NL120 Ethernet Interface
Services Available

Overview

The NL120 allows the datalogger to communicate over a local network or a dedicated Internet connection via TCP/IP. This small, rugged communication device connects directly to the 40-pin peripheral port on a CR1000 or CR3000 datalogger.

Benefits and Features

  • Compatible with CR1000 and CR3000
  • Connects a data logger to a network
  • Smallest Ethernet module available for the CR1000 and CR3000

Technical Description

The NL120 uses a straight through cable when the cable is run from a hub to the NL120. A 10baseT Ethernet crossover cable is used if the cable is run directly from the computer to the NL120. For cable lengths longer than 9 feet, either a shielded 10baseT Ethernet cable or the 28033 surge protector needs to be used.

The NL120 is set up using the Device Configuration utility (DevConfig). DevConfig is bundled with our PC400, RTDAQ, and LoggerNet software and is available, at no charge, from: www.campbellsci.com/downloads

Additional Compatibility Information

Ethernet Cable

A 10baseT Ethernet straight through cable is used when the cable is run from a hub to the NL120. A 10baseT Ethernet crossover cable is used if the cable is run directly from the computer to the NL120. For cable length longer than 9 ft, the 10baseT Ethernet cable must be shielded or the 28033 surge suppressor must be used.

Data Logger Considerations

The NL120 fastens onto the data logger's 40-pin peripheral port. This means that the NL120 is only compatible with the CR1000 and CR3000. It is NOT compatible with the CR800, CR850, CR200X, CR5000, or CR9000X dataloggers.

Number of FAQs related to NL120: 23

Expand AllCollapse All

  1. Can a Wi-Fi device be plugged into the NL120 so that data logger communication can occur using a Wi-Fi service?

    Yes.

  2. Can the NL120 be used to produce analog voltages?

    The NL120 is a communications peripheral only. It does not provide additional analog terminals for a data logger.

  3. If LoggerNet does not list the NL120, is that OK?

    Yes. The NL120 operates as transparent.

  4. Can the NL120 be repaired? Or does a non-functioning interface need to be replaced?

    Yes, the NL120 can be repaired. Refer to the Repair and Calibration page for the process of returning equipment to Campbell Scientific.

  5. Is there any way to update the firmware of the NL120?

    There is no separate firmware for the NL120. It is built into the main data logger’s operating system.

  6. Can a COM port and an NL120 be used together?

    The PakBus protocol allows multiple simultaneous connections. The PakBus address that LoggerNet uses for itself on one of the PCs needs to be changed, though.

  7. Does an NL120 work with a wireless Ethernet bridge?

    Yes.

  8. Can dual communication modes be run on a single CR1000 using a COM320 and an NL120?

    Yes. By configuring the NL120 as a CSDC device, both the NL120 and COM320 can share the same CS I/O port. The CR1000 and CR3000 are capable of multi-threading, so the NL120 and COM320 can run in parallel. For more information, refer to the NL120 Ethernet Module Instruction Manual.

  9. If a CR1000 or CR3000 is connected to an NL120 and it has been assigned an IP address, can configuration changes be made on the data logger using only the IP connection?

    No. Configurations can be changed, however, via any other mode of communication with the data logger.

  10. Can an NL120 be used to connect multiple CR1000 or CR3000 dataloggers to the Internet?

    No. The NL120 is used for one device only.
