EBM/EBM2 Interface with XDIF relay board
The EBM/EBM2 EQ section supports an eight-bit read/write data interface to the XDIF relay board. The
interface is used to transfer commutator control information to the selected probe and provides host
access to the XDIF relay board itself. The EBM/EBM2 board monitors four probes present and four
probe hook lines from the XDIF relay board. The EBM/EBM2 EQ section monitors the lines, and
generates an interrupt signal when any of the signals change state. The interrupt signal will be
debounced to limit the frequency with which probe interrupts may be generated. The EBM/EBM2 board
also measures the temperature of the selected probe over two lines from the XDIF relay board. The
SCE pulse signal connected to the EBM/EBM2 EQ section in order to be able to support the Global
Beamforming future development.
