The Astronics / C&H Technologies VX405C M/MA Module Carrier is a VXIbus-resident carrier that provides mechanical and electrical interfacing for up to six VITA 12-1996 standard M/MA modules within a single VXI slot. The carrier manages VXI register configuration and delivers independent I/O space and memory access to each installed module, with individual logical addressing enabling flexible instrument integration. Each M/MA module operates as a distinct logical address within the VXI environment, supporting custom UUT interfacing through a library of over 200 available modules.
