Campbell Scientific’s NL115 enables 10baseT Ethernet communications and stores data on a removable CompactFlash® card. This small, rugged communication device connects to the 40-pin peripheral port on a CR1000 or CR3000 datalogger.
The NL115 allows the datalogger to communicate over a local network or a dedicated Internet connection via TCP/IP. A 10baseT Ethernet straight through cable is used when the cable is run from a hub to the NL115. A 10baseT Ethernet crossover cable is used if the cable is run directly from the computer to the NL115.
The NL115/CF card combination can be used to expand the datalogger's memory, transport data/programs from the field site(s) to the office, and upload power up functions. One Type I or Type II CompactFlash (CF) card fits into the NL115’s card slot.
Only industrial-grade CF cards should be used with our products. Although consumer-grade cards cost less than industrial-grade cards, the consumer-grade cards are more susceptible to failure resulting in both the loss of the card and its stored data. Industrial-grade cards also function over wider temperature ranges and have longer life spans than consumer-grade cards.
Data stored on the card can be retrieved either by removing the card and carrying it to a computer or through a communications link with the datalogger. The computer can read the CF card either with the computer’s PCMCIA slot and the CF1 adapter or the computer’s USB port and the 17752 Reader/Writer.
CardConvert is used to convert and save binary data from a CompactFlash® card. CardConvert is included in our PC200W, PC400, LoggerNet, and RTDAQ datalogger support software.

Campbell Scientific offers and recommends several CF cards (see Ordering tab). These cards have passed Campbell Scientific's ESD testing and operate properly with our data loggers.
Only industrial-grade CF card should be used with our products. Although consumer-grade cards cost less than industrial-grade cards, the consumer-grade cards are more susceptible to failure resulting in both the loss of the card and its stored data. Industrial-grade cards also function over wider temperature ranges and have longer life spans than consumer-grade cards.
The NL115 is set up using the Device Configuration utility (DevConfig). The NL115 requires LoggerNet 3.2 or later, PC400 1.3 or later, and DevConfig 1.5 or later.
The NL115 fastens onto the data logger's 40-pin peripheral port. This means that the NL115 is only compatible with the CR1000 and CR3000. It is NOT compatible with the CR800, CR850, CR200X, CR5000, or CR9000X dataloggers.
To read cards with more than 2 GB of storage, the data logger operating system must be OS 25 or later.

The file on the card is open until the program is stopped or the button on the device is pressed.
For detailed information, review the information in the “CF Card Information” application note.
The best practice is to format the CF card, not using “Quick Format” on a PC, before inserting it into a device.
When the CardOut() instruction or the TableFile() with TFOption 64 instruction is used, the data table is saved to both the data logger’s internal memory and the card.
Review the CRBasic Editor Help for information on the TableFile() instruction.
Using the FileControl() instruction, the .dat files can be retrieved directly from the memory card. When data is collected by the standard method (not as downloaded files, but as streamed data) with a GetData() or similar instruction, the memory card is automatically used as a source of records to be returned when the internal CPU table no longer contains the oldest data. These records can be retrieved simply by using their record numbers.
No. Only a program change could cause this. To save data to a CFM100 or an NL115, a CardOut() or TableFile() instruction must be present in at least one data table.
If the CardOut() or TableFile() instructions are configured as fill and stop, the data logger will stop writing data to the CompactFlash cards after they are full.
The available storage can be augmented by adding an NL115 or a CFM100 with an industrial-grade CompactFlash memory card. An SC115 CS I/O-to-USB Flash Memory Drive can also be used.
