Is there any idea of how to link several SB 28 flashes in a wired setup from a Nikon X00 DSLR, except using Nikons own 3 pole+ gnd "100usd" cables. PC-sync do not work as i want. Some kind of CAT cable would be great.

I have a SC-17 shat i can take the signal from.

Also DIY solutions are welcomed.

Why are you wanting to go wired ? Have you tried comtrig T320 you can link them with cables.Though they work fine with sb 28 s wireless.

I like the dependability of wired sync systems like TRLcam's flash box. Check with Jeff to see if he still has some available. There is a how-to available from http://www.emmanuelrondeau.com/gallery- ... rap-ebook/. After having used Camtraptions remote trigger and receivers with the D-cell alteration, I may shift totally to wireless. They last for weeks in real winter cold temps and are quite reliable.

The current 2 day uptime is troublesome in my setup with Youngnuo RF603II triggers. Those works otherwise well and i actually will add a connector for external power source. I have read somewhere that the sender keeps up about 300h and the always listening receivers around 50h

I just want to have an alternative hard wired way to trigger the flashes in some places that are hard to access or are remote.
Or in my case, unpleasant due to abnormal wolf activity that makes it not so fun to move in some areas. Nothing has happened yet but this wolf pack of 6-8 is not at all afraid of humans.

I use the wiring in the Emmanuel Rondeau book too.

I had bad luck doing this DIY, soldering hotshoe adapters to 3-wire cables. I'm actually pretty decent at soldering, but the hotshoe pins can be weird and overtime I found my rigs stopped working consistently -- I went this route for a year or so. I then switched to Ethernet cables and hotshoe adapters with RJ 45 adapters or whatever you call them, whether that was the TRLcam box for Canon, or that Pixel or Phottix or whatever adapter for Nikon. The TRLcam box works better because hooking three cables to an adapter on the hotshoe puts strain on it and makes it hard to position in your camera housing, especially with commercial ethernet cables that are often stiff. I just missed the backlight on a shot because of this, the strain caused it to not work, midway through set. Making your own cables with high quality 3-wire conduit could be the best route I think, but I have had the wake up pin connection stop working over time on a couple of mine, not sure what is up, but due to this I started just going with the commercial stuff.

There is something real nice about a hardwired connection and not having to worry about powering radio triggers or having them stop working, which they sometimes do. I really dig the Camtraptions unit, but I did have a tx unit stop working after a couple years. Not a big deal except when it's during a set and you miss a shot. That said, I've had rodents chew wires more frequently, just had one do my shutter cable for a trigger unit.

good luck

I find this thread most interesting.

I am doing camera trapping in Greenland and one of my main targets are muskoxen. They tend like scratching on anything sticking out so I fear they would get entangled in any wires - and hence destroy the set. I will therefore try using radio syncs for my planned camera trap using flash.

I have ordered a batch of Yongnuo RF-603 II and intend to modify them to use external C or D cells.

Does anyone have any power comparisons on the Yongnuo RF-603 II and the Camtraptions/Commlite ComTrig G430 triggers.

Best regards,
