These apparatus allows a point-to-point (or point-to-multipoint) wireless connection between two or more RS232/485 devices, in completely transparent mode. All devices of this series are provided of one optoisolated digital input and one digital output (relay).

The devices of this series are available in the following frequencies:

• VHF 169.400-169.475Mhz (DL169),
• UHF 433.050-434.790MHz (DL433)
• UHF 868-870Mhz (DL868)

and are all characterized by low cost and free use.

Operating on relatively low frequencies, these devices are suitable in all cases where there is a need to overcome obstacles (trees, buildings, etc..) Or, however, where there isn't line of sight between them.

It's also possible to extend the coverage, in compliance of directives, using a third device configured as Digipeater or using a directive antenna Yagi antenna to replace stylus 1/4Lambda or dipole antenna.

The device is characterized by an extremely low power consumption and of a power saving mode that allow the use in battery powered and/or solar powered systems.

The configuration is made through a free software tool running in Windows™ environment.

The device is provided of a RS232 and RS485 interface and a screw terminal block to connect the power supply.

To connect the module with the Picosyst and Netsyst controllers, we suggest to use our adapters and cables code CBL055*000 and CBL057**00.
To connect it to a PC we suggest to use the cable code CBL058*300.

Applications
	The low power consumption and the wide operating temperature, make the product suitable for applications in industrial and automotive fields, and, generally whereas a battery power source is requested, such as the Remote stations (RTUs).
	Telecontrol/Telemetry
