2.9   Connecting External Devices 

Connecting external devices to the motherboard is an easy task. The standard devices you 

should expect to plug into the motherboard are keyboards, mouse, and printer cables. The 

following diagram will detail the ATX port stack for the following board:

Besides being used primarily to connect printers, the Printer Port is also used for devices such 

as Zip drive, some external CD RW drives and or other external devices.  More on the 

uncommon side these days are the Serial Ports.  They were primarily used to connect external 

modems, but most modems today are using USB or are installed internally. 

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.
