8-4 Installing the ACAO
11-12-01
DataShuttle and DynaRes
(For ACAO-12-8 boards, Channels Three and Four are paired similarly, as are Channels Five and Six
and Seven and Eight.)
The first range switch for each channel (Switch 1 or 3) selects unipolar or bipolar voltage outputs.
Down selects unipolar; up will output bipolar.
The second range switch (Switch 2 or 4) will determine whether the output will be 5 or 10 Volts. An
up setting selects 5 volts; down is 10 volts.
Note that the range switches do not effect current outputs. If you set a channel for current, it will
automatically output in the 4-20mA range.
See the tables below for detailed V/C switch settings.

1. U = Up D = Down
2. Switches 1 and 3 set the voltage ranges for Channels 1, 3, 5 and 7. Switches 2 and 4 set the ranges for
Channels 2, 4, 6 and 8.
* Selecting the ± 10V range is an error condition. This range can be used, but the output is not in ± 10V.
Output ranges from -10V at 20% to +10V at 100% of full scale. It does not go below approximately -11V at
16%.
Next Steps
Single Board Usage If you intend to run with a single data acquisition board in your system, you are now
ready to install your application software.
Multiple Board Usage If you are going to use more than one data acquisition board, now its time to set
each boards Board Number Switches to an unique number. Follow the steps in the Setting the Board
Number Switches section in this chapter on page 8 4.
Installing the Software For information on loading and configuring DASYLab or QuickLog PC please
refer to the user guide for that application package.
Installing the Terminal Panels To learn how to connect experiments to the terminal panel see your
terminal panel chapter, or the Applications chapter (which discusses data acquisition and control in general
and provides examples of uses for the products).
ACAOCAL must be used to initialize driver file.
Setting the Board Number Switches
Multiple Boards
When you are using multiple boards in your installation, each board needs to have an identity for the
software to recognize it as an individual.
The Board Number Switches on a board accomplish this, as they enable you to set an identifying number
for the board.
