Xterm has a White screen or Black Screen

When using Xterm to talk with a Xpert, if the screen area does not show the login prompt or
menus:

Black screen- This indicates the unit is not communicating. Check that the unit has power and
that the serial cable is connected. Also check that the correct com port and baud rates have been
selected.

White screen- This indicates that Xterm is communicating with the Xpert, but no program is
running. First try right-clicking into the screen area to ensure the screen is updated. Check that
the unit has an autoexec.bat by using file transfer, if it doesn't, send one to the unit (either create
one following APPENDIX F or get it from the web site) and reboot it. If it does have one,
transfer it to the pc and edit it to make sure it has the line \Flash Disk\Xpert.exe in it. If the unit
has the autoexec.bat and it has the line to run the xpert.exe in it, then close xterm, run a terminal
program (@ 115200,8,N,1) and reboot the Xpert. You should see the very last line of bootup
information showing:

Launch complete.

If you do not see this, or get any other errors, contact customer service for further assistance.

Adjust the contrast

On power up, the Xpert starts with the contrast at a fixed value. You may change the contrast
either at the login screen or at the main tab of the Xpert. When the login screen is displayed,
tapping the touch screen in the upper right corner will darken the contrast while tapping the
touch screen in the lower right corner will lighten the contrast. Wait at least 2 seconds between
each tap to give the display a chance to adjust to the new contrast setting.

At the main tab of the Xpert you will find a display of the contrast voltage and two buttons to
press to adjust the contrast. Pressing <= will lighten the contrast and pressing => will darken it.
The corresponding voltage will also be displayed.

Replace the Internal Battery every 5 years

DISCONNECT POWER

before opening the unit.

The Xpert has an internal lithium battery to keep the clock running when power is removed. This
battery should be replaced every 5 years as a preventative measure. Typically, on a unit that is
sitting on the shelf with no power applied, the battery will last for 9 years. The 5 year
recommendation is intended to provide a margin for the worst case situations. The battery is a 3
Volt, BR2330 type coin cell.

Upon power-up, the RTC date and time validity are checked. If determined to be invalid, the
unit will set the date to 1/1/1984. A unit that sets its date to 1984 needs to have its internal
battery checked and most likely replaced.

To replace the battery, remove power from the unit, remove the 8 screws holding the bottom of
the case to the top, slide the bottom out of the top, locate the battery, use a small screwdriver to
help lift the battery out of the holder, slide the new battery into the holder.
