Hi Harris.I replied a couple of time to your last message and I am not sure if it went or not so here it is again.Thank you.

Thanks Harris.As long as I have the PC port for my flash gun I will be happy.The D100 .PDF manual shows the hotshoe voltage limits as 250 volts on page 105 if you happened to have it.
The voltage of my gun is less than 5.00 volts.
It is a Nissin 4800GT by the way.Thanks again,Ron G
