NL241 Wireless Network Link Interface

FIGURE 8-2. Bridge mode LoggerNet setup

8.2.2.5 Connect

You are now ready to connect to your datalogger using the

LoggerNet Connect

screen.

8.2.3 TCP Serial Server

The NL241 can tunnel RS-232 and CS I/O serial communications over Wi-Fi.

Any packet sent to the configured IP port will have the IP layer removed, and

the data is then directed to the serial connection.

8.2.3.1 Physical Setup

Using the supplied serial cable, connect the NL241

CS I/O

port or

RS-232

port

to the datalogger

CS I/O

RS-232

port, respectively. The NL241 will be

powered if connected via CS I/O. Alternatively, power the NL241 through the

barrel-connector jack located on the edge of the device. Connect the NL241 to

your local wireless network by attaching an antenna to the NL241

Antenna

connector. Ensure that the device is powered up by inspecting the Power LED.

8.2.3.2 Configuring the NL241

RS-232 Serial Server

Connect to the NL241 in

DevConfig

(see Section

Configuring the NL241
