Overview

RF422 868MHz Spread Spectrum Radio for use in EMEA (-40 to +70C) (Ships as 32160, 16675 & 17648)

The RF422 is an 868 MHz SRD860 radio designed to provide license-free operation for wireless serial communications in Europe. The RF422 transmits data at 10 kbps with a maximum power of 25 mW, and it employs listen-before-talk (LBT) and adaptive-frequency-agility (AFA) to provide a robust link of up to 5 km (line-of-sight). The RF422 supports point-to-point and point-to-multipoint data logger communications and PakBus repeater operation.

The RF422 is part of the RF407 series of radios that includes:

RF407: North America (FCC & IC), 902 to 928 MHz
RF412: Australia (ACMA RCM), 915 to 928 MHz
RF422: Most of Europe and some of Asia (ETSI), 863 to 870 MHz
RF427: Brazil (ANATEL), 905/920 MHz

Technical Description

System Components

An RF422 radio needs to be at both the base station and field site. Each radio requires an antenna that does not exceed 2.1 dBi in gain over the 863 to 870 MHz frequency range, such as the 28767 whip antenna offered by Campbell Scientific.The RF422 has a reverse polarity SMA (RPSMA) connector for attaching the antenna or antenna cable.

Powering the Radio

At the base station, the radio typically uses ac power that is either supplied by the 15966 wall charger or through the PC via the USB port and cable. At the field site, the radio is typically powered by the data logger through the CS I/O port. The 14291 Field Cable can also be used to connect the radio to an appropriate 12 Vdc power supply. This field cable is required when the radio is connected to the data logger’s RS-232 port instead of the CS I/O port.

Benefits

Does not require individual operational license in Europe
Robust serial communication, optimized for PakBus networks
Low power (< 2 mA idle) during periods of inactivity
Supports point-to-point with RF retries and point-to-multipoint operations
Remote diagnostics using PakBus node operations
Operational power can be supplied over USB when attached to PC
