CT300
Yealink CT300 Advanced Room Device Navigator
A room device navigator for AV-over-IP and smart room systems, the Yealink CT300 brings serial, relay, GPIO and infrared control into one unit. It offers two network ports, RS232 and RS422/485 serial interfaces, four relays and an open API for third-party integration. It suits boardrooms, training rooms and control rooms across Qatar where several devices need one controller. Request a quote from SmartRooms Qatar to confirm the interfaces and mounting for your room.
What the CT300 does inside a room
The CT300 is a room device navigator, a controller that sits within an AV system and sends commands to the equipment around it. Instead of fitting a separate controller for each function, one CT300 can handle serial commands, relay closures, digital inputs and infrared signals. That is useful in a room with a display, a conferencing codec, a projector screen and lighting, where every item needs to respond to a single control point.
Two network ports and separate management
The unit provides two network ports, one PoE and one RJ45. Keeping management traffic apart from device control traffic helps integrators protect control commands from configuration work, and it gives IT teams a clearer view of what is connected to each network. A dedicated MGMT port is also fitted, and a 1.0 m USB 3.0 Type-C to Type-A cable is supplied for that connection.
Control interfaces for mixed equipment
- Serial: RS232 and RS422/485 ports, with rates from 300 to 11520 baud
- Relays: four normally open relays rated 30VDC, 2A
- GPIO: four in/out channels that can serve as analog inputs (12-bit, 0 to 24VDC), digital inputs or digital outputs at 3.3 V, 3.3 mA
- Infrared: two IR outputs with a 34 to 42 kHz carrier, plus an IR learning port that captures codes below 4 m from the front panel
- Open API: for third-party integration and customised control logic
Where it fits in Qatar
In a boardroom in West Bay or Lusail, a CT300 mounted near the table can switch the display and the screen, trigger a lighting scene through a relay, and send infrared commands to an older projector. For a private school in Al Wakrah fitting out new classrooms, one unit per room keeps the controls consistent across the building. In a university control room in Education City, a rack-mounted CT300 can bring several serial-controlled switchers and AV devices under one management point.
Planning the installation
The CT300 measures 216 × 160 × 36.7 mm and weighs 1.07 kg. It installs on a rack or a flat surface, and the mounting kit includes mounting ears, a rack connection piece and screws. The rated operating range is -10°C to +45°C at 10% to 95% humidity. Summer temperatures outside buildings in Qatar can exceed 45°C, so place the unit in an air-conditioned room or a ventilated cabinet, and confirm the enclosure with the SmartRooms Qatar team before work starts. Power draw is 2.5 W average, 3.3 W peak and 1.7 W standby, supplied by the 12V 2A adapter in the box. Map the serial, relay and IR cable runs on the room layout before pulling cable.
Request a quote from SmartRooms Qatar with your room layout and the list of devices you need to control. Our team will confirm the interfaces, cabling and mounting you need. Quotations are usually provided within one working day, and we deliver to all eight municipalities of Qatar.
