3.8 Verifying the Installation

For verification of the installation, leave any switches or jumpers not mentioned above in their default
positions. Each of the gain switches (CH0 through CH7 and S17-7) should be off (toward the upper edge
of the board) for a gain of X1 (unity gain). The channel configuration switches (labeled “IN CONFIG”
should be left in the default position (the switches labeled “4” in the ON position and those labeled “3”
in the OFF position - the label is printed on the board, not the switch).

To verify the installation, use the InstaCal program installed on your computer. This software came with
your A/D board if you bought the board from the same manufacturer as the CIO-EXP-GP. If your A/D
board is not from the same manufacturer but is compatible, please call technical support and request a
copy of InstaCal.

Use InstaCal's TEST option to verify that a signal present at one of the CIO-EXP-GP inputs can be read.
You will not need to set any jumpers other than those previously mentioned, and should not set any
switches or install any passive components until you have verified the installation.

When using an AC signal source, keep the frequency below 70Hz to avoid attenuation by the low pass
filter.
