KIV-7M Interface Unit (KIU)


The KIV-7M Interface Unit (KIU) is a custom encryption and decryption interface unit. The KIU provides a network interface to the KIV-7M, and other similar units.

  • Provides a LAN interface to facilitate access by multiple computers to the KIV-7M over the LAN (both collocated and remote).
  • Translates data received over the Local Area Network (LAN) using TCP/IP communications socket protocol into the clock, data, gate protocol used by the KIV-7M unit using its RS-422 ports.
  • Enables the connection of an Ethernet Interface to the KIV-7M
  • Provides a key management function to map spacecraft and key indices to memory locations within the KIV-7M unit. This supports using the same KIV-7M unit for multiple spacecraft and eliminates the need for key management by an external control computer.
