Marantec Bi.Linked Digital 663

The Digital 663 is a:

Premium Bi·Linked handheld remote transmitter
Designed for garage doors, gates, and industrial door systems
Uses Marantec’s modern encrypted rolling-code platform

It is not a receiver or wall switch — it is a smart 3-button remote with status feedback capability.

Bi·Linked Radio System

The Digital 663 operates on Marantec’s Bi·Linked system, which is their newest wireless standard:

128-bit AES encryption (high-security level)
Rolling code (changes every transmission)
Bidirectional communication (key feature)
Supports status feedback from door to remote

This means:

The remote doesn’t just send commands — it can also “ask” and receive door status.

Bidirectional Features (Key Difference)

The Multi-Bit Digital 663 can :

Check if door is:
- Open
- Closed
- Moving

LED feedback system

Red LED → door open / opening
Green LED → door closed / closing
Flash patterns indicate movement direction

Buttons & Control Logic

Channels

3 freely programmable function buttons
- 1 status/query button

Assignable functions

Door 1 / Door 2 / Door 3
Gate open / close
Light control
Special automation inputs

Each button can be individually mapped to a receiver channel.

Radio Frequency Options

Depending on region:

868 MHz version (most EU / industrial systems)

Memory & Pairing

Pairing method

“Learn mode” on Bi-Linked receiver (e.g. Digital 992, 921, 941)
Each button is learned individually

Security

Rolling code prevents cloning
Each press generates a new encrypted code

Physical Specifications

Dimensions: ~39 × 92 × 12 mm
Weight: ~40 g
Housing: compact mini remote
Attachment: keyring loop + optional wall bracket included

Environmental Specs

Operating temperature: −20°C to +60°C
Indoor/outdoor portable use
Resistant to normal industrial conditions

Compatibility

Works with:

Marantec Bi·Linked receivers:
- Digital 921 / 941 / 992
Bi·Linked door operators
Integrated control systems (CS-series when fitted with Bi-Linked receiver)

Important Engineering Notes

Not compatible with Multi-Bit

Completely different system
Multi-Bit = fixed code
Bi-Linked = rolling AES encryption

Bidirectional requirement

Only works fully if paired with Bi-Linked receiver capable of feedback
Without that, it behaves like a normal remote (send-only)

Technical Summary

Type: 3-channel smart handheld transmitter
System: Bi-Linked (AES 128-bit rolling code)
Frequency: 868 MHz
Power: CR2032 battery
Functions: 3 programmable buttons + status query
Communication: bidirectional
Feedback: LED status indication (open/close/movement)
Range: typical RF 30–100 m (environment dependent)
Size: ~39 × 92 × 12 mm

Marantec Bi.Linked Receiver Digital 992 868Mhz

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

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

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
