Configuration Using a USB Cable

Evaluation boards use a USB cable to allow the host computer to communicate with the

on-board RN module.

The following instructions describe how to use a terminal emulator to enter Configuration

mode, send commands to find networks, associate with an access point, and save the

configuration.

2.3.3.1

CONFIGURE THE MODULE USING A TERMINAL EMULATOR

Either the TeraTerm (for Windows 7 or later) or CoolTerm (for Mac OS X or later)

terminal emulator applications can be used. Also, legacy evaluation boards use a

USB-to-serial cable for connecting the evaluation board to the PC/laptop. When using

any of the evaluation boards, use the COM port to which the USB-to-serial cable is

connected.

Use the following steps to communicate with an RN module using a terminal emulator:

Determine the COM port that is assigned to the USB cable (the port is COM9 in

the example shown in Figure 2-2).

Open the available terminal emulation application and specify the COM port.

When using TeraTerm, open the Serial option and select the COM port number

from the drop-down menu.

The serial port with the required settings are as follows:

• Baud: 9600

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: None

Type the commands through the terminal emulator application and to the

assigned program.

Note:

The COM port number can be found as follows:

• For Windows: Go to the Windows Device Manager from System Tools. In the

Device Manager, browse and expand the selection for serial ports (COM &

LPT). Use TeraTerm for other configuration settings and monitoring.

• For Mac: When using CoolTerm, view and select the port from the same

terminal emulator application.
