Control module VISION TC3-CTL/2 — 8-button IR learning panel with RS-232 support

VISION TC3-CTL/2 is a compact control module with an 8-button interface, IR learning capability and RS-232 support. Designed for integration into audiovisual and building automation systems, it provides manual control and programmable infrared command storage alongside serial communication for system interoperability. The panel is intended for rack-mounted or wall-mounted installations where a small, reliable user interface is required for controlling displays, AV equipment and automation controllers.

Advantages

The control module combines IR learning functionality and RS-232 connectivity in a single compact unit, allowing centralized control of both infrared-only devices and serially controlled equipment. Its eight programmable buttons enable direct access to frequently used commands, and IR learning simplifies configuration by capturing signals from existing remotes. The unit’s compact footprint and standard mounting options make it suitable for integration into custom control panels and installation environments.

Suitable for

• Conference rooms and meeting spaces for display and AV device control
• Custom wall or rack panels in commercial AV installations
• Automation systems requiring a simple local user interface
• Integration into teaching spaces, lecture halls and small auditoriums

Key specifications

• Eight programmable front-panel buttons for user commands
• Infrared learning function to record and store IR remote codes
• RS-232 serial communication for direct control of compatible devices
• Compact panel format suitable for wall or rack mounting
• Low-profile design for installations with limited space

How to use

Mount the VISION control module in the chosen location and connect power and RS-232 cabling according to the system design. Use the IR learning mode to capture commands from existing remote controls by following the device’s programming procedure, then assign learned commands to the desired buttons. For serial control, configure the device addressing and baud rate compatible with the connected equipment and map commands to front-panel buttons or through the host control system. Test each programmed button and the RS-232 link to ensure reliable operation.

Recommendations

Place the module where the IR receiver has a clear line of sight to the controlled devices during learning and regular use. Document assigned button functions and serial command mappings to simplify future maintenance and updates. When integrating with a central control system, verify protocol settings and grounding to reduce communication errors.
