Serial Interface - Cisco TelePresence SX20 Quick Set Administrator's Manual

Cisco TelePresence SX20 Quick Set

Introduction

Serial interface

Use one of the USB connectors and an RS-232
adapter for serial communication with SX20. If
the computer does not have a standard serial
connector, you also need a USB to serial adapter
on the computer side.
The serial connection can be used without an
IP-address, DNS, or a network.
Parameters:
• Baud rate: Configurable. Default 38400 bps
• Data bits: 8
• Parity: None
• Stop bit: 1
Video system settings
Serial communication is enabled by default. Use
the following configuration to change the behavior:
SerialPort > Mode
For security reasons, you are asked to sign in
before using the serial interface. Use the following
setting to change the behavior:
SerialPort > LoginRequired
We recommend using the default baud rate or
higher because the video system may give much
feedback. Use the following setting if you want to
adjust the baud rate.
SerialPort > BaudRate
Restart the video system when you have made
changes to the serial port settings.
