The Digital 564 is a:

• Compact handheld Bi·Linked remote transmitter
• Used for garage doors, gates, and industrial door systems
• Designed for multi-device control in one remote

 It is one of Marantec’s most versatile 4-button remotes in the Bi·Linked range.

Bi·Linked Radio System

The Digital 564 uses Marantec’s modern Bi·Linked platform:

• 128-bit AES encryption (bank-level security)
• Rolling code system (code changes every transmission)
• Unidirectional communication (remote → receiver only)

Meaning:

Every button press generates a unique encrypted signal, making copying extremely difficult.

Buttons & Functionality

Controls

• 4 freely programmable function buttons

What they can control

Each button can be assigned to:

• Garage door 1 / 2 / 3
• Gate system
• Lighting or auxiliary relay
• Industrial door functions

---

LED feedback

• Red LED indicator
  • Confirms transmission

---

Frequency Options

Depending on region:

• 868 MHz version

 Important:

• Must match receiver frequency exactly
• 433 and 868 versions are not interchangeable

---

Electrical & Power Specs

• Battery: CR2032 lithium coin cell (3V)
• Low power consumption → long battery life
• Replaceable battery

---

---

Engineering Notes

Not compatible with Multi-Bit

• Bi·Linked ≠ Multi-Bit
• Completely different encryption system

---

Unidirectional system

• No feedback from door to remote
• (Unlike Digital 663, which is bidirectional)
