InfiNET EX™ Gateway  Crestron CEN-RFGW-EX 
Uploading and Upgrading 
Crestron recommends using the latest programming software and that 
each device contains the latest firmware to take advantage of the most 
recently released features. However, before attempting to upload or 
upgrade it is necessary to establish communication. Once communication 
has been established, files (for example, programs or firmware) can be 
transferred to the control system (and/or device). Finally, program checks 
can be performed (such as changing the device ID or creating an IP table) 
to ensure proper functioning. 
Establishing Communication 
Use Crestron Toolbox for communicating with the CEN-RFGW-EX; 
refer to the Crestron Toolbox help file for details. There are two methods 
of communication.
