Image Port Board (IMP)
The function of the Image Port (IMP) is to receive signals from either the RFT (during scanning) or the
VCR (during playback), capture them, and route them to the Back End Processor (BEP) via the PC2IP
Bus. The IMP handles all the communication from the BEP to the Front End Cards and back through
the VME Bus - see
The IMP is used as a connection to the BEP. All the instructions to the Front End Crate are sent via the
IMP, and all the outgoing data is transferred to the BEP via the IMP through the PCI Bus.

Back Plane Board (Motherboard)
The Back Plane Board serves as a mother board which connects all the boards’ signals. It also
distributes the low voltages for the FE Crate boards and the TX voltages. It hosts all the FE boards, as
shown in the following figures:
