Codice: RT400-M-B - 10W UHF RADIOMODEM
GENERAL INFORMATIONS
The RT400-M-B is an high-quality UHF Radiomodem in the 440 - 470 MHz band (other bands on request) characterised by an R.F. Output Power of 2.5 or 10 W in according to the European Communication Standards and the national rules on the radio-frequency spectrum utilisation. The device permits the data communication in transparent mode both in receiving and transmitting conditions through RS-232 or RS-485 serial ports and can send / receive, a digital command or actuation, a feature often required in the remote controls or in the alarm networks.
The device enclosure is an anodised Aluminium box with the supply and service connector, the DE-9 F Serial Port connector, for both RS-232 and RS-485 and the BNC connector (female) for the Antenna. On the box cover, as shown in the above picture, three Leds show the device status and, in particular, the Power ON condition (Green), the ON AIR (Transmitting) condition (Red) and the DATA Flow both in transmitting and receiving mode (Yellow).
The device is completely transparent to the user and may be configured by an external PC using the RT415 configuration software on 8 operating channels that may be selected by a dip-switch bank.
The most important characteristics are the following:
- Power ON controlled by the DTR criterion of the RS-232 serial port. The device is turned on when the DTR is high.
Low power consumption both in receiving and transmission using the Power Saving mode.
- Broadcasting or static / dynamic addresses management by the configuration software or the linked DTE
- Digipeater operating mode to repeat the message in geographically complex networks
- Other sophisticated functions as ACK, message repetition, NAK to DTE if no ACK is received, Echo, addresses reversal for the answer, remote configuration through the communication network and many others functions that may be useful in a communication network
- Protocol compatibility to the RMO 150 Radiomodem to extend an existing network if necessary. This option may be enabled during the configuration process.
The device is assembled in SMT technology with industrial temperature range components and it is specifically designed for Low-Cost data communication networks in which the low power consumption and the high product quality are the most important parameters in the device choice.
The Radiomodem may be used as digipeater in communication networks containing the RT400 transceiver modules. In this case we can supply the communication protocol for the required compatibility.
