Page 1 RT423 User.s Guide & Operating Manual General The RT423 rugged RF transceivers are intended for use in short range wireless data transmission for control & monitoring applications. The RF output power is approx. 250mW. The RT423 works as a pair. It is a Wireless UHF Data Transceiver that will transport RS485 (or RS232C with an external adaptor) data in either direction. The wireless link is Half-Duplex, meaning it can only transmit or receive at a given time. The default data rate is 9600 Baud, although the user may specifically request other baud rates. The Transceivers offer the following features: • A bi-directional data channel with short delay. • Two Alarms and three Telemetry data inputs . optional (if ordered). AVALON RF, INC.

Since the RT423 works as a pair, the pair is shipped with the suffix indicating the operating frequency e.g- RT423-650 indicates the unit is programmed for 650 MHz. If you have ordered multiple sets, please ensure the correct pair is used. The user has to connect the antennas, power & data cables & the link is ready to work. There is no specific setup procedure. 2.3 Electrical Interface. The transmitter has the following interfaces: 2.3.1 Power Input a) The transmitters operate off a 7Vdc-16Vdc unregulated voltage source. a) This input is switched and protected against reverse polarity. b) Typical power input current consumption is 180mA when receivingand 300 mA when transmitting. 2.3.2 Data Input. a) The data input accepts RS485 signals. b...
