Setup and Operation: Dell OptiPlex GX1 Small-Form-Factor System User's Guidefile:///C|/infodev/2013/eDoc/OpGX1/UG/setup.htm [2/21/2013 11:47:10 AM]11Serial port 1 connectorWhen you connect external devices to your computer's back panel, follow these guidelines:Check the documentation that accompanied the device for specific installation and configurationinstructions.For example, you must connect most devices to a particular input/output (I/O) port or connector tooperate properly. Also, external devices like a mouse or printer usually require you to load devicedrivers into system memory before they will work.Always attach external devices while your computer is turned off. Then turn on the computer beforeturning on any external devices, unless the documentation for the device specifies otherwise. (If thecomputer does not seem to recognize the device, try turning on the device before turning on thecomputer.)NOTICE: When you disconnect external devices from the back of the computer, wait 5seconds after turning off the computer before you disconnect any devices to avoidpossible damage to the system board.Parallel Port ConnectorThe integrated parallel port uses a 25-pin D-subminiature connector on the computer's back panel.This I/O port sends data in parallel format (where eight data bits, or one byte, are sent simultaneously overeight separate lines in a single cable). The parallel port is used primarily for printers.The default designation of your computer's integrated parallel port is LPT1. Port designations are used, forexample, in software installation procedures to identify the port to which your printer is attached, thus tellingyour software where to send its output. (An incorrect designation prevents the printer from printing or causesscrambled print.)NOTE: The integrated parallel port is automatically disabled if the system detects an installedexpansion card containing a parallel port configured to the same address as specified in the ParallelPort option in the System Setup program .Mouse ConnectorYour system uses a Personal System/2 (PS/2)-compatible mouse. The mouse cable attaches to a 6-pinminiature Deutsche Inductive Norm (DIN) connector on the back panel of your computer. Turn off thecomputer and any attached peripherals before connecting a mouse to the computer.A PS/2-compatible mouse works as does an industry-standard serial mouse or bus mouse except that it hasits own dedicated connector, which frees up the serial ports and does not require an expansion card. Mousedriver software gives the mouse priority with the microprocessor by issuing interrupt request (IRQ) 12whenever a new mouse movement is made. The drivers also pass along the mouse data to the applicationthat is in control.USB Connectors
