Wireless data transmission of serial interfaces via Trusted Wireless (transmission up to several kilometers)

Using the RAD-ISM-2400-DATA-BD wireless module for serial interfaces, it is possible to network several controllers or serial I/Os simply and fast with wireless technology. The proven Trusted Wireless technology ensures the reliable transmission of process data in rough industrial environments.

At a transmission rate of 250 kbps (gross), the control desk control communicates bidirectionally as a master, either directly or via repeaters with up to 254 slaves.


The data is transmitted transparently, so that any protocols, such as Profibus or Modbus, can be passed on. The convenient diagnostics software tool RAD Link can be used to modify wireless parameters of the network devices and to monitor the network for its transmission quality. Another convincing feature is their good diagnostic capabilities.

Your user advantages include

  • International use, even in potentially explosive areas (in acc. with the 94/9/EC (ATEX) and IEC Ex directives)
  • Fast startup
  • Design of complex network structures having up to 254 devices
  • Convenient remote system diagnostics as well as device configuration by means of software
  • Roaming functions
  • High transmission reliability
  • No ongoing costs thanks to the license-free ISM band
  • Suitable for industrial applications at high ranges

Trusted Wireless thus proves itself as an industrial cable replacement for network connections.


Network connections

The slaves are connected directly or via intermediate repeater slave stations. Here, up to 254 repeater slaves can be connected in series to prolong the
wireless path, or to integrate several (repeater) slaves.

Serial peripheral devices can also be connected to the intermediate repeater slave stations, and data can also be recorded and transferred.
