DSSS low power radio transceiver The STD-503 is a 2.4 GHz transceiver enclosed in a small compact shield casing designed for industrial applications. The transceiver uses Direct Sequence Spread Spectrum (DSSS) modulation and true diversity circuit, enabling reliable communications even in the congested 2.4 GHz band. The STD-503 complies with the European EN 300 440, U.S FCC Part 15.247, Canadian ISED RSS-210 and Japanese ARIB STD-T66 standard, making it ready for the global market. The transceiver uses a transparent data interface to enable users to communicate using their own protocols. The module s configuration can be set easily via the UART interface using dedicated commands. *Circuit Design developed an onboard ASIC containing SS correlator (a key part of spread spectrum communication). This ensures long term supply for industrial applications. CE, FCC, ISED and ARIB conformity Uses direct sequence spread spectrum (DSSS) modulation Channel stepping option controlled via CHC pin A true diversity receiver (two built-in receiver circuits) Module settings using dedicated commands Data communication using a transparent interface Low power operation 77 RF channels Communication range 300 m LOS Onboard temperature sensor Applications ・ Industrial telecontrol ・ Telemetry systems Applicable standard EN 300 440 / FCC Part 15.247 / ISED RSS-210 / ARIB STD-T66 Communication method Simplex, Half duplex Emission type Channel spacing Supply voltage Supply current Receiver sensitivity Operating temperature UART 19,200 / 38,400 / 57,600 bps Data Length: 8 bit, Parity: None, Stop Bit: 1, Flow control: None Specifications are subject to change without prior notice Sales Division 7557-1 Hotaka, Azumino, Nagano 399-8303, Japan Tel:+81-(0)263-82-1024 F
