Visão Geral
The RF430 spread spectrum radio includes a USB port to make it easier to connect to newer computers that do not have RS-232 ports. This 100 mW spread spectrum radio/modem operates in the 910 to 918 MHz frequency range, which is used in the US and Canada. The RF430 can transmit data to another RF430 radio, an RF401 radio, or a CR206(X) datalogger.
The RF430 supports point-to-point and point-to-multipoint communications. Although it typically serves as a base station modem/radio, the RF430 can connect to the data logger’s RS-232 port to serve as a field modem (requires a null modem cable and a field power cable).

Descrição Técnica
The RF430 reduces susceptibility to RF interference from other spread spectrum devices by providing user-selectable frequency hopping patterns. Spread spectrum radios spread the normally narrowband information signal over a relatively wide band of frequencies. This process allows communications to be more immune to noise and interference from RF sources such as pagers and cellular phones.
RF430 and RF401 Differences
The RF430 radio is functionally the same as the RF401. The difference between the two is that the RF430 has USB and RS-232 ports, while the RF401 has RS-232 and CS I/O ports.

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). |

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).

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.
-
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.
