Jr2 Transmitter
If you are looking for a simple solution and don’t need iTTL/ETTL or High Speed Sync, then the Jr2 System is the perfect way to trigger your off-camera flashes and studio strobes.
The Transmitter simply attaches to your camera hot-shoe or via a cable through the PC Sync port. It provides incredibly simple controls that are easy to learn even for a beginner. Control 4 different groups of off camera lights, easily toggle your groups on and off, and save your settings to 4 different memory locations. The Jr2 transmitter can also control any PX Receivers you have when used with a Canon setup.
Lithium Batteries Recommended
Jr2 Receiver
The Jr2 Receiver is a great easy solution for triggering your off-camera flashes and studio strobes.
Simply attach the Jr2 Receiver directly to your speedlight style flash, or to your studio light via the included cables and you’re ready to go. You can control the power output of your Alien Bees, White Lightning or Zeus Strobes, as well as almost any E-TTL Canon or I-TTL Nikon compatible speedlight including the Nikon 700 and 900 series flashes.
The Jr2 Receiver provides stop accurate control for your lighting, and may be assigned to one of 4 different lighting groups for maximum creative freedom.

Jr2 Compatibility Guide
Jr2 Transmitter
The Jr2 Transmitter is compatible with any camera body with a standard hotshoe. It is also compatible with older Sony camera bodies using the FA-HS1AM Hotshoe Adapter. It may be alternately triggered using a PC Sync cord between the 1/8″ trigger jack on the Jr2 Transmitter and your camera body.
The Jr2 Transmitter can remote trigger a camera body with the appropriate remote shutter release cable. Please contact RadioPopper Support to determine the appropriate cable.
The Jr2 Transmitter will trigger the following RadioPopper devices: RP Nano Receiver, PX Receiver (when used on Canon compatible speedlights), JrX Receiver (Note, 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).
Jr2 Receiver
The Jr2 Receiver is compatible with most all studio strobes and handheld flashes with appropriate sync cable. Jr2 Receivers are shipped with 3.5mm cable, 2.5mm and 1/4 inch sync adapters.
The Jr2 Receiver can remotely control power levels of most E-TTL Canon or I-TTL Nikon compatible flashes, including the Nikon 700 and 900 series flashes.

I've always been an off-camera flash user. For a long time I relied on the systems built in IR system. Line-of-sight has always limited my creativity when it comes to light placement. Now I have full control without having to reach for my lights to manipulate settings.
