6 SYSTEM CONNECTIONS AND JUMPER PIN BLOCKS
6.1 System Connections
Notes:
3. Connecting to the PC through a USB hub is not recommended.
4. See Section 1.8 on page 5 for more information on configuring these headers.
5. These connectors are part of the optional passive differential input filter network and are not used by
default. Refer to Section 4.2 on page 15 for more information.
6. When using the default active single-ended-to-differential analog input filter, only the pins labelled “+”
(signal) and “G” (ground) are used. When using the optional passive differential filter, all three pins
are used. This connectivity is shown in Figure 13 on page 26 and Figure 14 on page 27.
