NL200/201 Network Link Interface
17
7.2.5 Connect
You are now ready to connect to your datalogger using the
LoggerNet Connect
screen.
7.3 TCP Serial Server
The NL200/201 can tunnel RS-232 and CS I/O serial communications over
Ethernet. Any packet sent to the configured Ethernet IP port will have the IP
layer removed, and the serial data is then directed to the serial connection.
7.3.1 Physical Setup
Using the supplied serial cable, connect the NL200/201’s CS I/O port or RS-
232 port to the datalogger’s CS I/O or RS-232 port, respectively. The NL201
will be powered if connected via CS I/O. Alternatively, power the NL200 or
NL201 through the barrel-connector jack located on the edge of the device.
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.
