DTS Series and EUR Series RF Transceiver Module The DTS Series and EUR Series RF transceiver modules combine a low power wireless transceiver with a powerful multipoint-to-multipoint protocol controller to form a transparent wireless communication solution capable of replacing wires in almost any RS-232/422/485 application. The module uses a Digital Transmission System type of spread spectrum. This type of system is allowed to have a higher output power, giving it a range of up to 1 mile (1.6km) without having to hop channels or the expense of a direct sequence (DSSS) system. Interace: The transceiver has a UART serial interface and is designed to create a 0.935 (23.75mm) UART-to-antenna wireless solution. Power: The transceiver is designed for low power applications. Low power modes as well as adjustable transmitter output power allow the designer to optimize the 0.800 (20.32mm) current consumption for the available power supply in the application. Configuration: The transceiver contains several registers that control its configuration and operation. The registers are accessed through the UART and enable a great deal of optimization. 0.110 (2.80mm) Protocol: The transceiver has a robust built-in protocol. A Carrier Sense Multiple Access (CSMA) algorithm makes sure the channel is clear before sending data. Specifications Group ID and addressing enable basic networking. A 16-bit CRC ensures correct Parameter EUR DTS data. Operating Voltage 2.73.6V 2.73.6V Variants: The North American module offers 32 DTS channels in the 902 to TX Supply Current 928MHz band. The Brazilian module removes the channels in the 907 to 915MHz 11dBm 5058mA 6372mA restricted band, leaving 19 DTS channels. The EUR Series offers 2 DTS channels in 0dBm 2635mA 2836mA the 868 to 870MHz band. RX Supply Current 1624mA 1624mA Standby Current 0.85mA 0.85mA Evaluation Module: An evaluation module is available that has the module on a Sleep Current 35A 35A board with an antenna connector and voltage regulator. The North American variant 4 to 4 to TX Output Power has received FCC certification. The Brazil variant has received Anatel certification. 13dBm 11dBm Specific antennas must be used to maintain the certification. This greatly reduces Max.
