Learn what the Westcott FJ-XR Wireless Receiver does, how it expands your FJ trigger setup, and which strobes it works with for remote flash control.

Quick Answer

The FJ-XR Wireless Receiver lets you add extra strobes or flash units to an existing FJ wireless trigger setup by receiving signals from an FJ-X Trigger and passing them through a 3.5mm sync port.

Why You Might Need a Receiver Instead of a Second Trigger

If you already own an FJ-X3 or FJ-X2m trigger on your camera, adding the FJ-XR Receiver is often more affordable than buying a second trigger. It connects directly to a strobe’s sync port and listens for the same 2.4 GHz signal, so you can fire multiple lights without line-of-sight or extra cables.

The trade-off is that the receiver only receives signals — it cannot transmit. That means you cannot use it as a standalone trigger on a camera. For that role, you still need an FJ-X3 or FJ-X2m.

Compatibility Considerations

The FJ-XR works with the same 2.4 GHz frequency as the FJ-X Trigger series, but it requires a 3.5mm sync port on the strobe or flash unit. Not every studio light has that port, so check your strobe’s input before buying.

If your flash uses a different sync connector (such as a PC sync or a proprietary port), you may need an adapter. The receiver itself does not include adapters, so factor that into your setup planning.

Frequently Asked Questions

Does the FJ-XR work with any flash or strobe?: It works with any strobe or flash that has a 3.5mm sync port and can be triggered by a standard low-voltage signal. Lights with proprietary or high-voltage sync ports may require an adapter or may not be compatible. Check your strobe’s sync port type before purchasing.
Can I use the FJ-XR as a camera-mounted trigger?: No. The FJ-XR is a receiver only — it cannot transmit a signal. You need an FJ-X3 or FJ-X2m on your camera to send the trigger command. Keep one trigger on your camera; use receivers on remote lights.
How do I set up the FJ-XR with my existing FJ trigger?: Set both the trigger and the receiver to the same channel and group. Plug the receiver into the strobe’s sync port, turn on the strobe, and test fire from the trigger. The receiver will blink to confirm a successful connection. Match channel and group numbers on both devices for reliable firing.
Can I use multiple FJ-XR receivers at the same time?: Yes. You can pair multiple receivers with one trigger by assigning them to the same or different groups. Each receiver must be on the same channel as the trigger, but groups let you control lights independently. Use groups to control individual lights from one trigger.

Product Facts

FJ-XR Wireless Receiver: Compatible with FJ-X3 and FJ-X2m Wireless Radio Triggers; connects through the same 2.4 GHz frequency and plugs directly into the 3.5mm sync port of compatible strobes. This means you can add a non-FJ strobe to your wireless system as long as it has a standard 3.5mm sync port, expanding your lighting options without buying a full trigger set.
