Main Features

bi.linked Radio Technology

The Digital 991 uses Marantec’s bi.linked radio platform, which supports encrypted communication and improved reliability versus older Multibit systems. Third-party distributor documentation references 128-bit AES encrypted radio transmission.

Universal Integration

The receiver can:

  • Plug directly into Marantec systems
  • Operate third-party motors and gate controllers
  • Retrofit older automation systems

This makes it useful when replacing obsolete radio systems while keeping the original motor/controller.

Compact Form Factor

At only 37 × 53 × 13 mm, the module fits easily inside most control cabinets or operator housings.

Large Memory

Stores up to 200 remote controls/transmitters.

Compatibility Notes

The Digital 991 is designed for:

  • Industrial doors
  • Garage doors
  • Sliding gates
  • Swing gates
  • Barrier systems

Compatible with:

  • Marantec bi.linked remotes
  • Certain Marantec Digital transmitters
  • CS 320 controllers
  • Third-party automation systems using impulse input

It is not compatible with older Marantec Multibit transmitters unless specifically supported by the receiver generation. Reddit installer discussions confirm confusion between Multibit and bi.linked compatibility is common.
