Configuring the Gain Jumpers
Each input channel has two user-configurable gain stages. The first-stage
gain provides gains of 1, 10, 50, and 100. The second-stage gain provides
gains of 1, 2, 5, 10, and 20. The device ships with the first-stage gain set to
100 (position A) and the second-stage gain set to 10 (position D).
To change the gain setting of a specified channel on the module, refer to
Table 2 for the jumper reference designator of the channel gain stage you
want to change, and Figure 3 for the location of this jumper. Move the
jumper to the position indicated in Table 3.
