MDS Master Station Series Product Overview
The GE MDS Redundant, Full-Duplex Master Station Series offers the ultimate in reliability and simplicity for ease of configuration and operation.
The GE MDS Master Station Series is the price/performance leader in licensed microwave radio in the 330-512 MHz frequency range. It gives increased throughput, longer-range alternatives for our customers’ Multiple Address Systems needs. Transparent and direct asynchronous communication offer real-time communication. No extra software or programming is needed to implement communications from standard asynchronous protocols.
The GE MDS Master Station Series may operate as a full duplex, half-duplex or simplex radio and is configurable as a redundant master station or remote radio. When operating as a master station it controls all network parameters of the remotes. The MDS 4790 and MDS 4710 remote transceivers together offer a new level of ease of integration and performance reliability for our customers’ data network systems.
Why Consider a GE MDS Master Station Series Solution?
High system performance and data integrity! Through robust construction and digital signal processing technology (DSP) we offer up to 19.2 kbps data throughput.
Reliability! For mission critical needs, system back-up capability is built-in.
Rapid Installation! Quick return on investment due to ease of wireless installation. This licensed radio offers the ability to communicate with any asynchronous protocol without extra software or extra programming.
Performance under the most adverse conditions! Exceptional design provides excellent performance in the face of interference or difficult signal paths. Will accept external bypass high performance duplexers or receive filters.
Network Wide Diagnostics! InSite Network Management software simplifies tasks and reduces the cost of managing the network infrastructure. Provides a non-intrusive means of maintenance and link monitoring.
Features
- Digital Signal Processing (DSP) Engine
- Software Configurable Modems
- Modular Design with Swappable Power Supply
