Help with Yongnuo Flash Trigger

Classpro · 01-10-2015, 12:51 PM

I bought a Yongnuo YN560IV flash, and a Yongnuo RF-603C trigger, and cannot get the trigger mounted in the hot shoe of the camera to trigger the flash.

I set both the flash and the trigger to the same channel (and tried several different channels).
I mounted the trigger to the camera hot shoe and turned it on.
I set the flash to rx mode, Identified the trigger as an "Rf 60 3"
The right green light on the trigger is lit. The left light is not.
I have no idea what the "Gr" option does. I've set it to C, C1, C2, C3 - doesn't seem to make any difference.
Pressing the shutter does not trigger the flash.

Any help or suggestions appreciated.

What is your shutter speed?

I was investigating these triggers too and I found this video that says 603c version 1 does not work with Pentax but 603n ii and 603c ii (version 2) works with Pentax. I think I will buy 603n ii

Did you put the flash in wireless mode?

No need unless you're triggering optically.

You're correct version 1 doesn't work with Pentax.

The n and c II are the same triggers the difference is the shutter cable. Buy the C version to get the shutter cable that works with Pentax. They work fine on my K30.

Buy the Nikon CII version, the pins are not the same. Photos in my post from Dec.
