Additional information

VIS-320/E armored Vehicular Intercommunication System is considered to establish voice communication as the main function of the system between the commander and crews of an armored vehicle/tank. In addition, by connecting this system to the two radios and Infantry Box (IB), external communication can be established for commander and the crews.

VIS-320/E includes Central Unit (CU-320), Commander Terminal Unit (CTU-320), Crew Member Terminal Unit (CMTU-320), Gunner Terminal Unit (GTU-320), Infantry Terminal Unit (ITU-320), and External Loudspeaker (EL-320). Access of the crews and infantry to the radio 1 is gained by the commander via the Commander Terminal Unit. In this case, Crew Member/Infantry Terminal Units are under control of the Commander Terminal Unit completely. Access of the gunner to the radio 1 is gained via the Gunner/Commander Terminal Unit. Access of the crews to intercommunication is selected by available chest set of them. In all intercommunication and external communication, the commander is in high priority and can gain its special access.
