Page 3: Introduction
This operator manual serves as the primary document for familiarising users with the parameters of the radio modem, its properties, modifications and with the parameters of interfaces. In order to master all the functions of the radio modem and the MORSE system you should refer to other documents. Figure 1. Radio modem MR400 (MR300, MR160) -

1. Radio Modem MR400 (MR300, MR160 MR 400, MR300 and MR160 are conceptually new radio modems designed for transmitting data in the VHF and UHF bands. The radio modem uses 4-state FSK modulation providing for a maximum signalling rate of 21.68 kbit/s. The radio modem is of modular design with one to four standard RS232 ports (an RS422 or RS485 port can be used in place of two of them) available to the user. -

2. Description of Functions Radio Part MR400 The architecture of MR400 (MR300, MR160) radio modems resolves most of the requirements placed on a top quality user friendly radio modem with a very short switching time between receiving and transmitting. Frequency synthesis enables software selection of an arbitrary channel from the given frequency range. The operation of the radio part is controlled and diagnosed by the microcontroller. -

3. MR 400 Connectors Antenna The antenna connector is of the N type, female, impedance 50 Ohm. The antenna cable must be fitted with an appropriate mate. We recommend using the RG213 50 Ohm cable. The H1000 cable should be used when the length of the antenna feeder exceeds 25 m. -
Page 7: Ethernet
Ethernet Connector RJ-45 for Ethernet 10BaseT and 100BaseT corresponds to the EIA TIA T568B standard. Informative LED diodes indicate: Tx – output from CU Rx – input to CU 100 – if lit the 100BaseT LINK network is indicated – indicates correctly connected F.D. link – indicates full duplex operation. A “straight” cable is needed for connecting to the Ethernet network via the hub (repeater) or switch-hub (router). -

passed to this terminal about the method of supply; level TTL0 – 230 V AC supply, TTL1 – battery supply. If the radio modem is supplied in another manner the method of supply is deduced according to the voltage (the value from which the supply is considered as supply from a battery can be set in SW). -
