RS-232 Mode —
The RS-232 port on the Polycom HDX system supports two modes: Control
and Pass-Thru.
In Control Mode, a device (for example, a computer) connected to the RS-232
port can control the system using the API.
In Pass-Thru Mode, the operational modes of both devices' RS-232 ports
depend on the port configuration of each device.
After you have verified that the Polycom HDX system and your computer are
both configured appropriately, set up both devices as follows:
1. Power off the computer and the Polycom HDX system.
2. Use an RS-232 cable to connect the control system or computer RS-232
port to an RS-232 port on the Polycom HDX system as shown in the
following illustration. This connection may require the null modem
adapter 1517-21577-001 on page 2-41.
