    Use the largest gauge wire that you can. Most connector manufacturers have a maximum gauge wire they recommend for their pins. Try going one size larger; it usually works and the extra copper will help your system perform properly over time. 140808 PRODUCT MANUAL PCM-VDX-2-512...
  • Page 72 Contact Points WinSystems’ boards mostly use connectors with gold finish contacts. Gold finish contacts are used exclusively on high speed connections. Power and lower speed peripheral connectors may use a tin finish as an alternative contact surface. It is critical that the contact material in the mating connectors is matched properly (gold to gold and tin to tin).
  • Page 73 If power is applied with these pins misaligned, it will cause the I/O board to be damaged beyond repair. 140808 PRODUCT MANUAL PCM-VDX-2-512...
  • Page 74 Every single board computer has an Operations manual or Product manual. Manual Updates Operations/Product manuals are updated often. Periodicially 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 single board computers will have identical headers for different functions and plugging a cable into the wrong header can have disastrous results.
