PCI-1718 Series User Manual 22
3.2.2 Channel Configuration, S/E or DIFF (SW2)The PCI-1718 cards offer 16 single-ended or eight differential analog
input channels. Slide switch SW2 changes the channels between single-
ended or differential input. Slide the switch to the left-hand position,
marked DIFF, for eight differential inputs (the default) or to the right-
hand position, marked S/E, for 16 single-ended inputs.
3.2.3 D/A Reference Voltage, int./ext. (JP11)Jumper JP11 selects reference voltage source for PCI-1718 cards’ D/A
converters. You can use the cards’ internal reference, or supply an exter-
nal reference.
When you set JP11 to INT, the D/A converter takes its reference voltage
input from the card's onboard reference. Jumper JP10 selects either -5 V
or -10 V onboard reference voltage. With JP11 set to INT the D/A chan-
nel has an output range of 0 to +5 V or 0 to +10 V, respectively.
