The IVM (4.00K last Ver) has to have a AVC card. The Imagen would need to be Ver 5 or 5.50 to operate correctly. I have seen 6.00D on the 5 system but dont suggest using it.The DVC card is needed for the Imagen VM and there are 4 different cards, 2 port full 2 port expansion 4 port full and 4 port expansion. The expansion cards dont have Data connections. 2 4 port full cards can be used to make a 8 port but 2 2 ports cant be used to make a 4 port. Cable for Data and Cable for Voice Channels are easy to make up. For installation and or system programming help drop me a email info in profile.
