Codice: DL433-IN-B RADIOMODEM 433.050-434.790 MHz
DL868-IN-B is a UHF simplex/half-duplex good quality radiomodem with an output power of 10 mW(erp) with a dedicated lambda/4 antenna, mod. ANT406, or a vertical dipole ANT436DV, operating in the 433.0875-434.7375 MHz band in according to the ERC FREE USE. The radiomodem is enclosed in an extruded aluminium box Reccomendation 70-03. These products are characterised by containing the RS232/RS485 interface and supply unit card RMO148. DL433-IN defines the same device without the box while DL433 is the basic unit without the RS232/485 interface and supply. In
this case a direct TTL interfacing is required and it represents the more favourable solution for a direct microcontroller connection. The following models DL433-IN-B-Y3, DL433-IN-Y3 and DL433-Y3 are the same devices equipped with a three elements Yagi antenna RMOY3. All the Radiomodems are fully transparent to the user and configurable from the PC by dedicated software for the desired functions.
Features:
- Store & Forward mode with 448 Bytes maximum Buffer size
- ON/OFF switching controlled via DTR criteria
- Low power consumption in both RX and TX mode with selectable Power Saving mode from configuration software
- Broadcasting Mode or Address management through configuration software or directly from DTE
- Digital Repeater (digipeater) Mode to permit communications between two or more hidden stations
- Remote programming of the devices and channel selection from DTE
- More sophisticated features as : ACK and repetition of the not received messages, address reversing for the answer, ECHO, NAK to DTE at the end of repetitions, address to DTE and so on.
These devices, assembled with SMT components in the industrial temperature range, is particularly suitable for Low-Cost radio networks in which the battery or solar cells supply require a low power consumption together an high quality product.
