The PHM touchscreen monitor can be used with the headless XPR or XPR2 units as its display and touchscreen. However, the XPR/XPR2 unit must be configured for this combination first (out of the box it will not be).
Remove the Compact Flash card from the XPR/XPR2 unit and run the flash back utility (see link to Flash Back Archives below). Find the version that you are using and run the utility in the XRPT&XPR2T folder. This is the version for use with the PHM external touchscreen.
Now transfer your application back to the CF card. Plug in a VGA cable between the XPR/XPR2 headless unit and the PHM and an RS232 cross over (null modem) cable between the PHM and the COM1 port on the XPR/XPR2 unit.
