<p>FlashQ claims it can handle up to 300V, but when I asked the manufacturer if I could use my 283 which I had measured at around 280V they said it still wasn't safe because my multi-meter doesn't show the peak voltages. So that's why I got the safesync.<br> <br />The Vivitar 2600 though is much lower, around 160V so I tried it with the FlashQ without the safe sync and that didn't work either.<br> <br />I think the above message trigger pulse length is the most logical culprit so far... but the manufacturer is taking their time answering my email.</p>

<p>Thanks for the tips... I'm still waiting to hear back from the FlashQ people on what they think is the issue before I abandoned the Vivitar 283 and get a new flash... Even if it doesn't work I'd like to know why it doesn't work.</p>

<p>I suspect you're right... I'm mildly in denial since I was hoping to use that flash instead of buying a new one. Fortunately I've only put in about $53 to "update" the Vivitar 283 (new battery holder, variable power adapter, and safe sync) and the latter two I can probably resell on ebay. Thank you for your feedback.</p>

<p>I've been putting together a two light (manual flashes) portable setup and one of the flashes I'm hoping to use is an old Vivitar 283. I've been testing with various camera equipment to find my problem but could use some troubleshooting or educating on whythis isn't working.<br> <br /> Ideally (and isn't working) the setup is my Nikon D5300 with a FlashQ T1-S transmitter connected to the hot shoe. The receiver is attached to a hotshoe to PC Wein safesync. The safe sync is connected to the Vivtar 283 by sync cable.</p> <p>Additional equipment for testing:<br /> A vivtar 2600 (simple ISO foot, sync voltage around 160)<br />LumoPro LP180 flash (this is my other flash for my setup)<br />An old NIkormat with no hot shoe, but has a PC connector</p> <p>What works:<br /> LP180 with FlashQ<br />Vivitar 283 with Nikormat (using sync cable)<br />Both Vivitars fire when connected to Wein using either the Wein's test button or shorting its foot connectors.</p> <p>Other things that don't work:<br /> D5300 won't fire either Vivitar flash through Wein<br />When the 2600 is connected to the FlashQ the FlashQ can't fire it, but the ready light on the flash does momentarily go off when I try to.</p> <p>Any thoughts?</p>
