Establishing Communications with the Control System
Whether uploading programs, troubleshooting, or performing diagnostics,
communication between the control system and a PC must be established.
In electronic terms, a console provides a means of communication between an
operator and the central processing unit of a computer. Crestron Toolbox lets
someone talk to the console of a 3-Series dual bus control system. Crestron Toolbox
allows the operator to establish, monitor, and troubleshoot communications directly
with the control system.
Depending on the control system’s capabilities, the following communication
protocols may be used to communicate with a control system:
• USB communication with a PC via the COMPUTER port on the
control system
• Ethernet communication via CTP (Crestron Terminal Protocol—
reserved port number, default port is 41795)*
• Ethernet communication via Secure CTP over an SSL connection to
port 41797 at the IP address of the processor*
• Telnet (default port is 23)*
• Cresnet for processors operating in the Cresnet slave mode (refer to
“Master-Slave Mode” on page 30)
Whether the intent is to use USB or Ethernet, these methods initially require
connection of the control system to a PC via USB.
Another method for submitting a command to the console is to use the “Console” or
“User Program Commands “symbols in SIMPL Windows in the control system
program. The Console symbol transmits and receives serial data to and from the
control system’s console. The “User Program Commands” symbol allows data typed
at the console to be sent to the program. For more information on the “Console”
symbol, refer to “Console Logic Symbol” on page 14. For more information on the
User Program Commands symbol, refer to “User Program Commands Symbol” on
page 15.
