NL240 Wireless Network Link Interface
8.2.1.4 Connect
You are now ready to connect to your datalogger using the LoggerNet Connect
screen.
8.2.2 Bridge Mode
With Bridge Mode Enabled, the device will act as a bridge from WLAN to CS
I/O. All IP packets that come into the device via WLAN will be
communicated as a complete Ethernet/TCP packet to the datalogger over the
CS I/O port. This enables the datalogger to use its TCP/IP stack to interpret the
packet and, therefore, all of the datalogger’s TCP services are available. In
bridge mode, none of the other device settings are valid and all other
functionality is disabled. All settings (that is, IP, netmask, gateway) are
configured in the datalogger. However, in bridge mode, the device will
intercept any TCP traffic on the TCP Configuration Port Number. This
allows the device to still be configured remotely by IP connection using
DevConfig. The TCP Configuration Port Number is a user setting with a
default value of 6786.
8.2.2.1 Physical Setup
Attach an antenna to the NL240 antenna connector. Using the supplied serial
cable, connect the NL240 CS I/O port to the datalogger CS I/O port. Ensure
that the device is powered up by inspecting the Power LED.
8.2.2.2 Configuring the NL240
Connect to the NL240 in DevConfig (see Section 7, Configuring the NL240). In
the NL240 tab, set Bridge Mode to enable.
In bridge mode, the IP address, subnet mask, and IP gateway to be
used by the NL240 are configured in the datalogger.
8.2.2.3 Configuring the Datalogger
• Connect a serial cable from the PC COM port to the datalogger’s RS-232
port.
• Open DevConfig. Select the device type of the datalogger (CR800,
CR1000, or CR3000), the appropriate Communication Port, and the
Baud Rate. Press Connect to connect to the datalogger.
• If using a static IP address, select the CS I/O IP tab and input the IP
address, subnet mask, and IP gateway for the correct CS I/O Interface.
The default for the NL240 is CS I/O IP Interface #2 (SDC1). DNS
server settings are shared by all active IP interfaces and can be entered on
the TCP/IP tab. These values can be provided by your network
administrator. If using DHCP, leave the CS I/O IP address settings as
0.0.0.0. You will find the information acquired by DHCP in the TCP/IP
info box on the TCP/IP tab.
• Press Apply to save the changes and then close DevConfig.
