8.2.1.4 Connect
You are now ready to connect to the data logger 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 data logger over the CS I/O port. This enables the data logger to use its TCP/IP stack to
interpret the packet and, therefore, all of the data logger 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 data logger. 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
Device Configuration Utility
. The TCP Configuration
Port Number is a user setting with a default value of 6786.
8.2.2.1 Physical setup
As shown in
(p. 28), attach an antenna to the NL241 Antenna connector. Using the
supplied serial cable, connect the NL241 CS I/O port to the data logger CS I/O port. This cable
supplies communications and power from the data logger to the NL241. Ensure that the device is
powered by inspecting the LED. The LED will be solid red when the device is connecting to or
creating a Wi-Fi network. When the LED starts flashing green, it is ready for Wi-Fi
communications.
8.2.2.2 Configuring the NL241
Connect to the NL241 in
Device Configuration Utility
(see
(p. 20)). On the
NL241 tab, set Bridge Mode to enable.
NOTE:
In bridge mode, the IP address, subnet mask, and IP gateway to be used by the NL241 are
configured in the data logger.
8.2.2.3 Configuring the data logger
1. Connect a serial cable from the computer COM port to the data logger RS-232 port.
2. Open
Device Configuration Utility
. Select the device type of the data logger (CR800,
CR1000, or CR3000), the appropriate Communication Port, and Baud Rate. Click Connect to
connect to the data logger.
