specify the chassis ID and module number of the VXI-SC-1000 and
VXI-SC submodule, exactly as if you were communicating with a
traditional SCXI chassis.
VXI-SC-1102 Submodule
The hardware features of this module are identical to those of the
SCXI-1102. See the SCXI-1102, SCXI-1102B, and SCXI-1102C section of
Chapter 14, SCXI Hardware, for more details.
VXI-SC-1102B and the VXI-SC-1102C Submodules
The VXI-SC-1102B and the VXI-SC-1102C are variants of the
VXI-SC-1102. They are functionally identical to the VXI-SC-1102
submodule except for their higher bandwidth support: 200 Hz for the
VXI-SC-1102B and 10 kHz for the VXI-SC-1102C, in comparison with to
the 2 Hz bandwidth limitation of the VXI-SC-1102.
VXI-SC-1150 Submodule
The VXI-SC-1150 submodule plugs directly into the VXI-SC-1000 carrier
module and holds up to four signal conditioning minipods (SCMPs). The
VXI-SC-1150 is designed to work in conjunction with other VXI-SC
submodules, such as the VXI-SC-1102, to support transducer conditioning.
When the VXI-SC-1150 is populated with the current excitation minipods
and voltage excitation minipods, you can use these sources to excite
transducers, including RTDs, strain gauges, thermistors, and resistances.
The VXI-SC-1150 is divided into four SCMP sockets. Each socket has two
connectors. The 24-pin connector provides excitation to the front panel
96-pin DIN connector. The other 28 pin connector supplies power and a
communication channel to the SCMP from the VXI-SC-1000 carrier
module.
Each SCMP has an individual ID that the VXI-SC-1150 recognizes
and passes along to Measurement & Automation Explorer, which reports
the ID to you. Therefore, you can use auto-configuration to control and
recognize your setup. In addition, the VXI-SC-1150 has its own module ID
(44 decimal) and its own VXI device ID (812 decimal).
