Closed captioners can provide captions from inside the conference room, or
from a remote location, via a dial-up connection to the serial port of the VSX
system, as shown in the following diagram.
To supply closed captions via a dial-up connection:
1. Ensure that the computer and the VSX system are configured to use the
same baud rate and parity settings.
2. Go to System > Admin Settings > General Settings > Serial Port and set
the RS-232 Mode to Closed Caption.
3. Establish a dial-up connection between the computer and the VSX
system.
4. On the computer, start the transcription application.
