0”indicates dead batteries.
You may quickly exit the menu by once again tapping the“X”button. This makes for quick and easy battery level
checks by tapping the“X”button twice in a row from normal operation.
A second internal battery level check is performed when inserting new batteries, on powering up the unit, and at
regular intervals. This internal level check insures the power regulators have enough battery level remaining for
normal operation. Once the unit can no longer reliably maintain minimum power level, the Power LED will blink
slowly, then the unit will power down indicating dead batteries which must be changed. This automatic low power
down may occur at any battery level less than“b2”on the battery level indicator.
You may also use rechargeable batteries in your PX units. Rechargeable batteries provide a slightly lower voltage - this
is ne for operation, but you will note a fresh set of rechargeable batteries will not produce a battery level of 9 even
when fully charged. This is normal.
Group Power Levels (G1, G2, G3)
The Group Power Level setting allows you to manually and remotely control the power output level of various other
compatible devices. The RadioPopper JrX Receiver Studio provides the ability to manually adjust the power level of
Alien Bees and White Lightning brand studio units. Other future devices may also make use of this setting. Please
refer to the JrX Receiver owner’s manual for more details.
The three groups may be adjusted independently. To see what the current setting is without changing it, tap the“X”
button one time. To increment the level up, press and hold the“X”button. To reduce the level, press the“P”button
while holding the“X”button and the numbers will count down in reverse. It is recommended to use two hands or both
thumbs for this operation.
The level goes from 00 to 32 and does not automatically loop. A zero level“00”will *disable* that particular group
from activating at all. This makes it easy to remotely turn entire banks of studio lights on and o. Level 01 is
minimum, 32 is the maximum level of your device.
Each time the level ticks up or down, the radio transmitter sends a quick transmission with the new levels. All remote
controlled equipment on the current radio channel is instantly set with the new values. You can actually observe the
model lamp level of compatible studio lights rise and fall as the level for that particular group is ticked up or down.
RadioPopper PX Radio Wireless System
Page 17

Radio Channel Selection - (CH)
Your PX units provide 16 individual radio frequency channels. Multiplied by the four channels of your existing ash
system, this provides an eective 64 distinct operating channels. Increment the channel number by tapping the“X”
button. Channels go from 01 to 16, followed by“P1”or“P”, then back to 01. Setting Radio Channel“P1”invokes the P1
Clone mode. Please refer to the P1 section later in this manual for more information.
Set your PXTransmitter and all PX Receivers to the same radio channel.
VERY IMPORTANT: You must exit the menu system before your devices will operate normally.
Auto Radio Channel Selection - (Ac) - Receiver Only
Your PX Receiver provides a handy feature for selecting a Radio Channel. In most cases, all of the channels will perform
equally well. However, the PX units share a radio frequency band with other devices such as wireless microphones and
other control systems which may be present in your environment.
The Auto Radio Channel Selection feature will go through each radio channel and listen to the level of background
radio signals. The test loop is performed 50 times and the levels of each channel are averaged. The PX Receiver will
then lock in the channel with the lowest measured background radio signals.
This will ensure that any PX radio channel with any observable background radio signal will automatically be skipped
or rejected, thus a clear channel is always set. In most cases, all or most of the radio channels will be at the same level
of“quiet”, so the unit has a fairly random chance of picking any of the quiet channels. It is therefore normal to observe
somewhat random selection of channels. Also, as channel 1 is the default, the Ac feature will never select channel 1.
This does not indicate channel 1 as being any less“quiet”than others.
Invoke the Auto Radio Channel Selection by tapping the“X”button. The unit’s Link LED will blink for about one second
as the test is performed. The selected channel will be displayed and the unit will jump back to the previous CH menu,
displaying the current channel.
Hardware Mode - (H)
To provide maximum exibility and scalability, the PX units have being designed using completely separate internal
computer“programs”for handling each type of camera gear. These programs are tailored to best handle the dierent
“language”of control signals sent by various camera hardware. The current rmware provides full support for Canon
and Nikon hardware.
Tap the“X”button to cycle hardware modes. Set the default“C”for Canon hardware, and“n”for Nikon hardware.

Light Bright Level - (L)
The electronics, computer processor, and radio unit designed into the PX units are so ecient, that they actually draw
less power from your battery than a single LED light. It turns out that the Power LED is the most signicant draw of
battery power.
Battery life can be signicantly extended if the LED’s are dimmed. Additionally, you may nd yourself photographing
in very dark environments where bright indicator lights may be a distraction.
The indicator lights may therefore be adjusted to one of ve values. Tap the“X”button to cycle through the levels. The
lights will instantly adjust to the new level.
Feedback Mode - (F)
Your PX units provide several dierent types of user“feedback”following each shot. Tap the“X”button to cycle modes.
F1 - The default. After each shot you will see the Link LED strobe momentarily. On the PXTransmitter this indicates a
signal was observed from your Master ash device and sent by radio. On the PX Receiver, this indicates the radio has
observed and decoded a radio transmission.
F2 - No feedback is provided. The PX unit will quickly cycle following a radio transmission and ready for another shot.
This makes possible using the high speed shutter built into many camera systems. The PX units will easily keep up if
you are shooting 8 frames per second or higher while in this mode.
F3 - Diagnostic Mode. This mode is intended for testing and verication of proper unit operation. In this mode, after
each shot, the PX Transmitter will display a number representing the number of individual data bits observed from
your Master ash device. About a half second following, all PX Receivers will display the number of data bits decoded
from the radio signal and blinked out the light source inside the PX Receiver.
For proper operation, the PX Receiver(s) should always display the same F Mode number displayed by the PX
Transmitter. On each given shot, if these numbers are equal, it is an assurance the the PX units are functioning
correctly and with zero data errors. If it is observed these numbers are equal and your ash devices are not functioning
correctly, please double check the settings in your camera ashes, insure the correct Hardware mode is set in your PX
units, and double check the installation of the PX units on your Master and Slave ash devices.
Note it is normal that the computed numbers dier slightly from shot to shot as your ashes don’t always send the
same number of blinks. It is only important for purpose of this mode that the numbers match between PX Transmitter
and PX Receiver(s) on each individual shot.

Operating Instructions

Reset Defaults - (r E)
Your PX units may be completely reset to factory defaults using this mode. The reset will also invoke the factory
pre-test start sequence the next time your unit is powered on. To invoke the Reset to take place, press and hold the“X”
button. A time out will count backward for 5 seconds to zero. At zero the unit will blank the display, both LED lights
will strobe during the reset. The unit will then power down.
The reset is completely non destructive and may be performed at any time. During the reset, the PX unit will reset
Radio Channel 1, Canon Hardware Mode, Normal Feedback Mode, and will zero the Group Level settings.
The next time the unit is powered on, the factory pre-test will take place. During this test, the current unit rmware
version is displayed in the format, for example, “6 -”, then“01”. This would indicate rmware version 6-01.
