Overview

RF432 2.4GHz Spread Spectrum Radio (-25 to +50C) w/USB & RS-232

The RF432 spread-spectrum radio includes a USB port to make it easier to connect to newer computers that do not have RS-232 ports. This 50 mW spread-spectrum radio/modem operates in the 2.450 to 2.460 GHz frequency range, which is used worldwide. The RF432 can transmit data to another RF432 radio, an RF416 radio, or a CR216(X) datalogger.

The RF432 supports point-to-point and point-to-multipoint communications. Although it typically serves as a base station modem/radio, the RF432 can connect to the data logger RS-232 port to serve as a field modem (requires a null modem cable and a field power cable).

With USB and
RS-232

Technical Description

The RF432 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.

RF432 and RF416 Differences

The RF432 radio is functionally the same as the RF416. The difference between the two is that the RF432 has USB and RS-232 ports, while the RF416 has RS-232 and CS I/O ports.

Benefits

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

Specifications

Operating Frequency: 2.450 to 2.482 GHz
Radio Type: Frequency Hopping Spread Spectrum (FHSS) Transceiver
USB Baud Rate: 38.4 k, 19.2 k, 9600, 4800, or 1200 bps

(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. For example, CR200(X), CR510, CR10X.)
RS-232 Baud Rate: 38.4k, 19.2k, 9600, 4800, or 1200 bps
