Channel mode switch
Switch S1 configures the analog inputs of the PCIM-DAS16JR/16 as either eight differential channels or
16 single-ended channels. Set the switch to single-ended mode if you have more than eight analog inputs to
sample. Setting the switch to differential mode allows up to 10 volts of common mode (ground loop) rejection
and provides better noise immunity.
The channel mode switch is factory-configured for eight differential inputs (see Fi .) To configure for
16 single-ended channels, set this switch to " SE ".
