Dell OptiPlex GX150 - Manual (Page 8)

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 system ’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.
