HARDWARE CONFIGURATION

Before an acquisition board can work properly with the DLL driver software, it must be configured correctly.  You must determine the hardware options (range(s), I/O address, etc.) which suit your particular requirements.  On all ADVANTECH boards, configuration is a matter of setting jumpers and switches. Read the manual that comes with your ADVANTECH board in conjunction with this help to determine how to configure the hardware.   All ADVANTECH boards are shipped with factory default settings.  If the default configuration is appropriate for your system, no additional set-up is required.

Configuring the PCL-726, PCL-727, or PCL-728

The following options must be configured on the cards before they can be used with the Advantech DLL driver:

*  Base Address

*  D/A Reference Voltage and Range

*  Special wiring considerations if 0-20mA or 4-20mA ranges are selected (see hardware manual)

After the hardware jumpers are set, you must configure this driver to agree with those settings.

If external reference is selected, the reference value and whether the desired range is bipolar or unipolar must be provided during runtime via the corresponding variables in the Analog Output parameter structure, or through the application program, if supported.

If 0-20mA or 4-20mA ranges are selected, the values provided for analog output during runtime should be in terms of milliamperes; ie. for 10 mA, just send a 10 from the application.
