NL200 Network Link Interface
4. Overview
The NL200 Network Link Interface is a device used to communicate with
Campbell Scientific dataloggers and peripherals using an Ethernet 10/100
Mbps communications link. The NL200 includes a CS I/O port and a RS-232
port for communication. A USB device port is used for configuring the NL200
device.
FIGURE 4-1. NL200
The NL200 can be configured to bridge Ethernet and CS I/O communications
(Bridge Mode Enabled). This mode is used for providing access to the internal
IP functionality of the CR800/850, CR1000, and CR3000 (e.g., web page
access, email, FTP, etc.). Bridge Mode does not utilize PPP. Instead, raw IP
packets are transferred between the Ethernet and CS I/O connections.
FIGURE 4-2. Bridge Mode enabled
With Bridge Mode disabled, the NL200 can be configured to act as a Serial
Server and/or a PakBus Router. The NL200 can act as a Serial Server and
PakBus Router simultaneously. However, each communication port (R2-232
and CS I/O) can only connect to one client (Serial Server or PakBus Router).
Therefore, you can have an RS-232 Serial Server and a CS I/O Serial Server,
an RS-232 Serial Server and a CS I/O PakBus Router, an RS-232 PakBus
Router and a CS I/O Serial Server, or an RS-232 PakBus Router and a CS I/O
