PC Connection w/ Multiple Dynon Products

[dodsond]

Do I need the PC connection for both the EFIS and EMS to update firmware or can I do it though one box and the DSAB? It appears that the HS 34 has a PC connection too. Do I need 1, 2 or 3 ports?

You need a port for each unit. The firmware updates are unit specific and do not go across the DSAB. So you need a port for the EFIS, EMS and HS34.
