Installing External Serial Port Device
The notebook contains an RS-232 serial port with a male DB-9 connector as
shown in Figure 2-7. The serial ports are used to interconnect such devices
as:
•
External Modem
•
Serial Printer
•
Any device that uses an RS-232 interface
To connect a printer to the notebook, ensure that both the notebook and the
printer are turned off.
c
Caution: Never connect a parallel device to a serial port or a serial de-
vice to a parallel port or video port; this may cause damage to the
Notebook and/or peripheral device. If you are uncertain of what type
connector the external device has, refer to the technical manual for the
external device.
