Hi Bob_Schor,
The uniblitz VMM-D3 is a three channel shutter driver that is built of one com port. The software is only setup to control the 1st channel of the driver. The way i think this software should be modified is that we should have a selector that controls the shutter channel in the front pannel. My only problem is that i have little expereance progaming.
I have attached the user manule and also copied the webpage for this shutter driver to this post.
