The Marantec Digital 992 bi.linked is a compact 2-channel mini remote transmitter designed for secure wireless control of garage doors, gates, and automation systems. Featuring advanced bi.linked radio technology and encrypted rolling-code security, the Digital 992 offers reliable operation in a convenient key-ring sized design.
The Digital 992 is a:
- Universal radio receiver module
- Designed for Marantec’s Bi·Linked wireless system
- Used to convert wireless remote commands into relay switching outputs
- Typically installed in:
- Garage door systems
- Industrial door controllers (e.g. CS series)
- Gate automation systems
In simple terms:
It is the “bridge” between modern Bi·Linked remotes and door/motor control electronics.
Bi·Linked Radio System
Core technology
Marantec Bi·Linked is their modern secure RF platform:
- 128-bit AES encryption (bank-level security)
- Rolling code system (code changes every use)
- Designed for high-security access control
Compared to older Multi-Bit:
- Much more secure
- Not fixed-code
- Resistant to cloning or replay attacks
Functional Overview
How it works
- Bi·Linked remote sends encrypted signal
- Digital 992 receives and decrypts it
- Internal relays switch outputs
- Door controller or motor is triggered
Key features
- 2 independent relay channels
- Each channel configurable:
- Pulse mode (momentary trigger)
- ON/OFF toggle mode
- External push-button inputs supported
- Programmable transmitter memory
Electrical Specifications
Power supply
Outputs
- 2 potential-free relay contacts
- Rated approx:
Input / logic
- Supports:
- SELV (Safety Extra Low Voltage) systems
- External wall buttons can be connected directly
Radio Specs
Depending on version:
- Frequency: 868 MHz (standard Bi·Linked band)
- Communication: Unidirectional (remote → receiver)
- Technology: Bi·Linked encrypted RF protocol
Memory Capacity
- Up to 100 transmitter codes per channel
- Total system capacity: up to ~200 stored codes (2 channels)
Each channel is independent:
- Channel 1 → Door A
- Channel 2 → Door B / light / secondary function
Construction & Protection
Housing versions
- IP20 (indoor cabinet mounting)
- IP65 (weather-resistant enclosure option)
Physical design
- Compact control module form factor
- DIN / enclosure mounting
- Screw terminal connections for outputs and inputs
Environmental Specs
- Operating temperature:
- Designed for:
- Electrical control cabinets
- Industrial environments (when IP65 version used)
Integration Use
The Digital 992 is used with:
Compatible systems
- Marantec Bi·Linked transmitters:
- Digital 506 / 517 / 564 / 663 etc.
- Door controllers:
- CS series (CS300, CS320, etc.)
- Third-party automation systems
Typical Applications
Residential
- Garage doors
- Gate automation
Commercial / Industrial
- Warehouse roller doors
- Access control systems
- Multi-door installations
Key Engineering Notes
Not compatible with Multi-Bit
- Bi·Linked ≠ Multi-Bit
- They use completely different encryption systems
High-security system
Bi·Linked uses:
- Rolling AES encryption
- Prevents signal cloning
- Stronger than older Marantec systems
Relay behavior matters
Each output can be configured as:
- Pulse (momentary trigger) → most common for doors
- Toggle (ON/OFF) → for lights or auxiliary systems
