Purpose

The radio “MOST” (radio modem) is designed for digital data exchange over a radio channel in a simplex and (or) half-duplex mode.

Fields of application

• exchange of data packages;
• telemetry with a bidirectional data flow;
• signaling systems;
• remote control and control of distant objects;
• control systems for production, transport.

The radio is connected to peripherals via a standard serial port RS232. Power cables and antennas are connected to jacks on the modem rear panel. A metal housing ensures a high level of protection against external disturbance. Transceiver modules and power modules are rigidly attached to one another.

The radio (radio modem) has a wide range of service functions, which increase its performance characteristics; there is a possibility of measuring and outputting data on the level of an input signal, WSVR of an antenna-feeder device, supply voltage, temperature inside the transmitter housing etc.

• car version — only a transceiver, which is powered from a DC 10,8-15,6 V network;
• locomotive version — transceiver with the pulse power supply BP from a DC 41-55V network;
• fixed version — transceiver with a linear power supply BPS from the AC 187-242V network;
• 1 fixed version — transceiver with a BPS power supply and RS232/RS422 interface converter. The interface converter allows standard operation of the radio, when it is at a distance up to 1,5km from the digital device.
