Connection Methods of Control Systems
You can connect Yealink video conferencing system to the control system via LAN connection or Serial
connection. Select one of the following:
• LAN Connection: Make sure the Yealink video conferencing system and the control system are in the
same network segment. If you use this mode to control the system, TCP protocol is recommended. To
establish a connection, the control system needs to know the IP address and TCP port of the Yealink
video conferencing system.
• Serial Connection: The USB port on the Yealink video conferencing system can be connected to the
serial port on the control system through a USB to RS-232 cable.
