Types of Cable and Example Connections
The connector used for COM8-(PCI)H 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.
Differences to the COM-2(PCI), COM-4(PCI), and COM-8(PC)
The COM-2(PCI)H, COM-4(PCI)H, and COM-8(PCI)H boards are an enhancement of the previous COM-2(PCI), COM-4(PCI), and COM-
8(PCI) board models and are upwardly compatible with the COM-xx(PCI) boards. Accordingly, the boards can generally be used in the same way
as the COM-xx(PCI) boards.
There are some differences in the specifications.
Please refer to the EXAR Corporation data sheet for details about the LSI used on the boards.
