Models and Options

The BYOM transmitter line is currently specified around the PTB1312 with its fixed USB-C input, 3840×2160 maximum transmission resolution and configurable button. Buyers who need the action button mapped to a specific room behaviour can request freeze casting or BYOM source switching as the factory setting. Partners integrating the transmitter into their own display or AV platform can discuss hardware and software customization with the manufacturer's engineering team.

Materials and Structure

Aluminum alloy housing

The body is built in aluminum alloy, which keeps the unit rigid while holding weight at 87±2 g.

USB-C input and power

One USB-C input carries the source signal; the device draws 5 V, 4 W.

Embedded Linux platform

Linux 4.19 with 512 MB DDR and 8 GB eMMC runs the transmission stack and the configurable button logic.

Wireless module

Dual-band 2.4/5 GHz Wi-Fi rated to 867 Mbps handles the wireless link to the receiving system.

Applications

  • Corporate meeting rooms
  • Classrooms
  • Training rooms
  • BYOM collaboration spaces
  • Demo rooms and showrooms

Meeting and board rooms

Presenters plug a USB-C laptop in and share content at up to 3840×2160 without cable swapping at the table.

Classrooms and training rooms

Instructors move between rooms with an 87±2 g transmitter and start within ≤15 seconds.

BYOM collaboration spaces

The configurable button can switch the BYOM source, so hybrid rooms hand over cleanly between presenters.

Demo rooms and showrooms

4K output at ≤30 fps supports product demonstrations, video playback and screen sharing for visiting customers.

Customization

tranScreen designs, develops and manufactures its wireless interaction products in-house, which allows standardized units and customized configurations to be produced on the same engineering base. For the PTB1312, the configurable button can be set for freeze casting or BYOM source switching before delivery, and partners working on IFPD integration, display product development or OEM/SDK projects can request hardware and software customization against their platform requirements.

Case Study

10-unit deployment with a Thailand distributor

Application: wireless presentation with one-to-multiple function, transmitting video, audio, touch-back control, camera and microphone signals for meeting rooms, classrooms and exhibition halls.

Result after three years of use: synchronous audio and video casting in one connection, plus multi-screen split display so several sources can appear on screen at the same time. The customer reports that messy cabling and repeated HDMI/audio plugging are eliminated and pre-meeting preparation time is greatly cut.
