Overview
The NL201 is a serial-to-Ethernet interface that provides a wired Ethernet network connection to data loggers, peripherals, and other serial devices. The NL201 supports sophisticated networking capabilities for PakBus devices and networks. Using a unique technique to bridge the Ethernet and CS I/O ports, the NL201 can provide direct access to the integrated IP functionality of some Campbell Scientific data loggers. The NL201 can also act as a standard TCP serial server, serial client, Modbus TCP/IP gateway, and TLS proxy server for HTTPS and user-defined-port communication.
Key Advantages
Very low power
Technical Description
The NL201 connects to an Ethernet network using a 10Base-T/100Base-TX, full or half duplex, Ethernet interface. It has CS I/O and RS-232 ports for connecting a Campbell Scientific data logger, peripheral, Modbus RTU, or other serial-based device. A USB micro B connection is provided for on-site configuration using Device Configuration Utility software.
The NL201 can act as a PakBus router, TCP serial server, TCP serial client, Modbus TCP/IP gateway, and TLS proxy server for HTTPS and user-defined-port communications.
The NL201 also provides a unique mode that bridges the Ethernet and CS I/O ports. This allows access to the internal IP functionality of the CR6, CR800, CR850, CR1000, and CR3000 (for example, web page access, email, FTP). Adding an NL201 configured in this manner to a CR800 is analogous to adding an NL121 to a CR1000’s peripheral port. Adding an NL201 configured in this manner to a CR800 is analogous to adding an NL120 to a CR1000’s peripheral port.

Common Accessories
(8)15966
Wall Charger with Barrel Plug
The 15966 is often used when the NL201 is in an office next to a computer. It is an ac/dc transformer that accepts inputs from 90 to 260 Vac @ 47 to 63 Hz, and then outputs 12 Vdc @ 880 mA. The 15966 is fitted with a cable and barrel plug to connect the transformer to the NL201; cable length is 6 ft.
Orderable14291
Field Power Cable, 12 Vdc Plug to Pigtail
The 14291 is a field power cable that allows the NL201 to be powered from a suitable 12 Vdc battery. It terminates in a barrel plug on one end for connection to the NL201 and two pigtails for connection to the 12V and GND terminals on a power supply. The cable has a 2 foot length.

Notes:
♣The CR300, CR310, and CR350 connect to the NL201 using a 10873 serial that is not supplied with the data logger or the NL201. The CR300-series dataloggers are not compatible with the bridge mode functionality in the NL201 interface.
* Although compatible, the CR9000X does not need an Ethernet interface because it has an on-board Ethernet port.
** It is possible to use an NL201 to connect to a mixed-array data logger (e.g., CR10, CR10X, CR23X, 21X, CR7) by using an SC32B between the data logger's CS I/O port and the NL201's RS-232 port.
