概述
The RF401 has a 910 to 918 MHz operating frequency range, which is used in the US and Canada. This 100 mW spread-spectrum radio can transmit data to another RF401 radio, an RF430 radio, a CR206(X) datalogger, or an AVW206 vibrating-wire interface.
The RF401 supports point-to-point and point-to-multipoint communications. It can serve as a field modem/radio while connected to the data logger or as a base station modem/radio while connected to a computer. The radio can also serve as a stand-alone RF router/repeater.

详细说明
RF401通过提供用户可选择的跳频图案来减少对来自其他扩频装置的RF干扰的易感性。扩频无线电在相对宽的频带上扩展了正常窄带信息信号。该过程允许通信更加免受噪声和来自RF源的干扰，例如寻呼机和蜂窝电话。

Additional Compatibility Information
Communications
CR206（X）数据转主的内部收音机
The RF401 spread spectrum radio can communicate with the internal spread spectrum radio of our CR206(X) dataloggers. Certain RF401 settings must match the CR206(X) settings for communications between the radio and data logger to be successful. The factory default settings of these devices may not match; therefore, they may need to be reconfigured before communications can take place. For more information, refer to theQuick Reference Guide for Setting Up RF401-to-CR206 Communicationapplication note。
Other Spread-Spectrum Radios
The RF401 can be used in networks containing RF430 and RF400 radios. When RF401 radios are used in networks containing RF400 radios, the Protocol must be set toTransparent。此外，如果RF400和RF401无线电将在相同的RF接近度，请勿为RF400网址使用28,44,52,56或60。RF400无线电，净地址为28,44,52和56干扰RF401无线电，净地址分别为0,1,2和3。RF400净地址60干扰了所有RF401网址。
Campbell Scientific does not recommend using the RF401 in networks containing FGR-115 or RF450 radios.
Transparent and PakBus Protocols
Do not mix RF401 radios set to theTransparentprotocol with RF401 or RF430 radios set to either of the PakBus protocols, since this will produce RF traffic without any RF communications. However radios with the帕克巴斯认识andPakbus节点设置可以在同一网络中共存（即，一些无线电设置为帕克巴斯认识and some radios set toPakbus节点）。
外壳考虑因素
A desiccated, non-condensing environment is required. The 14162 Mounting Kit includes hardware for securing the RF401 to an enclosure backplate (see订购信息）。

对于RF401，没有一个Status表类似于数据记录器的表，但是可以通过终端模式检索一些统计信息。
-
No. The RF401 only transmits at the 100 mW level. If additional power is needed, a directional antenna or a high-gain omnidirectional antenna can be used to increase the effective output of the system.
-
No. For high-frequency data applications, Campbell Scientific recommends using theRF450。
-
The functions of the RF401-series and RF400-series are essentially the same when using thetransparent具有混合阵列数据记录器操作系统的协议。最大的变化是在RF401中添加两个新的协议选项：PB AwareandPB Node。These new protocol options make the radio easier to use in a PakBus network.
-
Campbell Scientific继续为RF401升级提供RF400作为服务。有一个次要升级（PN 18206.) and a major upgrade (PN 18207.）。作为RF401is now retired, however, it may be a better investment to forego the upgrade and purchase a new, higher output, 250 mWRF401A收音机instead. No upgrade service is available to convert an RF400 or RF401 to an RF401A.
-
为了实现原始RF401的相同特性和性能，请将主要的RF400订购到RF401升级服务（PN 18207.）。
-
不，他们不使用相同的空中通信协议。事实上，除非采取额外的步骤，否则这两种型号将彼此干扰。
-
是的。The记录software providesRTMC, an HMI software. The CR10X can be provided with a Modbus communications protocol or PakBus. Both will work very well and are commonly used in SCADA systems. With the Modbus protocol, the CR10X can interface with existing software, and/or existing PLCs.
