  • IntroductionThis operator manual serves as the primary document for familiarising users with the parameters ofthe radio modem, its properties, modifications and with the parameters of connecting parts. In order tomaster all the functions of the radio modem and theMORSE system you should refer to other documents.

    In next description is used the notation modem or router instead of radiomodem.

    Introduction

  • 1. Radio modem MR400 (MR300, MR160, MR160P)MR 400, MR300and MR160 are conceptually new radio modems designed for transmitting data in theVHF and UHF bands. The radio modem uses 4-state FSKmodulation providing for a maximum signallingrate of 21.68 kbit/s.

    The radio modem is of modular design with one to four standard RS232 ports (an RS422 or RS485port can be used in place of two of them) available to the user. The configuration can be extended byan Ethernet interface and also by a module with analog and digital inputs/outputs. It is generally man-ufactured with two analog inputs an
