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 a Polycom HDX 9000, Polycom HDX 8000, Polycom HDX 7000, or Polycom HDX 4000 series
system. You can also use Telnet over the LAN to use the API with Polycom HDX 9000, Polycom HDX 8000,
Polycom HDX 7000, Polycom HDX 6000, and Polycom HDX 4000 series 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 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, go to Admin Settings > General Settings > Serial Port
from the web interface.

The RS-232 port on the Polycom HDX system supports the following modes:
● Off — Disables the serial port.
● Pass Thru — Passes data to an RS-232 device, such as a serial printer or certain types of medical
devices, connected to the serial port of the far-site system. Only available in point-to-point calls. In
this mode, he operational modes of both devices' RS-232 ports depend on the port configuration of
each device.
