Need: Sekonic meter and/or wireless module datasheet

<p>Hello.<br /> I want to see if I can integrate this little transmitter <strong>INTO</strong> my Sekonic L-608:</p>

<p>http://www.ebay.com/itm/YONGNUO-RF-600TX-2-4GHz-Wireless-Remote-Trigger-for-YN560-III-Flash-Nikon-DSLR/162255546578<br /> If I completely disassemble this transmitter and strip it of anything I can chuck, including the battery, I might be able to fit the essentials into the tiny compartment in my L-608 that's reserved for the wireless module.<br /> Both, the Sekonic L-608 and the Yongnuo transmitter are powered by a 3V battery, so this is basically what gave me this idea. However, when I took my multi-meter to the wireless module connector, I was able to read 5 volts between some of the pins, so, I may have to use a resistor there but it's not a big a deal. That's about as much blind-testing as I'm willing to do on my L-608. Without knowing anything about the pin designation I'm not going to risk drawing any actual current from them.<br /> Then there's the "fire" set of pins that I have no idea are which. Without hooking up ALL the pins to a proper scope I couldn't tell which of them are actually used to transmit the "fire" signal. I might experiment with this but I rather I wouldn't. Especially that I don't know if the L-608 even makes any kind of output through that connector when the unit is not in the "wireless flash" mode. As far as I know, there's no way of getting into that mode, unless there's an actual wireless transmitter installed. I couldn't find anything in the Custom Settings but maybe I missed it.<br /> Maybe it's possible to shorten a pair of pins to fool the L-608 into thinking it has a wireless module installed.<br /> <br />So, what I need is a datasheet for either one of the light meters that are similar to my L-608, OR a datasheet for either one of the wireless modules. I just need to know what each of those pins is used for and I'll take it from there.</p>

<p>Can anyone help me with this? because I wasn't able to find anything on my own.<br /> Maybe there are actual markings on other models or some of the transmitters. On my L-608 there is nada...</p>

<p>Thanks!</p>

That's a ridiculous amount of

trouble just to get a

flashmeter to fire a flash.

The L-608 has a P-C coaxial

synch socket does it not? So

all that's needed is to

couple the radio trigger to

the meter's synch socket, and

that can be done with a

simple hotshoe to coax

adapter.

OK, the trigger won't be integrated into the meter, but it won't have taken hours of research and modification to get it to work either.

<p>Nothing ridiculous about it. If I knew how to get the meter into the Radio flash mode w/o the actual radio module it would be a one-hour job, given everything can fit into the compartment. The time spent on research and what not?.. Yeah,.. I guess, there's that too. It's inevitable when one wants to mod an electronic instrument without risking ruining it in the process.<br /> <br /> By now I have strong evidence (actual tests) that the L-608 does not make any kind of output via those pins, in the corded-flash mode.</p>

<p>Connecting the Yongnuo transmitter to the PC terminal? Like.. duh.. I already have it set up like that. I attached two small pieces of self-adhesive velcro: One to the battery compartment lid and the other to the transmitter, so I can attach and remove the transmitter at will. And I'll do you one better: To reduce bulk (and cost) I didn't actually use a hot-shoe adapter. I wired a short PC-cable directly to the transmitter. It works awesome, though it looks and feels gnarly. Plus, there's the extra battery (transmitter) that I have to worry about.</p>

<p>Anyway,<br /> Thanks for the advice.</p>

Apparently a microcontroller and appropriate

programming are needed to "fool" the sekonic meter into radio trigger mode.

<p>That's a bummer, man. I kinda had a feeling it wasn't that easy. Oh, well...<br>

Thanks and<br />End of discussion.</p>
