Configuring the Excitation Jumpers
You can configure each excitation channel of the SCXI-1121 module to
either a voltage or current excitation mode. Each channel has two jumpers
for this purpose. Set both jumpers in the same mode for correct operation
of the excitation channel. Refer to Table 5 to determine how to set up the
module in the mode you want. The SCXI-1121 module ships to you in the
voltage mode.
