Yongnuo RF-602C Triggers

...I am unable to get my RF-602/C's to fire from my K-01...I looked at some of the other threads and it appears that Pentax will indeed fire the RF-602's... so, will they work with a K-01 and a K-30 or am I doing something wrong here ??? thanx

602C triggers don't have the same pin layout as the pentax hotshoe. If you want it to work, you need to use the 602N

Neither one will allow you to sync at 1/180 without some modification, try lowering your shutter speed.

Mine work the other way. The 602N with the same pin layout seems to get confused on my k100d and will sometimes mess up (I have not done the capacitor modification on my 602N). The 602C with the different pin layout works fine (up to the 1/160th sync speed). If I cover all but the center pin on the 602N with tape, there's no problem.


Have you tested the triggers independently of the camera with the 'test fire' button to see if they can trigger the flash? Installed fresh batteries? Lower shutter speed as suggested?

...aahhh ! the plot thickens...let me try some of your suggestions as it will be a few days until the 602 N's arrive, I will try the C's with a lower sync speed, etc., etc...thank you

...ok, the RF-602 N (Nikon) arrived today...it worked on the K-01 right out of the box, only gotcha was that the wake up (green led on the tx ) was active and flickering all the time...so, I placed a piece of tape inside the K-01 hot shoe covering the front contact (the contact is singular not either of the rear pair) and the flickering went away...so did the the green wake up capability, but when triggered the red led fired and so did the YN-560iii... BTW, the 560iii is the new Yongnuo manual flash that has the built in RF-602/603 receiver...sweet...a word of caution, apparently the RF-603 will not work in this scenario as the data transmitted by the 603 is different than the 602...as usual, your mileage may vary, your configuration may act differently...but mine works...I will continue testing over the next few days...but so far, all is well

...I spotted the 560iii on ebay a few weeks ago...its claim to fame over the ii was a built in rf-602/603 receive capability...I tried the 603's/K-01 but that combo did not work for ME, but the 602/K-01 did...sweet...plus I think the 560iii is a very good manual flash with a menu system that can be operated without the owners manual...again, your mileage may vary, but I am more than pleased with this combo...I'll continue testing and report any different findings

...just finished about 50 test shots firing the K-01 with the RF-602N and triggering three YN-560iii simultaneously...not a single mis-fire on any of the three flashes...perfect-o ! ...also by pushing the main trigger button on the TX half way down, the wake up signal is sent to the flash...even more sweet I am more than pleased

...ok, ran a quick 602N test with the Olympus OMD EM5...the oly hot shoe does not have the front contact as the k-01 does...so no need to cover any contacts with tape or whatever...again the green LED did not function to provide a wake up call to the YN-560 but it did trigger the flash correctly...the flash can be awoken by pressing the main trigger button on the 602 TX half way, if you desire... ...if not just shoot

...one other bit of info, apparently, others also noticed the yn-560iii with the RF602/603 RX capability as the 560 was in dire backorder for a few months...that backlog now seems reduced, so I am guessing demand was quite high

just found out that version N1, N2 and N3 refering to the type of bundled cables, nothing to do with the trigger unit
