    DATA Series Product Overview

    The DATA series product is complete family of value priced radios for private point-multipoint SCADA and other telemetry applications. They operate at the 130-174MHz, 220-222MHz, 330-512MHz frequency bands. The DATA series are available as board level product or as a packaged unit. The board level product allows Lottery Terminal. The packaged unit comes in a small case that is ready to plug in power, an antenna and your terminal device.

    The DATA Series transceivers are designed to help you reduce overall communications cost by providing low power consumption, small size and an inexpensive RF connector.

    All DATA series models are available for private labeling.

    DATA Series Board Level Units

    The DATA series board level unit is a single board measuring approximately 3.5 x 4.75 inches (8.90 x 12.07cm). It comes complete with RF connector and RS-232/485 or TTL interface via a header connector or an edge mounted DB-25. An optional piggyback board is available for RS-485/422 applications.

    The board level unit is fully type accepted and includes its own RF shielding. It may be inserted into your device as simply an internal radio, or it can be tightly integrated within the product.

    The DATA series transceivers operate across the 130-174MHz, 220-222MHz, 330-512MHz, and up to 800-960MHz frequency bands depending on the selected model.
    Q: What are the differences between board level and packaged units?
    The board level unit is a single board (approx. 3.5 x 4.75 inches) designed for internal integration with RF connectors and TTL/RS-232/485 interfaces. The packaged unit is housed in a small extruded case ready for external power, antenna, and terminal device connections.
    Q: What data rates are supported by these radios?
    The digital modems support throughput speeds of 9600bps in a 12.5kHz channel and up to 19.2kbps in a 25kHz channel. The TRX series also supports 4.8/9.6/19.2kbps over-the-air data rates.
    Q: Do these transceivers have regulatory approvals?
    Yes, they are fully type accepted and carry approvals including FCC and IC 400 MHz, ETSI 400 MHz (4800 bps), and SRRC China approval (code: 2012FP6383).
    Q: How can the DATA Series transceivers be configured?
    The radios can be easily configured using a Handheld Terminal (HHT), WDS Configuration Software, or directly through an OEM processor.
    Q: What are the typical applications for these radios?
    They are designed for private point-to-multipoint SCADA, telemetry, lottery terminals, civil air defense alarm systems, and other industrial telemetry integrations.
