Using the API
The Application Programming Interface (API) is a set of commands for 
advanced users who want to automate a Polycom RealPresence Group system. 
You can use the API by connecting a control system or computer RS-232 serial 
port to a Polycom RealPresence Group system. You can also use Telnet over 
the LAN to use the API with Polycom RealPresence Group systems.
Using the API with an RS-232 Interface
If you use an RS-232 interface to send API commands, you must connect and 
configure the control system or computer and the Polycom RealPresence 
Group system for serial communication. 
Configuring the RS-232 Interface
If you use the API with a serial connection, make sure that the RS-232 
interfaces of the Polycom RealPresence Group system and your computer are 
configured appropriately. 
To access the RS-232 settings on your system, go to Admin Settings > General 
Settings > Serial Port from the web interface.
