What is an OPS or Slot-in PC and how do they work with CommBox interactive touchscreens?


OPS stands for Open Pluggable Source. At CommBox we call an OPS, Slot-In PC instead because we think it's a better name to describe it. It is a standardized form factor for Windows devices for interactive touchscreens.

The OPS specification defines a common interface and physical form factor for modular computing devices that can be easily inserted into compatible displays or digital signage screens. These devices, called OPS modules or OPS players, provide the computing power necessary to drive and control the display. In the case of CommBox Screens an OPS is used to add a Windows OS experience to interactive touchscreens and commercial displays.

Key features and benefits of an OPS include:

  1. Standardized Interface: OPS establishes a standard interface, connectors, and mounting mechanism for adding Windows to interactive touchscreens. This allows for compatibility and interchangeability between different displays and players that adhere to the OPS specification. CommBox uses an Intel form factor.

  2. Simplified Installation and Maintenance: With OPS, installations become more streamlined. OPS modules can be easily inserted or removed from compatible displays without the need for additional cables or complex setup. This simplifies installation and maintenance.

  3. Scalability and Upgradability: OPS allows for scalability and upgradability of interactive touchscreens. Display manufacturers, like CommBox can produce displays with OPS slots, and users can choose and replace OPS modules based on their computing needs or upgrade requirements. This flexibility helps extend the lifespan and adaptability of the digital signage infrastructure.

  4. Enhanced Aesthetics: OPS modules are designed to be discreet and integrated into the display, minimizing external cables and devices. This results in a cleaner and more professional-looking installation, with the focus on the display itself rather than visible computing equipment.

  5. Wide Compatibility: OPS modules support various operating systems and software applications, making them compatible with a wide range of digital signage software and content management systems. This compatibility allows users to choose the software and applications that best suit their specific needs.

OPS modules typically include components such as processors, memory, storage, graphics capabilities, network connectivity, and interfaces for connecting peripherals. The modules are designed to meet the performance requirements of digital signage applications, ranging from simple signage displays to more demanding interactive and multi-screen installations.

OPS has gained widespread adoption in the AV industry, and many display manufacturers like CommBox offer displays with built-in OPS slots or compatible OPS modules. This standardized approach simplifies integration, reduces compatibility issues, and provides a modular and scalable solution for classroom and office deployments.


If you would like to add Windows 10 or 11 to your interactive touchscreen, adding an OPS is an affordable way to do it. Give your users to option to use either the CommBox OS Android experience or Windows. To find out more about the CommBox Slot-In PC click here.
