概览
RF432 射频电台包含一个USB 端口，这让它更容易连接到新一些的没有RS-232端口的计算机。RF432 射频电台的操作频段是2.450 到 2.460 MHz，适用于世界上的很多国家。RF432的功率只有50 mW，可发送数据到另一个RF432 电台、RF416 电台或CR216(X) 数据采集器。
RF432 支持 点-点 或 点-多点 的通讯方式。尽管它通常用作基站modem/电台，RF432也能连接到数据采集器的RS-232 端口，作为野外 modem使用（需要一根空modem线缆和一根野外电源线）。
优势与特点
- USB port for connecting to a computer; RS-232 port for connecting to a data logger
- Rugged, low-cost transceivers
- Can be used in the field as a transceiver or in the office as the base station
- Transmits up to one mile with omnidirectional antenna; up to 10 miles with higher gain directional antennas at ideal conditions
- Settings stored in non-volatile memory
- Designed for use in PakBus networks
- Frequency-hops over 25 channels avoids interference from other spread spectrum radios
- Optional extended temperature testing
- Faster communication due to elimination of some small "link state packets"
- Ability to have stand-alone RF router/repeaters (up to 8 repeaters)
- Greater immunity to interference and RF collisions by using RF retries
- Reduced power consumption by the data logger, as the radios perform "packet address filtering"
- Built-in setup menus allow access to advanced functionality

技术说明
通过提供用户可选择的频段跳频模式，RF432减小了来自其它射频设备的无线电干扰的敏感性。射频电台在相对宽波段的频带上，传播正常的窄波段信息讯号。这种处理方法使得通讯噪声更低，和更不易受无线电源的干扰，例如寻呼机和蜂窝电话。
RF432 和 RF416的区别
RF432 电台在功能上与RF416一样。两者之间的差别在于，RF432 具有USB 和 RS-232端口，而RF416 具有RS-232 和 CS I/O端口。

Additional Compatibility Information
Communications
Internal Radio of CR216(X) Dataloggers
The RF432 spread spectrum radio can communicate with the internal spread spectrum radio of our CR216(X) dataloggers.
Other Spread-Spectrum Radios
The RF432 can be used in networks containing RF416 and RF415 radios. When RF432 radios are used in networks containing RF415 radios, the Protocol must be set to Transparent. Also, if RF415 and RF432 radios will be in the same RF proximity, do not use 28, 44, 52, 56, or 60 for the RF415 Net Address. RF415 radios with Net Addresses of 28, 44, 52, and 56 interfere with RF432 radios with Net Addresses of 0, 1, 2, and 3, respectively. The RF415 Net Address of 60 interferes with all RF432 Net Addresses.
The RF432'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 RF432 in networks containing FGR-115 radios.
Transparent and PakBus Protocols
Do not mix RF432 radios set to the Transparent protocol with RF432 or RF416 radios set to either of the PakBus protocols, since this will produce RF traffic without any RF communications. However radios with the PakBus Aware and PakBus Node settings can coexist in the same network (i.e., some radios set to PakBus Aware and some radios set to PakBus Node).
Data Logger Considerations
If an RF432 radio has an operating system prior to OS2, its USB port will only communicate at 38.4 kbps. Therefore, the operating system of an RF432 radio may need to be updated to a newer version if the network will contain data loggers that do not support 38.4 kbps (e.g., CR200(X), CR510, CR10X).

Antenna selection depends on multiple criteria:
- Consider how many stations a particular station needs to communicate with. For remote stations in communication with only one repeater or base station, a directional or Yagi antenna may be an appropriate choice. In contrast, repeater stations that receive data from many different locations will probably require an omnidirectional antenna.
- Consider if a high-gain antenna is needed to overcome the path between two points. Higher-gain antennas are larger and more expensive.
To help with antenna selection and site placement, consider renting and using a demo kit to test the pathway quality. Campbell Scientific offers a 900 MHz demo kit for the RF401, RF430, CR206X, and AVW206, as well as a demo kit for the RF450. Contact Campbell Scientific for assistance.
