Hardware Installation
You can install the SCXI-1120 in any available SCXI chassis. After you have made any
necessary changes and have verified and recorded the jumper settings on the form in
Appendix G, Customer Communication, you are ready to install the SCXI-1120. The following
are general installation instructions, but consult the user manual or technical reference manual of
your SCXI chassis for specific instructions and warnings.
1. Turn off the computer that contains the data acquisition board or disconnect it from your
SCXI chassis.
2. Turn off the SCXI chassis. Do not insert the SCXI-1120 into a chassis that is turned on.
3. Insert the SCXI-1120 into the module guides. Gently guide the module into the back of the
slot until the connectors make good contact. If a cable assembly has already been installed in
the rear of the chassis, the module and cable assembly must be firmly engaged; however, do
not force the module into place.
4. Screw the front mounting panel of the SCXI-1120 to the top and bottom threaded strips of
your SCXI chassis.
5. If this module is to be connected to an MIO-16 data acquisition board, attach the connector at
the metal end of the SCXI-1340 cable assembly to the rear signal connector on the
SCXI-1120 module. Screw the rear panel to the rear threaded strip. Attach the loose end of
the cable to the MIO-16 board.
Note: For installation procedures with other SCXI accessories and data acquisition boards,
consult Appendix E, SCXI-1120 Cabling.
6. Check the installation.
7. Turn on the SCXI chassis.
8. Turn on the computer or reconnect it to your chassis.
The SCXI-1120 board is installed and ready for operation.
