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.
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

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.
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.

Yes. The NL120 operates as transparent.
The following are some possible causes:
The NL120 is a communications peripheral only. It does not provide additional analog terminals for a data logger.
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.
No. Only one of those devices can be used at a time with a data logger.
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.
A network camera can be connected directly to a CR1000 or CR3000 via an NL115 or NL120 and a crossover cable. The datalogger can retrieve and store images from the network camera. Then the images can be viewed or retrieved from the datalogger in a variety of ways. These include using LoggerNet, the datalogger’s web server, the datalogger’s FTP client/server, or the datalogger’s email client.
The maximum recommended segment length (length of cable between the NL device and the Ethernet repeater, hub, switch, or router it is connected to) for 10Base-T and 100Base-Tx networks using CAT5e cable is 100 m.
