According to what I am seeing on a popular Konica Minolta forum, this is not a simple subject.
Here are some threads that should help:

I'm trying to use a slave flash with the Dimage A2 that triggers from the A2 on camera flash. I can get the slave to fire, but am unable to get a properly exposed image. They are always too dark. I'm working in Manual mode for exposure. Manual Flash Control for flash and have used both Fill Flash and Rear Flash Modes with the same result.
I'm using a slave that worked perfectly with my Fuji FinePix S602. And have tried those settings in the same studio set up with the A2. That should have eliminated synch and exposure issues.
Do I have to go the PC route for 1 of the flashes? What settings am I missing? Any help is appreciated.
TIA
