Using the API
The Application Programming Interface (API) is a set of commands for
advanced users who want to automate a Polycom HDX system. You can use
the API by connecting a control system or computer RS-232 serial port to the
Polycom HDX system. Or, you can use Telnet over the LAN to use the API.
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 HDX 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 HDX system and your computer are configured
appropriately.
To access the RS-232 settings on your system, select System > Admin Settings
> General Settings > Serial Port.
