Chapter 3 Configuring Your SCXI Hardware and Software
© National Instruments Corporation 3-9 Getting Started with SCXI
jumpers. However, you must adjust the jumper configuration if any of the
following conditions is true:
• You are cabling this SCXI-1120/D directly to a DAQ device and you
are using a Lab or 1200 device, or you are using an AI or MIO device
in SE mode.
• You need gain or bandwidth different from the default value on any
channel.
• You are using digital modules in the same chassis and are cabling the
SCXI-1120/D to a DAQ device.
Read the rest of this section on the SCXI-1120/D module if any of the
previous conditions applies to you.
The SCXI-1120/D has 42 user-configurable jumpers, many of which
perform the same function but configure different channels. You can set the
jumpers to configure gain, filtering, temperature sensor signal routing, and
signal output referencing. Leave all other jumpers in the factory-default
positions.
Use the following procedure to configure your SCXI-1120/D module:
1. Configure the gains.
Each input channel has two user-configurable gain stages. The first
gain stage provides gains of 1, 10, 50, and 100, and the second stage
provides gains of 1, 2, 5, 10, and 20. Tables 3-4 and 3-5 show how to
set up the gain for each channel.
Table 3-4.
