The Digital 572 is a:

• Compact handheld radio transmitter (garage/industrial remote)
• Part of Marantec’s Bi·Linked system
• Used to control:
  • Garage doors
  • Gates
  • Industrial door operators

 It is a portable 2-button remote, not a receiver or wall unit.

Bi·Linked Radio System

The Digital 572 uses Marantec’s modern Bi·Linked RF platform:

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

 This means:

Each button press sends a unique encrypted signal that cannot be cloned easily.

---

Controls & Functionality

Buttons / Channels

• 2 freely programmable function buttons
• Each button can control:
  • Door 1 / Door 2
  • Gate
  • Light or auxiliary relay (depending on receiver setup)

---

LED Feedback

• Red LED indicator
  • Confirms transmission
  • Battery / signal feedback (basic status)

---

Electrical & Power Specs

• Battery: CR2032 lithium coin cell (3V)
• Low-power design for long battery life
• Replaceable battery (no charging required)

---

Radio Frequency Options

The Digital 572 comes in two variants:

• 433 MHz version
• 868 MHz version

Both are Bi·Linked, but must match the receiver frequency exactly.

Physical Specifications

• Size: 39 × 60 × 12 mm
• Weight: ~0.03 kg (30 g)
• Housing: ultra-compact “micro remote” design
• Attachment: keyring loop / lanyard eyelet

Environmental Specs

• Operating temperature: −20°C to +60°C
• Designed for indoor/outdoor handheld use
• Resistant to normal industrial environments (dust, vibration, handling)

---

Compatibility

Works with:

Marantec Bi·Linked receivers:

• Digital 921
• Digital 941
• Digital 992
• Other Bi·Linked RF modules

Systems:

• Garage door operators
• Industrial door controllers (CS-series when equipped with Bi-Linked receiver)
• Third-party systems via compatible receivers

---

Security System

Key security features:

• AES 128-bit encryption
• Rolling code (changes every transmission)
• Device pairing required (learn mode on receiver)

 Security outcome:

• Prevents code copying
• Prevents replay attacks
• Each remote must be individually programmed

---

Engineering Notes

Not compatible with Multi-Bit

• Digital 572 = Bi·Linked system only
• Cannot pair with:
  • Multi-Bit receivers
  • Older CS radio modules

---

Direction of communication

• One-way transmitter
• No status feedback (unlike newer smart models like Digital 663)

---

System hierarchy

Remote → Bi·Linked receiver → controller → motor
