Introduction

The RFU-433 is an RS-232/485 to 433 MHz radio modem that can be used to convert data from an RS-232/485 device to an RF message that can then be transmitted in transparent mode via the 433 MHz ISM frequency band. The RFU-433 provides a maximum line of sight (LOS) transmission distance of 500 meters (0.5 km) at an RF Baud Rate of 9600 bps. In order to overcome the interference that may be encountered in harsh environments, the RFU-433 allows the RF transmission Baud Rate to be configured to a minimum of 650 bps, enhancing the capability of the modem to resist noise and other interference. Additionally, the RF channels and Group IDs are adjustable, which is helpful when attempting to avoid interference encountered when two RFU-433 networks are adjacent. The 16 RF channels and 8 Group IDs can be configured in order to distinguish and control the different RFU-433 networks. The majority of these configuration parameters can be adjusted using a combination of the Rotary and DIP switches, thereby providing a simple method of maintaining the system if the RFU-433 modem needs to be replaced.
