Introduction 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 connecting parts. In order to master all the functions of the radio modem and the MORSE system you should refer to other documents. In next description is used the notation modem or router instead of radiomodem. Fig.
Radio modem MR400 (MR300, MR160, MR160P) 1. Radio modem MR400 (MR300, MR160, MR160P) MR 400, MR300and 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.
Description of Radiomodem Functions 2. Description of Radiomodem Functions 2.1. Radio part 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 operation on any random channel from a given frequency band. The operation of the radio data transceiver module is controlled and diagnosed by the microcontroller.
Description of Radiomodem Functions High-performance radio modems of type P (see serial code) need to be installed in a manner which takes into consideration their high demand for heat dissipation, i.e. the rear side of the modem needs to lie tightly against the mounting plate, as it also serves as a heat sink. Important CAUTION! Danger of explosion upon replacing the incorrect type of battery. Follow the manufacturers instructions for handling used batteries.
Connectors 3. Connectors 3.1. Antenna The cable for connecting the antenna is fitted with an N type connector. Use a connector of the corresponding type and impedance as its mate. We recommend using an RG213 cable for aerial leads up to 25 m in length and a H1000 for longer leads. Important CAUTION. The radio modem cannot be connected to the power supply without the antenna connected (or corresponding artificial load). Otherwise this could lead to damage to the radio part of the modem. 3.2.

Based on standards the receiver terminal RxD of the connected DTE device is connected to the transmitting terminal of the router's SCC port which is also labelled RxD. Similarly the red LED indicating transmission from SCC is labelled RxD. 3.3.

Modem installation 6. Modem installation 6.1. General description of installation Racom routers are built into a robust metal case and are suitable for applications which place them in various environments from air-conditioned offices to heavy industry factories. To a certain extent the method of installation needs to be adapted to this.
Modem installation propagation all influence the type of antenna to be used and where it should be located. Sometimes the appearance of the structure on which the antenna is to be located and the possibility of its damage in publicly accessible places should also be taken into consideration. Generally it can be said that for point-to-point type connections directional antennas are used, and for more remote points and points with a poorer signal multilink directional antennas with greater gain are used.
