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.
