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)
