The RF411 has a 920 to 928 MHz frequency range, which is used in Australia and Israel. This 100 mW spread spectrum radio can transmit data to another RF411 radio, an RF431 radio, a CR211(X) datalogger, or an AVW211 interface.

The RF411 supports point-to-point and point-to-multipoint communications. It can serve as a field modem/radio while connected to the datalogger or as a base station modem/radio while connected to a computer. The radio can also serve as a stand-alone RF router/repeater.

The RF401-series and RF430-series spread-spectrum radios are similar. The models in these two series differ in their ports used for connecting to computers/dataloggers and in their frequencies. Refer to the following table for specifics.

Benefits and Features

  • 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
  • RS-232 port for connecting to a computer; CS I/O port for connecting to a datalogger
  • 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 datalogger, as the radios perform "packet address filtering"
  • Built-in setup menus allow access to advanced functionality
  • Designed for use in PakBus networks
