RFID reader DAHUA ASR1200E — RS-485/Wiegand interface, compact 96×43×17 mm, black

DAHUA ASR1200E is a compact RFID reader designed for access control and identification tasks. The reader supports both Wiegand and RS-485 interfaces, allowing integration with third‑party controllers as well as DAHUA access controllers. The housing is slim, water‑resistant and finished in black, with external dimensions of approximately 96 × 43 × 17 mm.

Advantages

The reader offers dual-interface connectivity (Wiegand and RS-485) for flexible integration with existing control systems. Its slim, water‑resistant design enables installation in a variety of environments. When powered from the controller over RS-485 the communication range is up to 100 m; with a separate power supply the RS-485 connection can extend up to 1000 m.

Suitable for

• Access control points in office or residential buildings
• Integration with third‑party access controllers
• Door entry and identification terminals where a compact reader is needed

Key specifications

• Interfaces: RS-485 and Wiegand
• Dimensions: 96 × 43 × 17 mm
• Color: black
• Enclosure: slim, water‑resistant design
• RS-485 communication range: up to 100 m when powered from controller; up to 1000 m with separate power supply

How to use

Connect the ASR1200E to a compatible access controller using either the Wiegand interface or RS-485. If using RS-485, powering the reader from the controller supports a communication range up to 100 m; using an independent power supply extends RS-485 range up to 1000 m. Mount the reader in a suitable location, observe correct wiring and sealing for outdoor installations, and configure the controller to recognize the reader according to the controller’s setup instructions.

Recommendations

For reliable long‑distance RS-485 communication, provide a stable separate power supply and use twisted pair cabling with proper termination. Ensure the reader is mounted so that its water‑resistant seals are intact for outdoor use.
