•
Never use screws with oversized heads. The head could come in contact with
nearby components causing a short or physical damage.
•
Never use self-tapping screws; they compromise the walls of the mounting hole.
•
Never use oversized screws that cut into the walls of the mounting holes.
•
Always use all of the mounting holes. By using all of the mounting holes, you
provide the support the embedded computer module needs to prevent bending or
flexing.
Plug or unplug connectors only on fully mounted boards
—Never plug or unplug
connectors on a board that is not fully mounted. Many of the connectors fit rather
tightly and the force needed to plug or unplug them could cause the embedded
computer module to be flexed.
Avoid cutting the
ITX-P-3800
—Never use star washers or any fastening hardware that
cut into the ITX-P-3800.
Avoid over-tightening of mounting hardware
—Causing the area around the mounting
holes to compress could damage interlayer traces around the mounting holes.
Use appropriate tools
—Always use tools that are appropriate for working with small
hardware. Large tools can damage components around the mounting holes.
Avoid conductive surfaces
—Never allow the embedded computer module to be placed
on a conductive surface. Many embedded systems use a battery to back up the clock-
calendar and CMOS memory. A conductive surface such as a metal bench can short the
battery causing premature failure.
Conformal Coating
Applying conformal coating to a WinSystems product does not in itself void the product
warranty, if it is properly removed prior to return. Coating can change thermal
characteristics and impedes our ability to test, diagnose, and repair products. Any
coated product sent to WinSystems for repair will be returned at customer expense and
no service will be performed.
Operations/Product Manuals
Every single board computer has an Operations manual or Product manual.
—Operations/Product manuals are updated often. Periodically check
) for revisions.
Check Pinouts
—Always check the pinout and connector locations in the manual before
plugging in a cable. Many I/O modules have identical headers for different functions and
plugging a cable into the wrong header can have disastrous results.
Contact an Applications Engineer
—If a diagram or chart in a manual does not seem to
match your board, or if you have additional questions, contact a WinSystems
Applications Engineer at +1-817-274-7553.
