1. INTRODUCTION
1.1 Aim of Document
The objective of the present document is detail the features, application and operation of the LC-Ind
radio modem.
After introductions about the products and the test and configuration software (MTC Work bench), the
operation of the modems will be described in two distinct parts:
•The ‘Basic operation’ chapter describes the MTC workbench operation
•The ‘Advanced operation’ is more dedicated to the users who want to program and configure the
modem directly. It states all the available commands and registers and gives some operation examples.
A second set of appendix gives additional information about operation, standard and product’s history.
1.2 LC-Ind Modem overview
The LC RF-Modem is a module which is composed of :
•A control / command part including programmable EEPROM(permanent memory)
•A radio part (transmission / reception).
The LC-Ind radio modem is a FSK half-duplex FM radio transceiver (data transmission and reception). The
LC-Ind operates in the 433 MHz frequency band, in compliance with the ETSI 300-220 European regulation.
Operating a 10 mW radiated power, LC-Ind modems can be used without any license.
The LC-Ind modem is based on synthesised frequency (maximum of 10 channels with a 175 KHz spacing)
in order to operate in any condition and in most environments.
Numerous parameters such as transmission rates (serial and radio links), radio channel, data format, etc,
can be programmed via the serial link, using Hayes (or ‘AT’) commands. Those programmed parameters, i.e. the
modem’s configuration, are stored within EEPROM’s registers so that LC-Ind modems are automatically
configured with the lastly saved configuration (channel, data rates, etc) when switched on.
By default, the standard configuration is: 9600 bauds, 8 data bits, 1 stop bit, no parity, channel ‘0’,
transparent mode.
1.3 MTC Software Installation
1. Put Adcon database CD into the PC. The CD is autolaunched and displays a browser on the Adcon database
presentation page.
2. Go to the Adcon database page by clicking either on the “Adcon RF Database” link or on its button.
3. Install the MTC Workbench software by clicking on the “MTC Workbench Installation” link. The software is
automatically installed in “C:\Program File\Adcon\MTC\” (this directory can be changed).
