概览

RF430 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。RF430 射频电台的操作频段是910 到 918 MHz,适用于美国和加拿大。RF430的功率只有100 mW,可发送数据到另一个RF430 电台、RF401 电台或CR206(X) 数据采集器。

RF430 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,RF430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
  • Transmits up to one mile with omnidirectional antenna; up to 10 miles with higher gain directional antennas at ideal conditions
  • Individual FCC license not required
  • Optional extended temperature testing
  • Settings stored in non-volatile memory
  • Designed for use in PakBus networks
  • Frequency-hops over 25 channels avoids interference from other spread spectrum radios
  • 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,RF430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。

RF430 和 RF401的区别
RF430 电台在功能上与RF401一样。两者之间的差别在于,RF430 具有USB 和 RS-232端口,而RF401 具有RS-232 和 CS I/O端口。

产品规格

Operating Frequency 910 to 918 MHz
Type Frequency Hopping Spread Spectrum (FHSS) Transceiver
USB Baud Rate 38.4k, 19.2k, 9600, 4800, or 1200 bps

If an RF430 radio has an operating system prior to OS2, its USB port will only communicate at 38.4 kbps. Therefore, the operating system of an RF430 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).
RS-232 Data Rate 38.4k, 19.2k, 9600, 4800, or 1200 bps
Channel Capacity 65,000 Network Identifiers share 25 hop channels.
Frequency Hopping Patterns Six different selectable patterns
Receiver Sensitivity -110 dBm at 10-4 bit error rate (Campbell Scientific protocols will issue retries wherever a bit error occurs.)
Interference Rejection 70 dB at pager and cellular phone frequencies
Transmitter Power Output 100 mW (nominal)
Antenna Connector Reverse polarity SMA
FCC ID OUR9XTREAM
Power 9 to 16 Vdc
LEDs Power on, TX, RX, diagnostics
RS-232 Connector 9-pin “D” female (4 wire: Tx, Rx, CTS, GND)
Power Connector Barrel plug, center positive 12 V (used to connect the 14291 Field Power Cable)
Standard Operating Temperature Range -25° to +50°C
Extended Operating Temperature Range -55° to +85°C

The push button that allows you to check/edit programmable settings while the radio is connected to a computer may not operate at temperatures colder than -25°C.

Weight 227 g (8 oz)

Average Current Drain

Standby < 1 mA (power-saving options used)
Receiving 26 mA

Additional Compatibility Information

Communications

Other Spread-Spectrum Radios

The RF430 radios can be used in networks containing RF401 and RF400 radios. When RF430 radios are used in networks containing RF400 radios, the Protocol must be set to Transparent. Also, if RF400 and RF430 radios will be in the same RF proximity, do not use 28, 44, 52, 56, or 60 for the RF400 Net Address. RF400 radios with Net Addresses of 28, 44, 52, and 56 interfere with RF430 radios with Net Addresses of 0, 1, 2, and 3, respectively. The RF400 Net Address of 60 interferes with all RF430 Net Addresses.

Campbell Scientific does not recommend using the RF430 in networks containing FGR-115 or RF450 radios.

Transparent and PakBus Protocols

Do not mix RF430 radios set to the Transparent protocol with RF430 or RF401 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 RF430 radio has an operating system prior to OS2, its USB port will only communicate at 38.4 kbps. Therefore, the operating system of an RF430 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).

常见问题解答

  1. Download the RF430 driver from the Downloads page. 

  2. In theory, a single RF430 can communicate with 4,000 CR206X dataloggers, as this is the maximum number of unique PakBus addresses available for use in a single RF network. The practical limit depends on how frequently data is retrieved from all the remote sites.

  3. There is a good chance that they would. However, the RF401A radios have been designed to work with Campbell Scientific data loggers. There are more generic spread-spectrum radios (off the shelf) that are designed to work in this type of configuration.

  4. 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.
