3500 Series Flat Panel Industrial PC

On a 1024 x 768 display, the stretching algorithm does not completely fill the display
horizontally or vertically. You can achieve a greater vertical text expansion by changing
to VGA mode 3* (see Note below). This is an 80 column, 25 row text mode with an ef-
fective resolution of 640 x 350. The 350 lines stretch better to fill the 768 line display.
Note
The utility disk includes the
MOD3_350.EXE utility, allowing you to
switch to VGA mode 3*. The MOD3_400.EXE utility allows you to
change the mode back to the DOS default of 3+.
Windows may come up with a blank screen when using Windows 3.X on a unit, with ex-
pansion turned on either through the BIOS setup menus or using the EXP_ON.EXE utility.
There are two available options (second option being the best) to resolve this situation:
•
Press the
CTRL
-
ALT
-
DEL
keys simultaneously. When the Windows message appears,
press any key to return to Windows. The Windows screen should appear.
•
Turn off the expansion.
•
Default to factory settings in the BIOS setup menus.
•
Use the appropriate utility as shown in the
Video Expansion Options
table.

Mounting Considerations
This section describes issues you must address before placing the unit inside an enclosure.
Consider the following
points and precautions:
•
Select an enclosure and place the unit to allow easy access to the ports.
•
Account for the unit’s depth when choosing the depth of the enclosure.
•
Provide a NEMA 4 seal by mounting the unit in an approved enclosure with a 14
gauge (0.075"/1.9mm thick) steel or (0.125"/3.2mm thick) aluminum front face.
•
Mount the unit in an upright position.
•
Place the unit at a comfortable working level.
•
Consider locations of accessories such as AC power outlets and lighting (interior
lighting and windows) for installation and maintenance convenience.
•
Prevent condensation by installing a thermostat-controlled heater or air conditioner.
•
To allow for maximum cooling, avoid obstructing the airflow.
•
Place any fans or blowers close to the heat generating devices. If using a fan, ensure
that outside air is not brought inside the enclosure unless a fabric or other reliable
filter is used. This filtration prevents conductive particles or other harmful contami-
nants from entering the enclosure.
