3 Using Your Laptop

Your laptop’s unique modular architecture enables you to remove and replace your hard disk drive. See “Removing and Replacing Your Hard Disk Drive” on page 55.

Using the Infrared Communications Port

Your SA200 is equipped with an IrDA-compliant fast serial infrared (FIR) communications port on its left panel. See Figure 4 on page 8.

The FIR port allows wireless, serial communication between your laptop and other IR equipped devices such as a printer or another computer. The FIR port consists of two light emitting diodes (LEDs) that operate similarly to a television remote control device. One LED functions as a transmitter and the other acts as a receiver. The transmitter emits a signal consisting of data as pulses of infrared light; the receiver picks up pulses of infrared light transmitted by other IR ports.

Use the Windows 95 Terminal utility to transmit or receive data through the SA200’s FIR port. Refer to your Windows 95 documentation for instructions on using the Terminal utility.

Follow these guidelines when using your laptop’s FIR port to transmit or receive data:

•Ensure that the SA200’s FIR port is properly lined up with the other device’s IR port.

•Ensure that the distance between the SA200’s FIR port and the other devices IR port does not exceed one meter (three feet).

•Ensure that the angle between the two IR ports does not exceed 15 degrees.

•Ensure that there is a clear, unobstructed path between the two IR ports during data transmission. Obstructions will block the optical signal.

•Do not move either the SA200 or the other device during data transmission. Movement distorts the optical signal and results in the loss of data.
