Types of Cable and Example Connections

The connector used for GCOM-8C2-PCI has a wide interpin space and is highly reliable. In the case of
a PC with a narrow slot opening, a gap might be created as wide as the thickness of the sheet metal of the
PC when an external cable is connected, preventing the connector from being fitted properly. If the
thickness of the sheet metal is less than 1.5mm (typically about 1.0mm), simply tighten the adjusting
screw located on the side of the connector to install it properly. The connector should function without
a problem.
