Why does only one Falconeyes SS-350H strobe fire with my RF-DD4 trigger?

I have two Falconeyes SS-350H studio strobes and an RF-DD4 wireless flash trigger. Both strobes work, but when I press the test button or take a photo, only the strobe connected to the receiver fires. If I move the receiver to the other strobe, that one fires instead. Do I need additional hardware or a setting to make both lights flash together?

If you are using external radio triggers to trip your studio lights, you need one radio receiver unit for each light--so for your setup, you would need two RFDD-4 receiver units and one transmitter. The lights do not have any internal way of receiving a radio signal, so it's only the light that's connected to your single receiver unit that will flash.
However. The SS-350HD lights also have a built-in optical slave. The photo sensor is that bump on the top of the unit. It can sense when the other flash goes off. So, for the light that doesn't have a radio receiver attached to it, turn on the optical slave mode by pressing the "REMOTE" button on the back of the unit (it's labelled Photo Sensor Switch on page 2 of the manual).

Yes. With radio triggering, each strobe needs its own receiver unless the light has a built-in radio receiver. In your setup, the RF-DD4 receiver only triggers the strobe it is physically connected to, so only that one fires.
To fire both lights, you have two options:
- Use a second RF-DD4 receiver, one for each strobe.
- Use the SS-350H’s built-in optical slave on the second light. Connect the radio receiver to one strobe, then enable optical slave mode on the other by using the REMOTE / photo sensor switch. When the first strobe flashes, the second one should detect it and fire too.
Make sure the optical sensor on the second strobe can “see” the flash from the first light.
