RF416 2.4 GHz传播广播电台

Overview

RF416传播广播可用于通用无线数据通信,并支持点对点和点对点数据记录器通信。连接到数据记录器时,它可以用作现场调制解调器/收音机,或者在连接到计算机时用作基站调制解调器/无线电。

这RF416has a frequency range of 2.450 to 2.482 GHz, which is used in many countries worldwide. It can communicate with other RF416 radios, and RF432 radios, as well as the internal radio in CR216(X) dataloggers and AVW216 interfaces.

笔记:这operating frequency band of this radio modem may be shared with other non-licensed services such as cordless telephones and with licensed services including emergency broadcast and air-traffic control.

Detailed Description

传谱收音机通常将正常的窄带信息信号传播到相对较大的频率频段。这使得通信可以高度免疫来自Pagers,Cellular Phone和Multipath等RF来源的噪声和干扰。RF416通过提供用户选择的频率跳跃模式来降低来自其他传播设备的RF干扰的敏感性。

与所有FCC第15部分设备一样,传播光谱无线电不允许对许可无线电通信造成有害干扰,并且必须接受他们收到的任何干扰。大多数坎贝尔科学用户都在干扰不太可能的开放或远程位置操作。如果存在问题,可以使用诸如移动设备,重新定位或使用其他类型的天线或添加RF屏蔽等方法来减少干扰。

为收音机提供动力

At the base station, the RF416 is powered using the 15966 wall charger. At the field site, the RF416 is typically powered by the data logger through the CS I/O port. The #14291 Field Cable is required at the field site for the following situations:

  • 无线电连接到数据记录器的RS-232端口,而不是CS I/O端口
  • 数据记录器于1997年12月之前购买

Antennas

Campbell Scientific offers a variety of antennas for this radio. The 16005 is an omnidirectional 1/2-wave, 0 dBd, whip antenna that connects directly to the radio (no cable required) and can transmit short distances (up to 1 mile). The 17480 dipole antenna includes adhesive for window or wall mounting and a cable for connecting to the radio.

我们更高的增益30411全向和16755 Yagi天线需要电缆将它们连接到无线电。31314电涌保护器可用于易受闪电或静电堆积的收音机,或者在收发器和天线之间测量的电缆长度需要超过3 m(10 ft)时。

其他兼容性信息

通讯

Internal Radio of CR216(X) Dataloggers

RF416传播频谱无线电可以与我们的CR216(X)数据学数据的内部扩散频谱无线电通信。某些RF416设置必须匹配无线电和数据记录器之间通信的CR216(X)设置,以取得成功。这些设备的出厂默认设置可能不匹配;因此,在通信进行之前,可能需要重新配置它们。有关更多信息,请参阅设置RF401到CR206通信的快速参考指南application note (see Documents on the right).

其他传谱收音机

RF416无线电可用于包含RF432和RF415收音机的网络中。当包括RF415收音机的网络中使用RF416无线电时,必须将协议设置为透明。另外,如果RF415和RF416收音机将处于相同的RF接近度,则不要使用RF415净地址使用28、44、52、56或60。RF415无线电的净地址为28、44、52和56,干扰RF416收音机,分别为0、1、2和3的净地址。RF415 60的净地址干扰了所有RF416净地址。

这RF416's 2.4 GHz radio is also a good fit for parallel operation in RF450, 900 MHz networks due to the frequency difference (i.e., 2400 MHz versus 900 MHz).

Campbell Scientific does not recommend using the RF416 in networks containing FGR-115 radios.

透明和PAKBUS协议

Do not mix RF416 radios set to the透明带有RF416或RF432无线电的协议设置为PAKBUS协议中的任何一个,因为这将在没有任何RF通信的情况下产生RF流量。但是收音机与PakBus AwarePakBus Nodesettings can coexist in the same network (i.e., some radios set toPakBus Aware和一些收音机设置为PakBus Node).

Enclosure Considerations

A desiccated, non-condensing environment is required. The 14162 Mounting Kit includes hardware for securing the RF416 to an enclosure backplate (see Ordering Info).

展开全部全部收缩

  1. 是的。这BMP5 Direct SDK只要满足两个条件,就可以与数据记录仪进行通信:

    1. 这communications link between the data logger and the computer is transparent.
    2. 这re are no excessive delays.

  2. 这se radios ship with an SC12 serial cable and a 10873 RS-232 cable.

  3. 这RF416is a 50 mW, 2.45 to 2.46 GHz radio that requires true line of sight. In a dry environment, with absolutely no physical obstruction to impair the line-of-sight path, and with the proper and elevated antennas, the expected range is approximately 5 miles for the RF416.

  4. Antenna selection depends on multiple criteria:

    • 考虑一个特定车站需要与多少电台进行通信。对于仅与一个中继器或基站通信的远程站,定向或Yagi天线可能是一个合适的选择。相反,从许多不同位置接收数据的中继器站可能需要全向天线。
    • Consider if a high-gain antenna is needed to overcome the path between two points. Higher-gain antennas are larger and more expensive.

    为了帮助进行天线选择和现场放置,请考虑租赁和使用演示套件来测试路径质量。Campbell Scientific为RF401,RF430,CR206X和AVW206提供了900 MHz演示套件,以及RF450的演示套件。联系坎贝尔科学以寻求帮助。
