The DT9150 represents the state-of-the-art approach
to VXI product development and manufacturing. Taking
advantage of the robust feature set of the IT9010M
VXIntegrator廬 chip, the DT9150 combines all of the el-
ements necessary to implement a full message-based VXI
interface, with a minimum of space and effort.
The IT9010M provides all of the configuration regis-
ters and message-based device registers required by the
VXI specification. Also included are control circuitry,
arbitration between the VXIbus and the module's local
bus (microprocessor bus), bus master support, and sup-
port for the Analyzer Registers used in VME shared ac-
cess RAM operations. Required and optional functions,
such as Read Ready and Write Ready violation detection,
Data and Signal Register Location Monitors, and a Mul-
tiple Query Error Flag are all provided on chip.

User Interface
The DT9150 provides a compact message-based VXI
interface implemented on 13.5 square inches of board
space. This leaves 90+ square inches of unrestricted de-
sign space on a standard C-size module, plus 10 sq. in. of
additional space available under the DT9150. Optional
RS-232 port can be used with many development pack-
ages for source level debugging.
