Typically, a central unit together with a radio unit is used in a network as a master station or in locations where Ethernet connectivity is needed. For radio router stations, the central unit is not necessarily required. In these cases, the radio unit can be used alone. This is possible because of the modular structure of the product.

SATELLAR-2DSd includes a radio unit and a central unit, which enables IP connectivity. SATELLAR-2DS can operate either as a transparent radio link, essentially replacing a wire, for classic RS-232, RS-485 or RS-422 based protocols, or can operate as a wireless router in an IP-based network.

SATELLAR-2DSd is equipped with a color display and a keypad, which facilitates programming of the device.

Data security is typically a concern when using radio communication. In SATELLAR, information security was a design priority; 128 bit encryption on the air interface and the use of built in firewall in the central unit ensures privacy both in the radio network and in the wired IP network.

Using SATELLAR-2DSd many network topologies are possible, from point-to-point link to a nationwide chain with multiple branches.
