580 EXII won't trigger via PC cable when set up as master in manual mode

<p>Hi,<br>

I'm trying to trigger a 580 EXII via a PC sync cable and it won't work if the flash is set up as a wireless master in manual mode. I've searched and can't find anything on this. Works fine if set up as master in ETTL or as non-master in either ETTL or manual modes.<br>

I'm trying to set up a two flash system with a Mamiya RB67 Pro SD. The idea was to trigger the 580 via cord and trigger a 480 EXII as a wireless slave (both flashes in manual mode). NOTE: It actually works if I connect a wireless transmitter to the Mamiya PC socket and a receiver to the 580 via the hot shoe connector, so the problem with this mode seems to be the PC sync connection. Anyone seen this before?<br>

Thanks.</p>

<p>I'm pretty sure the 580 needs to be mounted to a hot shoe to function as a master. The wireless trigger is essentially the same as hot shoe mounting, which is why that worked for you.</p>

<p>Yes thanks, although this seems to be the case only in manual flash mode. Works fine as master in ETTL from the PC socket (580 fires), but I didn't check if the slave also fires in this mode.<br>
