2.19 – Connecting External Devices
The standard devices you should expect to plug into the motherboard are keyboards, mice, and
printer cables. The following diagram will detail the ATX port stack for the following board:
Although primarily to connect printers, the parallel printer port is also used for devices such as ZIP
drives, external CD-RW drives, scanners, and other external devices. Serial ports, also known as
COM ports, are primarily used to connect external modems and other RS-232C devices.
TIP: While the ports have been created to accept connectors in only one direction, make sure to
be careful when inserting connectors. At times, attaching connectors in the incorrect orientation
can damage, bend and or break the pins.
2.20 – Installing the Power Supply
There are two power connectors on your Tomcat K7M. By default, the Tomcat K7M requires that
you have an ATX / ATX12V power supply that has a 20-pin and a 4-pin power connector. Do not
use any other type of power supply.
