That means it should flash when it sees another flash go off, right? I haven't been able to get that to work either.</P> Mon, 05 Mar 2018 17:09:57 GMT deanadeana 2018-03-05T17:09:57Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Can-t-figure-out-how-to-get-600EXII-RT-and-320EX-to-cooperate/m-p/237618#M40393 <P>Hello,</P><P>&nbsp;</P><P>I have a Canon EOS 6D, a ST-e3-RT speedlite transmitter, a 600EXII speedlite, and an old 320EX speedlite. The camera, transmitter, and 600EX work together just fine, but I cannot for the life of me figure out how to get the 320EX to fire. I only have one flash group, the transmitter is set to master, and the two flashes are set to slave. Please help? Thanks!</P> Mon, 05 Mar 2018 16:26:22 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Can-t-figure-out-how-to-get-600EXII-RT-and-320EX-to-cooperate/m-p/237618#M40393 deanadeana 2018-03-05T16:26:22Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Can-t-figure-out-how-to-get-600EXII-RT-and-320EX-to-cooperate/m-p/237620#M40394 <P>I don't believe that the 320EX has a radio receiver, only optical.</P> Mon, 05 Mar 2018 17:08:11 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Can-t-figure-out-how-to-get-600EXII-RT-and-320EX-to-cooperate/m-p/237620#M40394 kvbarkley 2018-03-05T17:08:11Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Can-t-figure-out-how-to-get-600EXII-RT-and-320EX-to-cooperate/m-p/237621#M40395 <P>Okay, great!

It only fires when it sees a specially coded burst from an optical master.</P> Mon, 05 Mar 2018 17:44:48 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Can-t-figure-out-how-to-get-600EXII-RT-and-320EX-to-cooperate/m-p/237625#M40396 kvbarkley 2018-03-05T17:44:48Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Can-t-figure-out-how-to-get-600EXII-RT-and-320EX-to-cooperate/m-p/237657#M40397 <P>Oh, well, that explains it.
