Radio Remote Operation And Control

The RW3 Three-Radio Remote Set allows an operator to use radios from a remote location up to 5 km away using D-10 or P-274 field wire. The remote operator can select one of the three connected radios to use and speak over the selected radio. 

The RW3 can be used to set up radio communications for open-pit or underground mining applications, rapid high-site installations and general radio remote use scenarios.

The RW3 system consists of two parts:

  • Radio Interface Unit (RIU): Connects to the radios
  • Remote Control Unit (RCU): Used by the remote operator

*The RIU and the RCU must be connected to each other using D-10 or P-274 field wire (not included).

The RW3 also provides an operator CALL function between the Radio Interface Unit and Remote Control Unit

Radio Interface Unit Capabilities

The Radio Interface Unit (RIU) connects to the Radios. It indicates the status of the power supply, radio connection(s) and the integrity of the Field Wire line. The RIU is powered directly from any of the connected radios.

Remote Unit Capabilities

The Remote Control Unit (RCU) provides the interface from which to operate the radio(s). It has a handset connection with volume control which allows normal voice operation. It also has a selector switch to select the radio and mode of operation. The RCU connects to the RIU via a length of Field Wire. The RCU is powered from an external DC power source.

Remote To Local Communication

The RW3 units provide a CALL mechanism between the RIU and RCU units. This allows the RIU to be manned and receive voice calls from the RCU operator. Alternatively, the RIU operator can receive calls from various radios and route them to the RCU unit operator

Built-In Loudspeaker

Both RW3 units are fitted with internal waterproof loadspeakers to alert operators of incoming calls or to monitor radio activity
