Usb Devices; Parallel Devices - Dell Inspiron 2000 System Reference Manual

NOTE: If the computer is in suspend (or standby) mode or S2D mode when you attach an external keyboard, the device is recognized
immediately by the computer when it resumes normal operation.
You can use the computer's keyboard and an external keyboard at the same time. When you attach a keyboard to the computer, the embedded
numeric keypad is automatically disabled.
On an external keyboard, the <Scroll Lock> key acts the same way as the <Fn> key on the computer's keyboard (if the
enabled in the system setup program).
External Numeric Keypad
NOTE: If the computer is in suspend (or standby) mode or S2D mode when you attach an external numeric keypad, the device is
recognized immediately by the computer when it resumes normal operation.
When you attach an external numeric keypad to the computer, the numeric keypad on the computer keyboard is automatically disabled. The
indicators on the integrated keyboard track the operation of an external numeric keypad.

USB Devices

You can attach a USB hub device to the USB connector. The USB hub device can support multiple USB devices (typically low-speed peripherals
such as mice, keyboards, printers, and computer speakers).

Parallel Devices

You can attach a parallel device (usually a printer) to the 25-pin parallel connector. You can also connect the diskette drive to the parallel connector.
The parallel port sends and receives data in parallel format, where eight data bits (one byte) are sent simultaneously over eight separate lines. The
port can be configured as a unidirectional (output-only) port for devices such as a printer or as a bidirectional port for devices such as a network
adapter.
The computer's integrated parallel port is designated as LPT1. The Microsoft® Windows® 98 operating systems automatically recognize the
parallel device and configure it correctly. The parallel port can also be configured for compatibility with the PS/2 standard.
Connecting a Diskette Drive to the Parallel Connector
You can use the diskette drive as a second external device if you already have a device connected to the media bay connector. The diskette drive
letter is A, unless a diskette drive is already installed in the external media bay, in which case the drive connected to the parallel connector is drive
B.
To connect the drive to the parallel connector on the I/O panel, use the optional parallel diskette-drive cable (available from Dell), as shown in
Figure 2.
Figure 2. Connecting a Diskette Drive to the Parallel Connector
NOTICE: When the diskette drive is not being used externally, remove the parallel diskette-drive cable from the parallel connector.
NOTICE: Use the parallel diskette-drive cable only with the diskette drive. Do not try to connect any other device to the computer
with this cable.
