I have a Nikon D200 and two flash units. One attaches to the Hotshoe and the other with a PC sync cable. The one on the cable is old and has a 234V trigger. The other flash is a Nikon SB-20 with a 5.5V trigger. Will I have to add these voltages up to see if it's under the rated max voltage (Which is 250V. I know they add up to less than that but I'm a bit oo err with the old flash by it's self) or do the connectors have their own separate max voltages? Thanks
