Introduction Introduction This operator manual serves as the primary document for familiarising users with the parameters of the radio modem MX160, its properties, modifications and with the parameters of connecting parts. This controller is part of the MORSE system, is fully compatible with other modems, and because it is derived from previously developed types it has similar mechanical parameters to them, as well as all interfaces, the modem part and firmware. For this reason modem MR400 image

Radio modem MX160 1. Radio modem MX160 MX160 is conceptually new radio modems designed for transmitting data in the VHF and UHF bands. The radio modem uses 2-state GMSK modulation providing for a maximum signalling rate of 133 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 . The configuration can be extended by an Ethernet interface and also by a module with analog and digital i

Description of Radiomodem MX160 2. Description of Radiomodem MX160 2.1. Radio part The architecture of MX160 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 micro-controller . The receiving part of the radio

Connectors 3. Connectors 3.1. Antenna The radio modem is fitted with two SMA type connectors for connecting an antenna. The connector labelled Rx is for the receiver , and Tx for the transmitter (up to 25 W). Use the corresponding type of connector with matched impedance as the mate. W e recommend an RG158 cable for the serial lead. Important The radio modem cannot be connected to the power supply without the antenna connected (or corresponding artificial load). Otherwise this could lead to dama

Connectors The T-port module can be positioned in the first or second optional module slot, see section Section 3.1 1, “V iew of Radio Modem” . (Or only in the first slot for MG100 modems.) The second slot is recommended because when using slot 1 you need to take into consideration the fact that it needs disconnecting when the modem is in service mode. For more detailed information see section Section 3.10, “Service Connector” . T-port parameters are set up for communication with attached device
