The digital input terminals (labeled "Ch1 Din"..."Ch10 Din") are used to sense a digital high or digital low
state; or to measure the period of a changing digital signal. The inputs are protected
against high voltages up to +6Volts and down to -6V. To measure the logic level or the
period of an input signal, connect it directly to a Controller Din terminal and then connect
the signal source ground to a Controller Gnd terminal. For details, please see
Working with i200 Controller Digital Timer I/O Channels and
Working with Digital I/O Channels.

i200 PCI Card Installation
To install an i200 PCI card into your computer, please do the following steps:
Make sure computer power is OFF.
Remove the cover from your computer to gain access to the card slots.
Remove the small I/O fence cover from the back of your computer, as needed.
If you require access to an available Controller Digital/Timer I/O Channel, run a 34-wire ribbon
cable from the Controller's 34pin header connector, out of the computer, any way you can
(e.g. through another slot opening), to the breakout of your choice (e.g. a screw terminal block), as illustrated below:
Install the i200 instruNet controller(s) into the computer's expansion slot(s).
Make sure the Controller connector is well seated and inspect this
connection with a strong light to make sure the printed circuit board fingers are aligned with their mating connector pins.
Bolt the board metal I/O fence to the computer, as needed (some computers do this).
Please skip this step if tightening this bolt causes the card to not seat well in its connector.
