RF416 2.4 GHz Spread-Spectrum Radio

Überblick

RF401: -Dieses Produkt ist nicht mehr erhältlich und wird vom  RF401A ersetzt. einige Zubehör- oder Ersatzteile können aber noch erhältlich sein.

Das RF416 hat einen Frequenzbereich von 2,45 bis 2,46 GHz, der in vielen Ländern der Welt verwendet wird. Dieses 50 mW Funkmodem kann Daten zu einem anderen RF416, einem RF432 Funkmodem, einem CR216(X) Datenlogger oder einem AVW216 senden und empfangen.

Das RF416 unterstützt Punkt-zu-Punkt und Punkt-zu-Mehrpunkt Kommunikation. Es kann als Feldmodem eingesetzt werden wenn es mit einem Logger verbunden ist oder als Basisstation wenn es an einem PC angeschlossen ist. Es kann auch als unabhängiger Funkrouter oder Repeater verwendet werden.

Aufgrund von Gesetzesänderungen in der EU dürfen wir dieses Produkt nach dem 1.1.2015 nicht mehr verkaufen, Ausnahme wenn eine schriftiche Erklärung vorliegt, dass der Kunde es außerhalb von Europa oder als Ersatzteil in einem existierenden Netzwerk einsetzen will.

Technische Beschreibung

The RF416 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.

Additional Compatibility Information

Communications

Internal Radio of CR216(X) Dataloggers

The RF416 spread spectrum radio can communicate with the internal spread spectrum radio of our CR216(X) dataloggers. Certain RF416 settings must match the CR216(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 the Quick Reference Guide for Setting Up RF401-to-CR206 Communication application note (see Documents on the right).

Other Spread-Spectrum Radios

RF416 radios can be used in networks containing RF432 and RF415 radios. When RF416 radios are used in networks that include RF415 radios, the Protocol must be set to Transparent. Also, If RF415 and RF416 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 RF416 radios with Net Addresses of 0, 1, 2, and 3, respectively. The RF415 Net Address of 60 interferes with all RF416 Net Addresses.

The 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.

Transparent and PakBus Protocols

Do not mix RF416 radios set to the Transparent protocol with RF416 or RF432 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).

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).

  1. Yes. The BMP5 Direct SDK can communicate with the datalogger as long as two conditions are met:

    1. The communications link between the datalogger and the computer is transparent.
    2. There are no excessive delays.

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

  3. The RF416 is 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: 

    • 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.
