Serial Port Connectors Default port designations: COM1 for serial port 1 and COM2 for serial port 2. You can reassign the serial port's designation if you add an expansion card containing a serial port using this designation. If you set the computer's serial ports to Auto in system setup and add an expansion card containing a serial port configured to a specific designation, the computer automatically maps (assigns) the integrated ports to the appropriate COM setting as necessary. Before you add a card with a serial port, check the documentation that accompanied your software to make sure that the software can be mapped to the new COM port designation. Keyboard Connector Attach the keyboard cable to the 6-pin connector on the back panel. Video Connector This connector is used to attach a video graphics array (VGA)-compatible monitor to your computer. NOTE: This connector can be used for a secondary display if multi-monitor is supported and enabled in your operating system and you have an add-in PCI video card. 28 Abo u t You r C o mp u t er
