NL201 串口转以太网接口,提供到数据采集器、外设和其它串口设备上的有线以太网网络连接。NL201 支持 PakBus设备等复杂的网络连接。利用独特的技术搭设以太网和CS I/O之间的桥梁,NL201 可提供Campbell Scientific一些数据采集器的IP功能的直接访问。NL201 也可充当TCP 串口服务器,串行端,Modbus TCP/IP, TLS HTTPS代理协议和用户自定义通讯端口。
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.

Notes:
♣The CR300 connects to the NL201 using a 10873 serial that is not supplied with the CR300 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.
Windows USB drivers for the NL200 Series are installed via the Device Configuration Utililty. In the Device Configuration Utility, click on the link "install the device driver" in the main body of text for the NL200 Series.
Note: Drivers must be installed before connecting the NL200 / NL201 to your computer.
Current NL200 / NL201 firmware. Requires the Device Configuration Utility and a USB micro cable.
Note: When updating to OS 10.03 from OS 6 or previous, settings will be reinitialized to factory defaults. When updating to OS 10.03 from OS 7, settings will be retained.
