Hope I canget some advice about a problem I'm having with the sync connector port on my ab800.

When I connect a cybersync receiver with a cable to the port it does not work. I have tried different receivers and two different cables with no success.

When I plug and unplug a cable the flash goes off but will not trigger with the receiver.

Thanks for any help!

Make sure the cord is pushed all the way into the jack. Push hard.

You can unplug the receiver from the cord and short the contacts with a paperclip. If the flash fires when you do this, you know the connection is good at the light.

I assume you have used the Cybersync system successfully with other lights so you know that part of the chain is good. If not, there are a half-dozen other possible causes.

I was giving a good push and all three of my receivers and cables worked fine with my other light. I will try again though. Of course this happened when I was setting up for a wedding reception, I had to use a 580exII with a receiver pointed at the back of the AB800 and use the optical slave. I will try the paperclip!

thanks

With any of these radio-based flash triggering systems, there are a lot of parts in the chain which makes it difficult to diagnose problems. For example, it's pretty easy to inadvertently switch channels on the Skyport transmitter.

After a quick visual check, about all you can do is swap out parts of the chain, one part at a time, until the culprit is discovered.
