技术说明

NL120 使用10baseT 的以太网直通线缆,从集线器连接到NL120;使用10baseT 的以太网交叉线缆,如果直接从计算机连接到NL120。对于线缆长度大于 9英尺的情形,需要使用带屏蔽的10baseT 的以太网线缆,或28033电涌防护器。

使用设备配置应用软件(DevConfig)来设置NL120。DevConfig捆绑在PC400、LoggerNet和RTDAQ里面。DevConfig 还能免费下载,网址是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.

常见问题解答

NL120: 23

展开全部收起全部

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

  2. Yes. The NL120 operates as transparent.

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

  4. 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.

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

  6. The following are some possible causes:

    • The data logger’s OS needs to be updated.
    • A fault exists in the communications link away from the data logger.
    • The NL120 is not fully plugged in.
    • There are loose or broken cables.
    • For a radio link, the aerial connections and alignment may need adjusting.
    • The NL120 or another device has suffered lightning damage.
