The Marantec Digital 992 bi.linked is a compact 2-channel radio receiver designed for secure wireless control of all types of automatic doors, gates, and third paty automation systems. Featuring advanced bi.linked radio technology and  128Bit rolling-code encrypted.

The Digital 992 is a:

• External 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
  • 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

1. Bi·Linked remote sends encrypted signal
2. Digital 992 receives and decrypts it
3. Internal relays switch outputs
4. 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

• 12–24 V AC/DC

Outputs

• 2 potential-free relay contacts
• Rated approx:
  • 24V AC / 1A
  • 30V DC / 1A

---

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)

---

Environmental Specs

• Operating temperature:
  • −20°C to +60°C

---

Integration Use

The Digital 992 is used with:

Compatible systems

• Marantec Bi·Linked transmitters:
  • Digital 506 / 572 / 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 encryption than older Multibit 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
