NL200/201 Network Link Interface

7.1.4 Connect
You are now ready to connect to your datalogger using the
LoggerNet Connect
screen.
7.2 Bridge Mode
With Bridge Mode Enabled, the device will act as a bridge from Ethernet to
CS I/O. All IP packets that come into the device via Ethernet 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.
7.2.1 Physical Setup
Using the supplied serial cable, connect the NL201’s CS I/O port to the
datalogger’s CS I/O port. Alternatively, power the NL200 or NL201 through
the barrel-connector jack located on the edge of the device. (Note that an
NL200 cannot be powered over CS I/O. An external power adaptor or power
cable is required.) Connect the NL200/201 to your network using an Ethernet
cable, attaching one end of the cable to the NL200/201’s Ethernet port and the
other end to your network. Ensure that the device is powered up by inspecting
the Power LED.
7.2.2 Configuring the NL200/201
Connect to the NL200/201 in
DevConfig
(see Section 6 ,
Configuring the
NL200/201
(p. 10)
). In the NL200/201 tab, set Bridge Mode to enable .
7.2.3 Configuring the Datalogger
x
Connect a serial cable from the PC COM port to the datalogger’s RS-232
port.
x
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.
x
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 NL200/201 is
CS I/O IP Interface #1 (SDC3). 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.
x
Press Apply to save the changes and then close
DevConfig
.
