Codice: RMO436 - 8 CHANNELS 436 MHz 500 mW RADIOMODEM
GENERAL INFORMATIONS
The RMO400 is an high quality UHF Radiomodem in simplex/half duplex mode having a maximum R.F power of 2 W in the 430-450 MHz band. Others band are available and exactly the RMO400-1: 390-410 MHz, RMO400-2:410-430 MHz and RMO400-3: 450-470 MHz. For all available bands the device is compliant with the national directives and rules on the radio spectrum utilisation.
The RMO400SRD device is equal to RMO400 with the R.F. output power reduced to 500 mW. This device is utilisable under the Short Range Device directives applied in each country of the European Community.
The RMO436 is an SRD with an 500 mW R.F. output power working on the Italian PMR Band from 436,000 to 436,100 MHz, containing 8 channels with 12,5 kHz spacing, that the Italian Communications Ministry allows to digital data communications for industrial, commercial and professional uses on payment of a low cost fee. This device is specified for the utilisation in Italy.
For all the above mentioned devices the functionality is fully transparent to the user and the configuration is simply feasible by the related SW utility to install on a personal computer with Windows ‘95→XP operative systems.
All devices are available both as single module with a TTL UART Interface, for a direct connection to a mController board, or as a complete device with the RMO4IN Interface Board for the RS-232/RS-485 interfacing. In the single module version the R/T485 criteria, for the Transmit/Receive commutation of a RS-485 external interface unit, is available on main connector.
For all devices the RMO4EM outdoor mounting kit and the RMO4Y3, three-elements Yagi antenna, are available. Only for SRD apparatus the RMO4Y3 antenna must be used with a 10 m (10.933 yds) of RG-58 coaxial cable.
Specific characteristics:
- Turning ON/OFF by the DTR criteria with less than 100 nA leakage current in DTR OFF condition
- Low power consumption both in RX than TX mode and Power saving utility settable by configuration software
- Broadcasting or addresses management by configuration software or directly by DTE
- Digipeater mode to allow communications between hidden units. In these events the direct communication is generally impossible
- Remote configuration and channel change directly from DTE
- Others advanced configuration utilities as ACK and message resending, Echo, utilisation of received addresses for the answer etc.
All devices are assembled in SMT technology with industrial temperature range components and are specially designed for Low cost Radio Networks where the contemporary necessities of low power consumption, e.g due to a battery or solar cells supply, and an high quality are fundamentals in the device choice.
SW CONFIGURATION INFO:
RMO400.ZIP - Through an RS232 serial interface allows the radiomodem configuration as needed.
RMO400_P.ZIP - Through an RS232 serial interface allows the radiomodem configuration as needed; also allows the choice of parity N, O, E.
FW requires an updated version characterized by word Rel. 1.1 on the product label. Products marked with Rel. 1.1. also use an evolute card interface (see RMO4IN).
