For more information on analog signal connections

For more information on single-ended inputs, refer to the Guide to Signal Connections (this document is

available on our web site at www.mccdaq.com/signals/signals.pdf).

Analog ground terminals

The 10 analog ground (AGND) connections provide a common ground for all analog input channels and the

analog trigger (TRIG_IN).

Refer to the pinout diagram on page 14 for the location of the AGND terminal pins.

Digital input terminals (DI0 to DI7) and digital output terminals (DO0 to DO7)

You can connect up to eight digital input lines to screw terminals DI0 through DI7. You can connect up to eight

digital output lines to screw terminals DO0 to DO7. Refer to the pinout diagram on page 14 for the location of

these pins.

The eight input pins have 47 k resistors that you can configure to either pull-up or pull-down, or disconnected

with a jumper.
