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.
