1-2
The VMIVME-3124 occupies 128 bytes of short I/O VMEbus addressing
space. Jumpers are provided to place the board on any 128-byte boundary. The board
may also be jumper-programmed to respond to supervisory, nonprivileged, or both
accesses.
Conversion data is available from a 16-bit register (12-bit right justified with
optional sign extension). This data is stored in on-board dual-ported memory for easy
access.
The Built-In-Test (BIT) capability permits the user to verify the on-board ADC
using high precision user programmable reference voltages. Software must control
the BIT functions.
After a system reset, the board returns to a fixed configuration. All bits in the
Control/Status Register are cleared and the front panel FAIL LED is illuminated. The
LED must then be extinguished under software control. This LED can then be used to
visually locate a faulty board in a system.
