rigid by design, and flexing or bending the embedded computer module
can cause the BGA to tear away from the printed circuit board.
Avoid cutting the PPC12-427
—Never use star washers or any fastening
hardware that cut into the PPC12-427.
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.
Adding WINSYSTEMS Modular IO80 Boards
Be careful when adding Modular IO80 boards to the PPC12-427
—
Never allow the power to be turned on when a Modular IO80 board has
been improperly plugged onto the PPC12-427.
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 embedded computer and panel PC has an Operations manual or
Product manual.
Periodic updates
—Operations/product manuals are updated often.
Periodically check the WINSYSTEMS website (
http://www.winsystems.com
)
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 system, or if you have additional questions,
contact a WINSYSTEMS Applications Engineer at +1-817-274-7553.
