The following provides an overview of the FreeComm™ system components: 

•  Central Control Unit (CU) 

• 

Valve Controller (VCU) and or Sprinkler Controller (VCU-S)

 

 

The Central Control Unit is comprised of a PC running the FreeComm™ software package on the windows operating system. 

The PC is connected to the main controller via a RS 232 serial port interface. All set-up, network programming, irrigation 

scheduling and operations of the FreeComm™ system are controlled with the Central Control Unit and FreeComm™ 

Software.  

 
 

 

 

The FreeComm™ system use a series of repeaters to relay communication throughout the network to control and 

communicate with all FSC and FVC controllers in real time. The main controller’s 2-way communication can send/receive 

data to/from the valve  or sprinkler enabling unlimited flexible control, reporting and activation of the irrigation system and 
schedule. Actual network communication performance range and controllers varies depending upon the installation and the 

surrounding terrain.
