Description
The Yealink CT300 is an advanced room device navigator built for professional AV-over-IP systems. It gives IT teams and facilities managers centralized control, configuration, and monitoring of in-room devices through dual network ports plus extensive hardware interfaces including RS232, relays, GPIO, and IR. Open APIs support third-party integration and customizable control logic so complex meeting spaces can run with less manual intervention.
Our customers use it when a room needs more than basic network management—think displays, projectors, shades, lighting, or third-party AV gear that still relies on serial or IR. The dual ports keep management traffic separate from device control, which keeps the system more stable and secure.
The Telecom Spot Take
The CT300 is the right fit for our customers who already run Yealink AV ONE gear (or plan to) and also need to control third-party devices in the same room. It is not a video switcher or media encoder—its job is orchestration. If you only need network-based management of Yealink cameras, audio, and AVoIP endpoints, the simpler CT200 is usually enough. When you need physical control ports for relays, serial devices, or IR, the CT300 is the clear step up. Low power draw and flexible mounting (rack or flat) make it practical for both new builds and upgrades.
Key Features
- Extensive hardware control ports — Six RS232 ports (two bidirectional), two RS422/485, four normally-open relays (30 VDC / 2 A), four GPIO, two IR outputs, and an IR learning port let you drive displays, projectors, screens, shades, and other legacy gear without extra controllers.
- Dual network ports — Separate management traffic from device-control traffic for cleaner, more secure network performance in professional AV environments.
- Open API for third-party integration — Custom control logic and inter-device linkage so the CT300 works with both Yealink devices and external systems.
- Flexible power and mounting — Runs on PoE (802.3af) or the included 12 V / 2 A adapter. Installs in a rack (half-rack width, 1U) or on a flat surface/wall with the included kit.
- Low power consumption — Average 2.5 W, peak 3.3 W, standby 1.7 W keeps heat and energy use minimal.
- Broad Yealink device support — Manages cameras (UVC86, SmartVision 80), audio (CM20/CM50, CS10 series, MSpeaker), processors (AVHub, AVBridge, AP08), AVoIP (EN300/DE300), touch panels, and more when used in AV ONE deployments.
