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 SWAMP-24X8; refer to the 
Crestron Toolbox help file for details. There are three methods of communication: 
indirect, USB, and TCP/IP.
