Yealink CT300 Room Device Navigator, Multi-Interface AV Control Processor (1303169)
The CT300 is Yealink's advanced room device navigator, an upgrade from the CT200 that adds higher performance and a substantially expanded set of physical hardware interfaces. Alongside IP-based control of Yealink AVoIP devices, the CT300 provides RS232, RS422/485, GPIO, Relay, and IR ports, extending control to displays, shades, lighting, matrix switchers, and other equipment that doesn't communicate over IP.
As a control processor, the CT300 is specified for rooms with device control needs beyond what a purely IP-based navigator can reach. Two independent network ports separate management traffic from device control, and an Open API extends integration to third-party equipment, with customizable control logic and auto-generated H5 interfaces for streamlined deployment. Before ordering, confirm which devices in the room need serial, relay, GPIO, or IR control versus IP-based control, since that determines whether the CT300's expanded I/O is needed over the CT200.

Certifications and Compatibility
- Yealink AVoIP devices: manages Yealink encoders, decoders, DSPs, sensors, and other networked devices via IP, consistent with the CT200's core function.
- Serial and relay-controlled devices: RS232, RS422/485, GPIO, and Relay ports extend control to displays, shades, lighting, matrix switchers, and other non-IP equipment.
- IR-controlled devices: IR out and IR Learning ports support control of infrared-controlled AV equipment.
- Third-party devices: supported through the CT300's Open API for custom or multi-vendor integrations.
- Compared to CT200: the CT300 adds the expanded physical I/O; both share dual-LAN architecture, Open API, and H5 interface generation.
- Compatibility is limited to Yealink-published and Open API-integrated equipment. Confirm current compatibility against Yealink's documentation for your specific system and firmware.
Design Considerations
- Determine which room devices require serial, relay, GPIO, or IR control before choosing the CT300 over the simpler CT200.
- Plan the physical wiring for RS232, RS422/485, relay, and IR connections to each controlled device during room design.
- Plan the dual-LAN network architecture, keeping management traffic separated from device control.
- Use the auto-generated H5 interface tool to build the room's control UI rather than custom programming.
- For multi-room and multi-site programs, plan a consistent control-processor tier (CT200 or CT300) based on each room's device mix.
VideoConferenceGear.com Assistance
We can help determine whether the CT300's expanded serial, relay, GPIO, and IR interfaces are needed for your room, or whether the simpler CT200 covers your AVoIP-only requirements. We can plan the physical wiring for non-IP devices such as displays, shades, or lighting, advise on the dual-LAN network architecture, and help build the room's control interface using Yealink's H5 auto-generation tool. For multi-room and multi-site programs we can help standardize the control-processor tier and configuration across every space.
Common Questions
How is the CT300 different from the CT200?
The CT300 is an upgraded control processor with higher performance and expanded physical hardware interfaces, including RS232, RS422/485, GPIO, Relay, and IR, in addition to the IP-based AVoIP control both models share.
Why would a room need serial or relay control?
Displays, shades, lighting, matrix switchers, and other equipment that doesn't communicate over IP require serial (RS232/RS422/485), relay, GPIO, or IR control to be integrated into the room's automation.
Does it require custom programming?
No. Like the CT200, it offers customizable control logic with auto-generated H5 interfaces, avoiding traditional programming.
Can it control third-party devices?
Yes, through its Open API, extending control beyond Yealink's own hardware and beyond the devices reachable through its physical ports.
How many RS232 ports does it have?
Six RS232 ports total, per Yealink's published hardware interface specification.
Does it still manage Yealink AVoIP devices over IP?
Yes. It retains the same IP-based device management as the CT200, while adding the physical interfaces for non-IP equipment.
