Note

You may wish to use the AirPal Link Budget tool provided on the

AirPair Toolkit CD ROM or the Link Budget Tool included with the

PDA software.

4.2.1. Power Output

The Output Power (P

out

) and the Effective Isotropic Radiated Power (EIRP) are

located on the Transmit path. The P

out

is at the radio flange. The radio flange

connects to the antenna waveguide. EIRP is at the antenna output.

Table 4-1 shows output power (P

out

) in both dBm and mw for the UL AirPair 50

and AirPair 100 radios.

4.3. Command Line Interface

A Command Line Interface (CLI) is available through the modem serial port. The

CLI is accessed through a terminal emulation package such as HyperTerminal

The user may also use an intuitive Graphic Unit Interface (GUI).

4.3.1. Configuring the Serial Port using the CLI

This section describes how to connect the AirPair to a PC using a straight-

through DB9 serial cable.

Procedure 4-1

Configuring the Serial Port using the CLI

Follow the steps below to access the AirPair CLI using a terminal emulation

program such as HyperTerminal.

1. Connect the serial cable from the DB9 serial port on a PC to the Serial port

on AirPair UL-100. The DB9 connector on AirPair is female; the cable from

the PC is male. A straight-through cable is required.

2. Start HyperTerminal or another terminal emulation program.

3. Set the terminal emulation program to emulate a VT100 terminal with the

following settings:
