NL241 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 TCP services are available. In bridge mode, only
the Wi-Fi settings are valid. 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 NL241 antenna connector. Using the supplied serial
cable, connect the NL241
CS I/O
port to the datalogger
CS I/O
port. Ensure
that the device is powered up by inspecting the LED.
8.2.2.2 Configuring the NL241
Connect to the NL241 in
DevConfig
(p.
). In the NL241 tab, set
Bridge Mode
to
enable
.
In bridge mode, the IP address, subnet mask, and IP gateway to be
used by the NL241 are configured in the datalogger.
8.2.2.3 Configuring the Datalogger
1.
Connect a serial cable from the computer COM port to the datalogger
RS-232
port.
2.
Open
DevConfig
. Select the device type of the datalogger (CR800,
CR1000, or CR3000), the appropriate
Communication Port
, and the
Baud Rate
. Click
Connect
to connect to the datalogger.
3.
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 NL241 is CS I/O IP Interface #2 (SDC1). DNS server
settings are shared by all active IP interfaces and can be entered on the
Ethernet
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 info box
on the
Ethernet
and
CS I/O IP
tabs.
4.
Press
Apply
to save the changes and then close
DevConfig
.
