PPM-C407/Best Practices
Avoid Cutting the PPM-C407—Never use star washers or any fastening hardware that
will cut into the PPM-C407.
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.
Adding PC/104 Boards to your Stack
Be careful when adding PC/104 boards to your stack—Never allow the power to be
turned on when a PC/104 board has been improperly plugged onto the stack. It is
possible to misalign the PC/104 card and leave a row of pins on the end or down the
long side hanging out of the connector. If power is applied with these pins misaligned, it
will cause the I/O board to be damaged beyond repair.
Conformal Coating
Applying conformal coating to a WinSystems product will not in itself void the product
warranty, if it is properly removed prior to return. Coating may 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.
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 will have identical headers for different functions
and plugging a cable into the wrong header can have disastrous results.
