Interface Parameters
If your data acquisition device interface is set up for Network (ethernet), you should
change the device interface to RS-232 serial communications prior to performing
calibration. Refer to your hardware setup chapter as needed.

Select the DIP Switch toolbar icon to activate the Interface Parameters window. This allows you to
select and setup the communication interface used for your scanning system. Once the icon is selected,

correspond to the chosen interface. Click the Verify box to make sure the settings are correct.

selection (from the

pull-down menu or toolbar). The settings and
constants will be stored in a file with a
