In general:
± DIFF n lines are the differential inputs for each channel. Shielded
RFI GND/Drain Shield n are the grounds for the shield on the
RFI GND/Cable Shield are the grounds for a shield around the entire cable and the ground points for making individual channels
I2C_xxx supply control signals to the active break out boxes. Support is not provided for any other use. These are not used with the VT3240/1A Voltage and Voltage/ ICP® break out boxes.
RFI GND/I2C Shield protects the analog input lines.
BOB_EN is another break out box control signal. Support is not provided for usage with anything except certain VXI
CAL_HIGH/LOW are signal lines to send calibration signals to the
VXI
±24V Power and GND supply power to the signal conditioning circuitry in the active break out boxes and ICP® in the active ICP® break out box. The power available on these lines is not specified and their usage is discouraged.
