    1.0 GENERAL 1.1 Introduction This guide presents installation and operating instructions for the MDS 4710A/9710A (400/900 MHz) digital radio transceivers. These transceivers (Figure 1) are data telemetry radios designed to operate in a point-to-multipoint environment, such as electric utility Supervisory Control and Data Acquisition (SCADA) and distribution automation, lottery systems, gas field automation, water and wastewater SCADA, and on-line transaction processing applications.

    NOTE: 4710A/9710A remotes do not support full-duplex operation. Switched Carrier operation is a half-duplex mode of operation where the master station transmitter is keyed to send data and unkeyed to receive. Single Frequency (Simplex) Operation Single frequency operation (also known as simplex) is a special case of switched carrier operation.
