The Data Connect ST202TE
For years, the Bell 202 modem has delivered reliable low speed multi-point communications. Today, this device still enjoys great popularity due to its ability to communicate under adverse conditions. The Bell 202 remains the right choice for telemetry applications, control system, transaction application, and for reliable data deliver over RF or cellular connections.
The Data Connect ST202TE offers a modem implementation of this classic modulation standard. In this design, we have utilized the latest semiconductor technology to guarantee a level of performance and reliability that cannot be matched by older designs.
The industrial rated Data Connect ST202TE is housed in a metal enclosure and is built too meet the most stringent criteria. Temperature ratings, for example, range from -40°C to +85°C. Versatile power supply option will meet most industrial applications.
The ST202TE was designed, however, to allow implementation of a wide variety of OEM applications. Like all Data Connect designs, it is microcontroller based so that it may support custom interfaces and protocols. In addition, the line interface of the ST202TE is capable of supporting, either leased circuits, dial circuits, or short hall twisted pair.
The ST202TE is available in out standalone or rackmount configurations. In addition, this device is available at the board level for OEM applications.
