RadioPopper Jr2 Transmitter Overview

The RadioPopper Jr2 Transmitter is a 16 channel, four group radio transmitter that operates on the 902-928 MHz, ISM band and is capable of adjusting the output of the flash using a separately purchased Jr2 receiver for Nikon i-TTL or Canon E-TTL/II flash units. Triggering and power control from distances of 300-1750' depending on conditions and environment is possible.

The transmitter's simplified, intuitive backlit display works on an easy to use button and dial design that indicates power levels, group selection, radio channel selection local or remote control and remaining battery power. The transmitter gets 20 hours of run time on two AAA batteries and weighs 1.7 oz. Triggering at sync speeds up to 1/500 sec is possible with cameras that have leaf shutters. The Jr2 Transmitter will also trigger a wide variety of RadioPopper receivers without power control. Please see the features section for a complete list.

Dial Operation - Selecting groups
Power levels are adjusted by simply rotating the adjustment dial. The adjustment is made to the highlighted group (or groups) with the frame around it. You can highlight all enabled groups at the same time. Adjustments are applied to all enabled groups and settings can be locked in
Toggle Groups On and Off
Enabling and disabling groups is easy. Just click the button for the desired group and it will toggle on and off. When toggling on, the power level will remain where it was when toggled off
Simple 9 Stop Max and Min Power Control
Power levels are set between 9.0 at maximum to 0.0 at minimum. The increments are based on an EV f/stop scale. One full increment change on the display of your Jr2 Transmitter is equal to one f/stop change on your camera.
Save Settings
The Jr2 Transmitter provides four memory locations for saving lighting setups. Each memory location can save a snapshot of the present settings, including which groups are enabled, which groups are highlighted for editing, and the power levels of each group
Recalling Saved Settings
This allows you to quickly restore previously saved settings and immediately resume shooting with your creative process uninterrupted. You may exit the recall mode at any time without altering the present settings by tapping the P button. The unit will resume normal shooting mode
Setting 1/3 Stop or 1/10 Stop Increments
Select between either 1/3 stop or 1/10 stop adjustments. When in 1/3 stop mode, each step of rotation of the dial will adjust the power level by 1/3 stop, and similarly in 1/10 stop increments when set to 1/10 setting
Setting EV vs % Mode
Each group many be independently set to a stop accurate EV scale, or a more approximated percentage % scale
Compatibility
The Jr2 Transmitter will trigger the following RadioPopper devices: RP Nano Receiver, PX Receiver (when used on Canon compatible speedlights), JrX Receiver (the group used for controlling JrX Receivers must be changed from EV mode to % mode. You will not have stop-accurate control of legacy JrX Receivers, though you will be able to approximate power level control from the % scale which approximates the dial position of legacy JrX Transmitter units. Remote power control of Nikon or Canon I-TTL/E-TTL/II flashes is possible with purchase of a dedicated receiver

I received and put the batteries included and also another ones but it doesn't work. It's supposed that i must click the P point but it also does not work. And you don't see the signal of battery inside,

Works great :)

Works great with the JrX series, since those are no longer made.

See any errors on this page?

question

I wanted to know does these transmitters work with the powerlight 1250 Dr if somebody can give me that information that will be nice
Asked by: Julio M.
This transmitter is not compatible with the Photogenic PowerLight 1250DR directly. You would need to add a receiver such as the RadioPopper Jr2 Receiver for Canon B&H # RAJR2RC in order to fire this monolight from the JR2 Transmitter.

question

How come there is a big difference in battery life specs between B&H and Radiopopper?B&H stated: Battery Life: Approx. 100 hours total power-on timeRadiopopper stated: Battery Life: Approx 20 Hours total power-on time
Asked by: Anonymous
It is a web error and the batteries last on the transmitter can last about 20 hours.

question

Regarding the question above. I was told by Radio Popper that I could connect this by wire for triggering while I have a flash in the hotshoe. Here is the response... Yes, you can indeed connect the Jr2 transmitter via the camera PC sync port, freeing up the hot shoe for an on-camera flash. All you need is a 3.5mm to PC sync cord. Can you confirm this?Thanks,Brian
Asked by: Anonymous
Yes the JR2 transmitter has a 3.5 port so from a cameras pc sync port you can attach this to the camera and not use the hotshoe.This is one cord of many that will work,Paramount PW-PC1 Sync Cord - Miniphone to Male PC - Straight - 12 B&H # PAPM1 Mfr # 17PWPC1http://bhpho.to/VA0PkD

question

Can this Jr2 transmitter trigger Jrx receiver?
Asked by: Evangeline D.
I think it can, but the folks at Radio Popper are super helpful I would call them to verify!

question

How do I select that I want this for canon camera? It says canon or Nikon optional but doesn't give the option to choose between the two. Does it somehow work for both? I added to cart and even then dos not give me the option to select canon or Nikon.
Asked by: Jacob
I have one that i use on a Canon, but i feel like the transmitter will work with either brand, it is the receiver that might be brand specific.

question

can I attach this to the PC cord?
Asked by: Anonymous
From the Radiipopper site. rpjr2. Attach the Jr2 Transmitter to any camera having a standard hot shoe connector. You may also attach the Jr2 Transmitter to the PC Sync or similar connector of your camera with the appropriate cable. In this case, connect the PC Sync port on the side of your camera to the 1/8 sync port on the side of the Jr2 Transmitter. The Jr2 Transmitter can be triggered by your camera's hot shoe or via the sync port on the side of the Jr2 Transmitter.
